Autonoma leveransfordon i interaktion. Inom projektet GLAD (Goods deliveries under the LAst mile with autonomous Driving vehicles) genomfördes under maj månad en användarstudie där en ADV (Automated Delivery Vehicle) utrustad med s.k. eHMI:er (visuella medel som kommunicerar till människor i omgivningen) körde en kortare rutt. Syftet var att utvärdera hur individer uppfattade och förstod eHMI:erna i olika situationer, samt hur de kan utvecklas. Preliminära resultat indikerar att eHMI:erna i sig inte kommunicerade sina specifika budskap, men att de i sina givna sammanhang blev begripliga. Resultaten visade även på tydliga inlärningseffekter, d.v.s. deltagarna lärde sig snabbt eHMI:ernas budskap. Projektet är finansierad av Trafikverket och utförs av RISE, Clean Motion, Aptiv, Combitech och Högskolan i Halmstad. Kontakt: Mikael Söderman, RISE, (mikael.soderman@ri.se)

Förstudie SMART-projektet. Som en del av det EU-finansierade SMART-projektet genomför RISE en förstudie kring förutsättningarna för att komplettera kollektivtrafiken med förarlösa tjänster i Skaraborg. Projektet leds av Destination Läckö/Kinnekulle som är ett kommunalt bolag ägt av Götene och Lidköping. Preliminära resultat visar att det i några av tätorterna finns intressanta systemeffekter värda att studera närmare men att det är svårt att hitta lämpliga lösningar för lite längre avstånd mellan kollektivtrafikens hållplatser och populära utflyktsmål eller uppför Kinnekulles de branta vägar. Det finns också sträckor i området där det antagligen finns en marknad för kommersiella tjänster med manuellt framförda fordon. Kontakt: Håkan Burden, RISE, (hakan.burden@ri.se)

Generering av dimma och väderklassificering. RISE och Veoneer har under våren 2022 genomfört en förstudie ”Dimhöljt” för lära hur dimma kan skapas i klimatkammare. Syftet med den genererade dimman är att testa lidar, t ex för att filtrera bort störningar, för att validera simuleringsmodeller, för att verifiera sensorprestanda eller för att verifiera att en funktion är inom ODD. Det finns i princip tre olika sätt att slå sönder vatten till fina droppar: med vibrationer, med trycksatt vatten eller med tryckluft; man kan även generera dimma genom att kondensera ånga. Dimma är våta aerosoler i storleksordning från våglängden av synligt ljus till en faktor 20-50 ggr större. Projektet har också undersökt hur mätning av dimmans karaktäristik utförs på lämpligt sätt. Mätningar måste bland annat inkludera storleksfördelning av partiklar och mängden vatten i flytande form. Det är viktigt att skapa repeterbart testsystem med dimma. I projektet studerades därtill hur man med en lidar kan klassificera vädertyper såsom dimma, regn, snö, klart väder. Studien baserades på mätningar utomhus och i klimatkammare. De inledande försöken har varit framgångsrika och tanken är att förstudien ”Dimhöljt” följs av en fördjupad ansats. Förstudien delfinansierades av Vinnova/FFI, 2021-02582.

Syntetisk data för validering. En vanlig utmaning inom maskininlärning är att ta fram realistisk data både för att träna sina nätverk samt för att validera dem. I dag är en vanlig metod att samla in data i den miljö där nätverket ska appliceras, t.ex. i trafiken, och sedan hoppas att det resulterande datasetet ska vara representativt. Detta är tyvärr sällan fallet eftersom att det är svårt att få med alla tänkbara scenarion. Inom FFI-projektet DIFFUSE utvecklas metoder för att skapa syntetisk data och bilder primärt för valideringssyften. Tanken är att förbättra de maskininlärningsmetoder som i dagsläget bara i begränsad omfattning ger kontroll över vad den resulterande bilden innehåller.

Säkerhetskultur för automatiserade fordon. Målet för projektet Säkerhetskultur för automatiserade fordon är att utveckla metoder och verktyg för att kunna hantera säkerhetskulturen i organisationer som konstruerar och implementerar automatiserade fordon och maskiner. Projektet kommer att utforska befintlig säkerhetskultur och nya risker, samt utveckla mätinstrument för säkerhetskultur och pröva hur de kan appliceras på hållbarhet- och jämställdhetskultur. Säkerhetsfokus har länge legat på fordon och förare. Nu behövs organisationens och kundens betydelse lyftas fram. I projektet kommer därför en modell och verktyg utarbetas för att integrera säkerhetskultur i utvecklingsarbetet och för att stötta en lärandeprocess. Modellen utvecklas och utvärderas på två fallstudier från olika domäner, dels autonoma truckar samt automatiserade bussar i projektet Ride the future. En viktig aspekt av projektet är kunskaps och metodiköverföring mellan de olika tillämpningarna och mellan parterna VTI, RISE, Volvo GTT, Combitech och Toyota material handling. Projektet finansieras av Vinnovas FFI-program och genomförs på två år under ledning av VTI. Kontaktperson: Christina Stave (christina.stave@vti.se).

Studie om lastbil-VRU interaktioner inom FFI-projekt. Inom ramarna för FFI-finansierade projektet ”Externa interaktionsprinciper för förtroende och acceptans av tunga autonoma fordon” som bedrivs av Scania, RISE och Högskolan i Halmstad har doktoranden Victor Fabricius och kollegor publicerat en vetenskaplig tidskriftsartikel ”Interactions Between Heavy Trucks and Vulnerable Road Users—A Systematic Review to Inform the Interactive Capabilities of Highly Automated Trucks”. Artikeln syftar till att ge en översikt av den vetenskapliga litteraturen gällande dagens interaktioner mellan tunga lastbilar och oskyddade trafikanter – mer specifikt fotgängare och cyklister. En av insikterna från studien är att en stor del av interaktionen består av implicit kommunikation som till exempel fordons körsätt och rörelsemönster, och att den här typen av kommunikation i framtiden troligtvis kommer utgöra grunden även för interaktioner med automatiserade fordon. En annan insikt från studien är också att explicit kommunikation, i form av exempelvis ljussignaler på lastbilen i syfte att förtydliga lastbilens avsikter och handlingar, kan vara till nytta för interaktionerna. Utformning och nyttan av sådan kommunikation undersöks vidare i projektet som pågår fram till mitten av oktober 2022.

Autonomous vehicle interactions in the hub. Scania, RISE, Boliden and Icemakers are working together in a research project “In the Hub – Samspel mellan operatörer och förarlösa fordon i framtidens transportsystem” funded by FFI. The aim is to investigate how natural interaction technologies can be integrated into autonomous transport systems to facilitate efficient and engaging experience in the hub contexts. An exploratory study have examined the potential of using verbal interaction and augmented reality (AR) to facilitate collaborations between professional human operators and unmanned self-driving heavy vehicles. Concepts that support operators in loading situations were designed and evaluated with forklift operators and rock-loading operators during a video-based study. Overall, the concepts received high scores in perceived efficiency and user experience. The results from the forklift operators supported the idea that more natural and social verbal interaction between operators and unmanned vehicles could lead to increased trust and acceptance compared to using simple voice commands. However, the results from the rock-loading operators showed that extensive use of voice interaction could become disturbing. The exploratory study thus supports the potential of using and further exploring verbal interaction and AR to facilitate human operators’ collaboration with self-driving vehicles, and the proposed concepts provide promising examples of interaction models for further investigation and implementation. The results have been presented in a paper which will be published in the conference “Applied Human Factors and Ergonomics” this year.

Heavy Automated Vehicle Operation Center (HAVOC) – Requirements and HMI design is a recently completed FFI-funded research project conducted by RISE and Scania with the following final project summary: Development trends suggest that, in spite of the optimistic announcements made by some stakeholders a few years ago, there are still technological challenges and regulatory constraints making heavy automated vehicles (HAVs) dependent on human control. Indeed, most HAV still require a human safety operator in the vehicle, and automated driving without a human “fallback” might be distant. At the same time, having a human safety operator in the vehicle jeopardises major anticipated benefits of HAVs – transport safety and efficiency. To bridge this gap, stakeholders are exploring remote operation technology, which enables HAV to be remotely operated by a human operator to some extent. The purpose of the HAVOC project was to study operator work and HMI for remote monitoring and control of heavy autonomous vehicles. The aim was to answer the following research questions:

  • What requirements are imposed on people and heavy vehicles for assessment, assistance, and driving?
  • What is required to scale the ratio between the number of operators and the number of monitored vehicles?
  • How should operator work be designed for transitions between assessment, assistance, and driving?
    A simulator was developed in Unity game engine with corresponding 3D-world and operator HMI to enable exploration of remote operation of ten vehicles in parallel. In a user study, 15 participants were invited to work for 1.5 hours and evaluate the system and work in terms of human-automation interaction. Human factors and HMI requirements were elicited for remote assessment, remote assistance, and remote driving operator tasks. The results show the importance of taking a systems perspective in developing and implementing remote operation control centers. See this link for an overview of the study and its results.
  • One of the major takeaways from the user study and the HAVOC project is the importance of a systems perspective in the analysis and design of future remote operation centers. The answer to questions such as “How many operators are needed?, How many vehicles can be monitored and controlled?, What is the best HMI?, What are the most important operator tasks?”  etc., will always rely on the dependencies between multiple human, technical and organizational factors. The ability to deal with the dependencies between factors such as operators’ skills and knowledge, operator tasks and training, HMI, vehicle capabilities, operational context, etc., lies in defining the envisioned work system and deciding what to design for. If a viable business case for remote operation is an operator:vehicle ratio of 1:1, 1:10 or 1:100 will place very different demands on overall human-automation systems design and work organisation. In this project, we have only considered single operator work. In a real application, teamwork between remote operators, traffic planners, and field personnel can be expected, further stressing the socio-technical systems approach.

Det här är svenska guldkorn ifrån er läsare. Stort tack för alla bidrag, och tack för ert fantastiska jobb.

PhD thesis: Decision-Making in Autonomous Driving using Reinforcement Learning.
This thesis explores different techniques based on reinforcement learning (RL) for creating a generally applicable decision-making agent for autonomous driving. One highlight is the introduction of methods that can estimate how confident the trained agent is in its decisions, which for example is important if the agent is exposed to situations outside of the training distribution. Another contribution is a method for combining planning and RL, which both improves the quality of the decisions and reduces the required amount of training samples. The full text is available here. This project was supported by Volvo Group, Chalmers, Wallenberg AI, Autonomous Systems and Software Program (WASP), Vinnova FFI, and AI Sweden.

L3Pilot – Piloting Automated Driving on European Roads
The L3Pilot project (https://l3pilot.eu/) is the largest EU project on automation so far and ended in October 2021. In this project, Chalmers and Volvo Cars investigated human collaboration with automated vehicles. The Wizard of Oz approach was used both on test track and on public roads to simulate an automated driving feature that did not require drivers to supervise the system. However, the drivers occasionally had to resume manual driving in response to take-over requests. More information about the participants and the publications from this project can be found here.

Long-term demonstration of autonomous shuttle fleets in Gothenburg will run between spring 2022 and 2023 as part of the H2020 project SHOW – SHared automation Operating models for Worldwide adoption (https://show-project.eu/). Main contribution of the real-life urban demonstration is the integration of fleets of automated vehicles into public transport, to advance sustainable urban mobility, combined with evaluations of technical solutions, business models, user acceptance and scenarios for impact assessment. The project aims to be the biggest and most holistic initiative ever piloting automated vehicles in urban environments. Real-life urban demonstrations will take place in 20 cities across Europe, such as in Madrid, Turin, Salzburg, Rouen, and Linköping. SHOW gathers a strong partnership including 69 partners from 13 EU-countries and fosters international cooperation. The demonstration in Gothenburg will take place at Campus Johanneberg/Chalmers University of Technology with partners Keolis, Ericsson and RISE. The project has received funding from the European Union’s Horizon 2020 research and innovation programme. For more information contact Cilli Sobiech (cilli.sobiech@ri.se).

Demonstrating remote controlled trucks at Lindholmen/Gothenburg. Within the project SCAT – Safety Case for Autonomous Trucks we will demonstrate goods transport without a safety host onboard and with higher velocity in a mixed traffic environment at Lindholmen (https://www.ri.se/en/what-we-do/projects/safety-case-for-autonomous-trucks). The demonstration will take place in spring 2022. The project started in autumn 2020 with partners RISE, Ericsson, AstaZero, Telia and Einride. The consortium explores together how to safely handle remote access and control from a technical safety perspective and from a policy perspective to support future commercialisation of automated vehicles. We consider the gaps and challenges related to the safety of automated trucks, the digital infrastructure, the policy framework in different markets and their behavioural implications. The approach includes the legal/policy framework in Sweden, as well as France and the US exemplarily. The project is funded through the strategic innovation program Drive Sweden by Vinnova, Formas and the Swedish Energy Agency. For more information contact Cilli Sobiech (cilli.sobiech@ri.se).

Digital traffic rules for a connected and automated road transport system. In the framework of Drive Sweden Policy Lab 2021/22, one case study is identifying ways towards a future system for digital traffic rules (https://www.drivesweden.net/projekt-3/drive-sweden-policy-lab). We raise issues concerning the development of traffic regulations in Sweden through dialogue with a wide range of actors. The purpose is to investigate what is needed to create conditions for a future system with traffic rules that are geographically unambiguous and can be read by machines. Reliable information is needed already today for various applications and supporting IT systems and will become increasingly important with a connected and automated road transport system. We use policy labs as a method to find a possible solution, for example through the development of the regulations that govern how traffic regulations are decided and announced. A development of processes and routines for production, management and exchange of traffic rule data would reduce the risk of deviations that we see today. The project can contribute by looking at challenges, opportunities and alternative solutions linked to the regulations. Drive Sweden Policy Lab is a platform for collaborative policy development enabling smart mobility solutions. The platform gathers governmental agencies, municipalities, multinational corporations, start-ups and research to solve bottlenecks for innovative projects. The project Drive Sweden Policy Lab 2021/22 is funded through the strategic innovation program Drive Sweden by Vinnova, Formas and the Swedish Energy Agency.

External interaction principles for creating trust in heavy automated vehicles. To become widely used on public roads, future automated vehicles (AVs) will need to be trusted and gain societal acceptance – something that will be greatly affected by their ability to safely, efficiently and seamlessly interact with other road users in the traffic system. This project investigates if there will be new communication needs when heavy AVs are introduced in traffic. More specifically, the project is investigating how trust and acceptance of heavy AVs can be created and maintained via External Human-Machine-Interfaces (eHMI). Currently, the project has conducted a series of studies including a virtual reality simulator study, and two Wizard of Oz studies on a test track. These studies have been focused on interaction between heavy AV’s and pedestrians. Our next goal is to investigate interaction between heavy AV’s and passenger car drivers using a driving simulator. The project is supporting an institute PhD candidate, and has also hosted two master thesis projects together with Umeå University: Designing eHMI for trucks: How to convey the truck’s automated driving mode to pedestrians and Communicating the stopping intent of an autonomous truck: The interplay between content size, timing and truck speed. This project is financed by Fordonsstrategisk Forskning och Innovation (FFI), associated to SAFER and led by Scania with RISE and Halmstad University as partners.

Policy Lab Smarta Fartyg. Projektet undersöker hur den pågående digitaliseringen inom svensk sjöfart rimmar med dagens regelverk. Analysen görs utifrån tre konkreta fall. Två av fallen berör hur autonoma funktioner på ett godtagbart säkert sätt kan ta över människans ansvar ombord utifrån konstruktion och användningsområde. Till skillnad från fordon finns det ingen försöksförordning för autonoma fartyg så arbetet utgår från de regler och undantag som etablerats under en epok när befälhavaren alltid var ombord. I det tredje fallet samverkar två myndigheter kring hur en förändring av dagens lotsplikt kan påverkas av nationella behov och förutsättningar samtidigt som det kommer nya internationella regler. Parter i projektet är Transportstyrelsen, Sjöfartsverket, Saab Kockums, ABB, Färjerederiet och RISE. Projektet finansieras av Trafikverket.

Precog: Kravhantering för säkra maskininlärningsbaserade perceptionssystem för autonom mobilitet. Självkörande fordon kräver tillförlitliga perceptionssystem. Framgångsrika perceptionssystem förlitar sig på maskininlärning. Maskininlärning bygger på träningsdata av hög kvalitet. Vad innebär detta för fordonens perceptionssystem? Hur kan vi specificera förväntningarna på träningsdatan? Vad innebär kvalitetssäkring på data-nivån? Hur påverkas fordonets funktionssäkerhet på systemnivån? Den nystartade förstudien Precog genomförs av RISE, Göteborgs universitet, Annotell och Zenseact med stöd från Vinnova. Projektet kommer att skapa samsyn för krav på maskininlärningsbaserade perceptionssystem för fordon. Precog ska utreda kedjan 1) annoteringsnoggrannhet för träningsdata, 2) maskinlärningsmodellernas precision, 3) perceptionssystemens korrekthet och 4) funktionssäkerhet. Förstudien kommer att organisera en serie workshops med nyckelspelare inom svensk fordonsindustri. Vidare kommer dessa workshops att kompletteras med djupintervjuer och litteraturstudier. Efter syntes av projektresultaten kommer vi att arrangera en öppen workshop för att delge våra slutsatser under våren 2022. För mer information kan ni kontakta Markus Borg (markus.borg@ri.se)

Motion-Planning approach for autonomous bus driving. A collaboration between Scania and KTH Royal Institute of Technology resulted in the development of a novel Motion-Planning approach for autonomous bus driving. The results of this collaboration have been recently presented in the IEEE Vehicular Technology Magazine (https://ieeexplore.ieee.org/document/9470918). The article presents a motion-planning framework that leverages expert bus driver behavior, increasing the safety and maneuverability of autonomous buses. To deploy autonomous driving technologies in urban public transport, many challenges related to self-driving buses still need to be addressed. Unlike passenger cars, buses have long and wide dimensions and a distinct chassis configuration, which significantly challenges their maneuverability. To deal with the bus special dimensions, the authors introduce a novel optimization objective that centers the whole bus body as its travels along a road. Furthermore, the authors present a new environment classification scheme that enables self-driving buses to take advantage of the elevated overhangs, to increase maneuverability. Finally, a novel collision checking method is presented that explicitly considers a bus’s front wheels and how they can protrude from beneath the chassis when maneuvering near stops. The benefits of the proposed solution are presented through exp8eriments using an autonomous bus in real road scenarios. The work was partially supported by the Wallenberg AI, Autonomous Systems and Software Program (WASP) funded by the Knut and Alice Wallenberg Foundation.

Industrial PhD project: Machine Learning to Enhance AI Planning for Intelligent Autonomous Transport Systems. Scania has developed an Offboard system by which its autonomous vehicles can be controlled and managed to perform their operations. This Offboard system can allow an automated planning and scheduling system (a.k.a. AI Planner) to create missions (plan) and dispatch them to the autonomous vehicles. Scania is now researching how to improve AI planning methods for fleets of autonomous vehicles using Machine Learning (ML) techniques. Learning algorithms will support AI planners in order to save human effort leading to good quality plans in less time, thus overcoming the challenge of depending upon the fleet transport managers experience. The PhD project’s outcome is expected to help Scania’s Offboard ATS to improve the plan quality and enable the system to scale up so that it could deal with the future challenges as autonomous vehicles will be taking over in many areas that are of immediate interest to Scania. The project, partly founded by the Swedish Foundation for Strategic Research (SSF), started in April 2020 and it will last 4 years, leading to a PhD degree from Örebro University.

Thesis on Cyber Resilient Vehicles. Cyber security focuses on detecting and preventing attacks whereas resilience concentrates on maintaining the vehicle’s intended operation in the presence of faults and attacks, which may even require the vehicle to disable some functionality to protect the passengers in and around the car. This becomes more important when higher levels of autonomy are introduced. In this thesis, we provide methods that aid practitioners in identifying and selecting the necessary and appropriate security and resilience techniques during the design of an automotive system. Additionally, this thesis also proposes three techniques to secure them, namely a mechanism to secure the internal communication, a model to assess a vehicle’s behaviour and reliability when it is driving in traffic, and a framework to detect attacks and anomalies in a vehicle fleet. This thesis was partially supported by the VINNOVA FFI projects HoliSec, and CyReV Phase 1 & 2. For more information contact Thomas Rosenstatter (thomas.rosenstatter@ri.se).

Enhanced ADAS – nästa generations ADAS. Advanced Driver Assistance Systems (ADAS) have the potential to improve traffic safety and efficiency. However, there are challenges with these systems in terms of their limited situation awareness and insufficient driver-vehicle interaction capabilities. If not addressed, these could lead to poor driver experience and decreased use of these systems. This project is led by RISE together with Aptiv and Smart Eye as partners. The aim of this project is to explore how safety, efficiency and drivers’ experience, acceptance and trust can be enhanced by enriching the situation awareness of existing ADAS with real-time information from a) digital road maps, b) driver monitoring, and c) by incorporating dynamic driver-vehicle interaction strategies. The project aims to include two iterations of prototypes with testing of each one on public roads or test track. The first iteration of prototypes has been evaluated and was completed now in december together with expert participants that work in the field of automotive technology. We have received valueable feedback for initiating the second iteration where we aim to develop ADAS functionality together with an intelligent vehicle-driver interface that derives information from internal and external vehicle sensors, as well as digital road maps. This project is financed by Fordonsstrategisk Forskning och Innovation (FFI). For more information contact Niklas Strand (Niklas.strand@ri.se)

The focus of automation in the Project I.hamn. Sweden’s ports are facing a major challenge to function as a transport node in the transformation to a more sustainable transport system that is expressed through the UN’s goals for sustainable development and the strategy for transferring freight transport from land to sea and rail. This means a higher pressure on infrastructure and resources, which places demands on new capabilities in the execution of the port’s operations. Ports need to be more efficient, enable sustainable transport and become a natural node in the integrated transport system. The project I.Hamn (https://www.ri.se/sv/vad-vi-gor/projekt/ihamn) gathers a continuous expanding cluster of today 22 Swedish small and medium sized ports allowing them to join forces to lower thresholds in adopting solution associated to digitalisation, automation, and electrification. The project also involves system and infrastructure suppliers, and other port stakeholder, such as shipping lines, authorities and industry associations. During 2020/2021 the vision of the future port has been co-developed together with involved ports and its stakeholders, through workshops and interviews. Based on the vision, a number of demonstrators are planned for in the areas of electrification, digitalisation, and automation. The demonstrators aim to identify potential and future solutions, based on the capabilities required to realize the vision of the sustainable port. Examples within the area of automation that are exploited are auto-mooring, automatic loading operations, autonomous transports in the port area and automatic hinterland entry and exits to the port. I.hamn is a three-year demonstration project funded by the Swedish Transport Administration within the framework of the Lighthouse industry program for sustainable shipping and coordinated by RISE together with Chalmers and GU.

Passagerares upplevelse av självkörande fordon

Förberedelserna för en massdemonstration av självkörande fordon i EU rullar på i SHOW-projektet. Som vi nämnt tidigare så är allmänhetens acceptans en nyckel för lyckad introduktion av autonoma fordon. RISE:s nederländska kusin TNO har av denna anledning sökt analysera passagerares upplevelse av autonoma fordon i stadsmiljö, mer specifikt när de närmar sig korsningar med trafiksignaler. I testet undersöktes både normalfall och när person utanför fordonet går mot rött [1].

Egen kommentar

RISE leder den svenska mega site:n i SHOW-projektet och har tidigare bland annat forskat på medtrafikanters uppfattning av och beteende runt autonoma fordon (exempel ett och två). Det ska bli spännande att läsa om resultaten ifrån studien framöver.

Autonomt leveransfordon på Nordstans tak

Det svenska forskningsprojektet GLAD (Goods delivery under the Last mile with Autonomous Driving vehicles) där RISE, Aptiv, Clean Motion, Combitech och Högskolan i Halmstad undersöker interaktionen mellan autonoma leveransfordon och andra trafikanter har nu utfört tester med fotgängare på Nordstans tak [1].

Projektets fokus är på acceptans och tillit till sådana fordon, men berör också andra aspekter så som den självkörande tekniken, metodik för utvärdering av externa gränssnitt på autonoma fordon, affärsmodeller samt digital och fysisk infrastruktur.

Projektet som är finansierat av Trafikverket påbörjades i mars 2019 och är planerat att avslutas i augusti 2021.

Resultat från Självkörande landsbygd

Projektet Självkörande landsbygd har precis avslutats [1]. I projektet har man utifrån behoven, tekniken och infrastrukturen, samhällsnyttan samt rollerna och ansvaren tagit fram ett underlag för upphandling av autonoma fordon för användande i kollektivtrafik på landsbygden. Genom intervjuer, workshops och en förfrågan om information (RFI, se Appendix B i rapporten) har projektet undersökt frågan utifrån fyra konkreta områden i Sverige – Lund, Gotland, Eskilstuna och Skellefteå. 

Med en definition av landsbygd baserad på individens mobilitet (sid 11 i rapporten) har studien kommit fram till att Sveriges landsbygd rymmer mindre orter på väg att avfolkas där äldre, barn och de utan körkort hade kunnat få bättre tillgång till samhällelig service med autonoma fordon (sid 37). Studien har också identifierat att flera av landets nya arbetsplatser kommer befinna sig på landsbygden och därmed skapa ett mobilitetsbehov från staden till landet (sid 51). 

För att kunna realisera de identifierade möjligheterna finns ett behov av att framföra fordonen i högre hastigheter samt att de ska kunna hantera mer komplexa trafiksituationer än vad dagens piloter med autonoma fordon i städerna visat (sid 55-57). Samtidigt påpekar studien att man inte ska förvänta sig att investeringarna i autonoma fordon kommer betala sig på en linje, snarare behöver man lyfta blicken och se systemeffekten när stomlinjetrafiken blir mer attraktiv då bussarna går raka vägen istället för via mindre samhällen (sid 25). 

Studien har inte sett några belägg på att den digitala infrastrukturen behöver utvecklas för att möjliggöra försök med autonoma fordon på någon av de undersökta rutterna. Dagens 4G-täckning är fullgod och fordonen borde ha tillgång till tillräckligt bra positioneringsdata för att bedriva verksamheten. Däremot ställs flera frågor om hur ersättningstrafiken organiseras när fordonen inte klarar av vädret, vem som står för säkrare hållplatser och hur chaufförens övriga ansvar realiseras när fordonet är förarlöst. 

Projektet har letts av RISE och genomförts i samarbete med Ramboll, Trafikverket, Lund, Gotland, Eskilstuna och Skellefteå. Projektet har finansierats av VINNOVA via Drive Sweden.

Egen kommentar

Det har varit ett roligt projekt att få vara med i. Mycket för att det finns så många engagerade människor som vill se en annan utveckling för Sveriges landsbygd, men också för att det blev så tydligt att den där mentala bilden med den slingrande grusvägen bara berättar en väldigt liten del av möjligheterna och utmaningarna med mobilitet på landsbygd. Jag blev nog mest överraskad av att Eskilstuna Logistikpark ligger på landsbygden och mest nöjd med diskussionerna vi haft kring hur investeringarna i nya fordon kan motiveras. Eller inte. På vissa platser är det nog rimligare att leta efter andra lösningar tills det går att leverera en hållbar tjänst.

Förhindra åksjuka med hjälp av ljud?

Volvo Cars har tillsammans med RISE och det svenska företaget Pole Position Production gjort ett projekt med fokus på tillit och åksjuka i självkörande fordon där passagerare ska få en ljudsignal innan fordonet gör manövrar så som acceleration och skarpa svängar [1].

Tanken är att passagerarna ska hinna justera sig inför en rörelse, och resultaten har visat att passagerare både känner sig mindre åksjuka och även litar mer på fordonet. Enligt Justyna Maculewicz, som är användarupplevelsedesigner på Volvo Cars, har utgångspunkten varit i att anpassa naturliga billjud som exempelvis motorljud snarare än att använda röst- och pip-ljud för detta. Här kan ni höra ett exempel på framtagna ljudsignaler.

Vi berättade även om det här FFI-projektet innan jul, läs mer här.

Tesla ombeds återkalla 158 000 bilar. Detta efter att en undersökning från den amerikanska säkerhetsorganisationen NHTSA visat att pekskärmen slutar fungera i vissa av Model S (2012-2018) och Model X (2016-2018). Felet sägs bero på att en hårddisk i systemet blir full, vilket då kräver hårdvarubyte. Detta är ett av felen som helt enkelt får inte inträffa. Det intressanta i sammanhanget är att Tesla kopplat bilens vitala säkerhetsfunktioner så som hastighetsindikator till samma pekskärm, och när den slutar fungera så utgör bilen en säkerhetsfara. Länk

NHTSA ändrar sig. Lite grann i alla fall. Strax innan jul publicerade den amerikansak säkerhetsorganisationen NHTSA ett dokument kallat Notice Regarding the Applicability of NHTSA FMVSS Test Procedures to Certifying Manufacturers. Där klargör organisationen att de ändrat sitt krav från 2016 gällande certifiering av fordon. De kommer inte längre kräva att tillverkare av fordon utan traditionella kontroller ska följa FMVSS-testförfarandena som grund för certifiering: “Accordingly, NHTSA is rescinding the portions of the 2016 Google Interpretation stating that manufacturers must ensure that NHTSA could conduct the FMVSS test procedures on the vehicle using the test conditions and procedures specified in the standard. Instead, the Agency clarifies that for those vehicles with designs that preclude testing under existing FMVSS test conditions and procedures, a manufacturer acting in good faith and exercising reasonable care may certify the vehicle as compliant even if the Agency cannot conduct the exact test procedure set forth in the standard.” Huvudpoängen här är att NHTSA spikar självcertifiering som en vädertagen process för automatiserade fordon. Personligen tycker jag att NHTSA utryckt sig lite otydligt och att det kan vara svårt för tillverkarna att veta vad som krävs exakt. Länk

Guldkorn från svensk forskning 2020

Trust in What? Exploring the Interdependency between an Automated Vehicle’s Driving Style and Traffic SituationsAs the progression from partial to fully autonomous vehicles (AVs) accelerates, the driver’s role will eventually change from that of active operator to that of passenger. It is argued that this change will lead to improved traffic safety, as well as increased comfort. However, to be able to reap the benefits, drivers must first trust the AV. Research into automation has shown that trust is an important prerequisite to using automation systems, since it plays an important role in creating user acceptance and in generating a positive user experience. Moreover, for the purposes of safe AV operation, it is important that the user’s trust in the automation is appropriate to the actual capabilities of the system. One important aspect that can build user trust is to conveyvehicle capability, something which is commonly communicated via displays located in the cockpit of the vehicle. However, it has also been shown that parameters such as lateral steering also provide the driver with an understanding of the vehicle’s capability. Therefore, driving styles, or how the act of driving an AV should be conducted, may affect a user’s trust. However, little research has been conducted on the impact of driving styles in AVs in everyday traffic situations; that is, situations often encountered in a day-to-day driving context, such as stopping for a pedestrian at a zebra crossing or overtaking a moving vehicle. An experimental study with 18 participants was conducted on a realistic test course using a Wizard of Oz approach. The experiment included seven everyday traffic situations that the participants’ experienced with two different driving styles, Defensive and Aggressive driving style. The results show that characteristics of everyday traffic situations have an effect on the users trust in automated vehicles (AVs). Primarily due to perceived risks (for oneself and others), task difficulties and how the AV conforms to the user’s expectation regarding how the AV should operate in everyday traffic situations. Furthermore, the results also show that there are are interdependencies between situational aspects and how the AV driving behaviour conducts actions. Thus, the AV driving behaviour needs to be designed to operate differently depending on the traffic situation, to enable the user to create an appropriate level of trust, in relation to the actual performance of the AV. Finally, trust results from the information provided by the AV’s behaviour, what it explicitly communicates via displays, and how these factors relate to the driving context. Thus, a systems approach is necessary, in which the interaction between user and automation is key, but without neglecting the equally important contextual aspects. This study was funded by Vinnova, Sweden’s Innovations Agency, under grant number 2014-01411. The study was able to use the facilities and expertise of the full-scale test environment AstaZero through the open research grant, application number A-0025. Here you can find full paper, and for more information contact Fredrick Ekman at Chalmers (fredrick.ekman@chalmers.se) or read his licentiate thesis titled Designing for Appropriate Trust in Automated Vehicles that was publicly presented earlier this year. 

The Day 1 C-ITS Application Green Light Optimal Speed Advisory. Leveraging the growing communication capabilities between vehicles, infrastructure and other road users, applications under the C-ITS umbrella are expected to improve road safety, traffic efficiency and comfort of driving by helping the driver take decisions and adapt to the traffic situation. The Day 1 set of C-ITS applications, as defined by the C-ROADS platform build on mature technologies and are expected to be deployable and provide benefits in the short term, but what scientific evidence is there on their effectiveness and what gaps in knowledge are there? For the C-ITS Day 1 application Green Light Optimal Speed Advisory (GLOSA), these questions were addressed by a systematic mapping study (to our knowledge, the first such study to be published), conducted as part of the Nordic Way 2 project (co-financed by Connecting Europe Facility, CEF project 2016-EU-TM-0051-S), presented at the European Transport Conference 2019 and published in Transportation Research Procedia in 2020. Among the findings where that while there are many published studies evaluating GLOSA, the absolute majority collect data in simulation, focused mainly on observable effects for the equipped vehicle where fuel consumption and travel time were the most prevalent effects examined. Further, there was great variation in the effects observed (for instance, fuel consumption varied from no evident reduction to approximately 70% reduction between studies) providing little consensus in concluding the effectiveness of the GLOSA application. A possible reason for the big effectiveness variation is a lack of well calibrated models used in the simulations scenarios, especially with regard to driver and fellow road user behaviour and precision of traffic light phase shift prognoses. For more information contact Niklas Mellegård at RISE (niklas.mellegard@ri.se).

Making autonomous drive skilled in extreme situations. During 2020 Sentient finalised the development and testing of the S+ Split-μ Control function, that makes autonomous drive safe in the critical situation of braking in an emergency on split friction roads. Compared to traditional ABS, the braking distance could be reduced by up to 37% while maintaining stability. The function is available also for use in manually driven cars to aid the driver perform like expert drivers would in a split-μ situation. Watch this demonstration from the Colmis test track outside of Arjeplog. More information about safety functions developed by Sentient is available at the company’s website.

Ljuddesign som ökar tillit och minskar åksjuka i självkörande bilar. Hur kan ljuddesign höja användarupplevelsen i automatiserade fordon? Denna fråga har Volvo Cars utforskat de senaste två åren tillsammans med RISE och Pole Position Production. Projektet Ljudinteraktion i Intelligenta Bilar har tagit fram helt nya typer av gränssnitt där passageraren får information om bilens kommande beteende, samt vad i trafikmiljön som bilen fokuserar på. Signalerna låter bland annat snarlikt bilens naturliga ljud vid acceleration och fartminskning, men spelas någon sekund innan bilen agerar. Projektets studier har visat att signalerna ökar passagerarnas tillit till bilen, samt minskar åksjuka för en majoritet av passagerarna. I projektets avslutade del implementeras en prototyp av ljudgränssnittet i en Volvobil, vilket gör det möjligt att uppleva ljuden i verklig trafikmiljö. Resultat från projektet kommer presenteras vid ett seminarium hos SAFER i slutet av januari. Hör av er till projektledaren Fredrik Hagman på Volvo Cars för mer info (fredrik.hagman@volvocars.com), eller besök projektets hemsida. Projektet finansieras av Fordonsstrategisk Forskning och Innovation (FFI).

DI-PPP public and private partnership platform for quick and effective implementation of digital transport infrastructure: This pre-study is jointly financed by Drive Sweden and Trafikverket to accelerate the implementation of digital infrastructure in Sweden. The project uses the Trafikverket roadmap on connected and automated road transport system extensively to explore the synergies and to support the service development. The project defines the digital transport infrastructure from a system of systems perspective with the identification of key areas, action points, and expected achievements for the year 2021 – 2025. The project calls for both top-down and bottom-up approaches to build infrastructure that on the one hand enables applications and services fulfilling the mobility needs, and on the other hand, is built on an existing infrastructure with incremental advancement. The project calls for the establishment of a public and private stakeholder partnership platform that is long-term, proactive and progressive, with strong engagement and balanced investments among stakeholders to accelerate the infrastructure implementation. The results have been presented at the Drive Sweden thematic area digital infrastructure, and for more details and reports, please contact Lei Chen at RISE (lei.chen@ri.se).

Project CeViSS. Cloud enhanced Vehicle – intelligent Sensor Sharing (CeViSS) is a joint Drive Sweden project that has run from January to December 2020. The project was financed in part by Vinnova / Drive Sweden with partnership including Carmenta, CEVT, Ericsson, Volvo Cars and Veoneer. The primary goal of the project was to extend the previously established AD Aware Traffic Control cloud with functions to study and demonstrate how the central cloud platform can be used to collect and enhance critical traffic information before safely sharing it between automotive actors. The project successfully demonstrated how data registered by a Veoneer vehicle’s sensors, was collected, analyzed and enhanced in real-time on the central cloud level and then shared with the two project OEM partners; CEVT and Volvo Cars. Their connected cars could then take appropriate action and more precisely mitigate the hazard on their road ahead. The project also showed how the Carmenta Central Traffic Cloud could send instructions to the Veoneer and CEVT cars such as a recommended speed inside geofences (to be used by the Adaptive Cruise Control (ACC)) and search requests to look for specific symbols or texts (e.g., license plate numbers). Tests were also done where the Central Traffic Cloud had direct control of on-board cameras to start sending video when the Veoneer’s test vehicle approached an accident scene. Images or live video from the scene have the potential to give 112 operators and first responders a better understanding of the situation and help dispatch the right resources as well as make a more detailed planning of the rescue operation before arrival. A series of workshops was arranged during the project with representatives from two rescue organisations to get their response on the value of the technology. Both KatastrofMedicinskt Centrum (KMC) and SOS Alarm confirmed that when planning a rescue operation as well as when organizing the work at the scene it is important to collect as much information as possible about the accident area. Images or live video transmitted from a recent accident under strict control have the potential to improve rescue operations. As the sharing of sensor data in such a way have possible privacy concerns, the legal aspects was also investigated. The results of the legal study is documented in a separate report, added as an appendix to this document. The main deliverables from the project were live proof-of-concept trials performed at several occasions with final tests successfully completed at AstaZero test track, October 19, 2020. A film documenting these tests and explaining the project results was produced and a presentation held at a webcasted Drive Sweden event on December 1, 2020 concluded the project. The project has based its work on the cloud-based platform that was created in the project ”AD Aware Traffic Control” and further extended in the project ”AD Aware Traffic Control Emergency vehicles” and the following ”AD Aware Traffic Control – Advanced Cooperative Driver Assistance” project. The project used technology in Drive Sweden Innovation Cloud and its results will be integrated in this innovation platform for future use.

Digital Twins Are Not Monozygotic – Replicating ADAS Testing Across Simulators. Testing in simulators is an essential component in cost-efficient and effective ADAS development. Without countless hours on virtual test tracks, arguing that an ADAS is safe for use on public roads will be practically impossible. However, how can we interpret issues that are detected in a simulator? Would they generalize to the real-world environment? Would they even generalize to another simulator? In a joint study with the University of Luxembourg, RISE used search-based software testing to identify safety violations of a pedestrian detection system in TASS/Siemens PreScan and ESI Pro-SiVIC. However, when replicating the same scenario in the other simulator, the researchers found that the results often differed substantially. Consequently, the researchers recommend future V&V plans to include multiple simulators to support robust simulation-based testing. Make sure the ADAS works safely in other simulators before hitting the real-world roads! The paper pre-print is available here, for more information contact Markus Borg at RISE (markus.borg@ri.se).

Nordic initiative for transport of passengers and goods by drone (NDI): The Nordic countries are joining forces to drive the development of drone transports for both goods and passengers.

The project reference group includes Norwegian Avinor ANS and Finnish ANS. The project is welcoming partners and will collaborate with NEA – the Nordic Network for Electric Aviation to jointly plan for short- and long-haul transports with electric aircraft. For collaborations, please contact Tor Skoglund at RISE (tor.skoglund@ri.se).

Testing safety of intelligent connected vehicles in open and mixed road environment (ICV-Safe): This project is a bilateral joint effort to identify safety-critical scenarios and to develop risk assessment and mitigation methods for intelligent connected vehicles (ICVs) by taking advantage of the large-scale open connected test environment in Shanghai. The project will conduct iterative case design, data collection, simulation, and open road test. The results will lay a foundation for the safe introduction of ICVs to minimize safety risks. RISE is coordinating the Swedish part with partners including Chalmers University of Technology, Alkit Communications AB, WSP AB, and FellowBot AB. The Chinese part is coordinated by Tongji University with partners including Research Institute of Highway (RIOH) Ministry of Transport, Chang’an University, Guangzhou O.CN International Technology Co., Ltd, Shanghai SongHong Intelligent Automotive Technology Co., Ltd., and Beijing Tusen Weilai Technology Co., Ltd (TuSimple). Through the project, the partners are also working actively with Swedish actors in China outside the project consortium to explore synergies for further research collaborations and innovation.

CTS – Heterogeneous project. This project aims to investigate effects of autonomous vehicle in a mixed traffic environment, i.e., the traffic where automated vehicles share roads with different types of manually-driven vehicles. Effects on traffic flow and safety are the main interests of the project. An example of upcoming activities in the project is a driving simulation study, which is planned during January-February 2021. The study aims to investigate whether there is a behavior adaptation among human drivers when they share roads with automated vehicles. This project is funded by VINNOVA, and it is within the scope of CTS (The China Sweden Research Centre for Traffic Safety), which is an on-going collaboration within SAFER’s research program. Partners on the Swedish consortium includes VTI, Chalmers, Volvo Cars, and Volvo Group; and partners on the Chinese consortium are RIOH, Beijing Jingwei HiRain, Tsinghua University, and Tongji University. Link: Heterogeneous Traffic Groups Cooperative Driving Behaviours Research under Mixed Traffic Condition | SAFER – Vehicle and Traffic Safety Centre at Chalmers (saferresearch.com).

Drivers’ ability to engage in a non-driving related task while in automated driving mode in real traffic. Engaging in non-driving related tasks (NDRTs) while driving can be considered distracting and safety detrimental. However, with the introduction of highly automated driving systems that relieve drivers from driving, more NDRTs will be feasible. In fact, many car manufacturers emphasize that one of the main advantages with automated cars is that it “frees up time” for other activities while on the move. This paper investigates how well drivers are able to engage in an NDRT while in automated driving mode (i.e., SAE Level 4) in real traffic, via a Wizard of Oz platform. The NDRT was designed to be visually and cognitively demanding and require manual interaction. The results show that the drivers’ attention to a great extent shifted from the road ahead towards the NDRT. Participants could perform the NDRT equally well as when in an office (e.g. correct answers, time to completion), showing that the performance did not deteriorate when in the automated vehicle. Yet, many participants indicated that they noted and reacted to environmental changes and sudden changes in vehicle motion. Participants were also surprised by their own ability to, with ease, disconnect from driving. The presented study extends previous research by identifying that drivers to a high extent are able to engage in an NDRT while in automated mode in real traffic. This is promising for future of automated cars ability to “free up time” and enable drivers to engage in non-driving related activities. The study was conducted by Volvo Cars and RISE in collaboration between two FFI funded projects: TIC – Trust to Intelligent Cars and HARMONISE – Safe interaction with different levels of automation. A pre-print of the paper is available here, and for more information contact Jonas Andersson at RISE (jonas.andersson@ri.se). 

Remote Driving Operation (REDO) project. Remote driving operation or teleoperated driving can support deployment, operation, and testing of automated vehicles. With advancement in wireless communication technology, this has recently becomes more feasible. In the REDO project, we are looking at different technical and non-technical aspects related to teleoperated driving, which include 1) interaction with remote operator; 2) feedback mode from vehicle to remote operator; 3) system architecture; and 4) laws and regulations. Demonstration is also planned towards the end of the project. This is a 3-year project funded by VINNOVA. The partners in the project are: VTI, CEVT, Einride, Ericsson, Ictech, KTH, NEVS, and Voysys. Link: REmote Driving Operation – REDO | Vinnova.

Human factors in remote operation of heavy vehicles. Currently, most highly automated vehicles still require the presence of a human safety operator in the vehicle, and it is evident that automated driving without human “fallback” might be distant. On the other hand, having a human operator in the vehicle jeopardizes major anticipated benefits of automated driving – productivity. This is especially evident when it comes to heavy automated vehicles. To bridge this gap, stakeholders are exploring teleoperations technology, which enables highly automated vehicles to be remotely operated if necessary. But remote operation comes with its own challenges, both from technical and human behavior perspectives. In this SAFER co-financed prestudy, Scania and RISE have identified potential safety challenges and research gaps related to human behavior in the context of remote operation of heavy automated vehicles. A general view of the human factors related challenges within the remote operation topic can be summarized by highlighting phenomena such as physical and psychological distancing, screen delays, network latency delays, inefficient interface designs, and human operator’s cognitive limitations. These are not exclusive to one single operational level, or application type, and are often interrelated. A larger body of scientific work can be found related to human factors in remote operation in other domains (e.g., robotics, aerial drones, military). Some of the findings from these domains can have value for the automotive domain, however, generally design requirements are not directly transferable between domains as there are domain specific challenges. An overall conclusion from the prestudy is that human factors in remote operation of highly automated road vehicles have been somewhat neglected by industry and research community. By providing an overall conceptualization of remote operation and its complexity, a theoretical framework, a state of the art overview, and a list of gaps and challenges, the expectation is that this pre-study will stimulate more activities in the area. The recently started FFI-project HAVOC is example of such an activity. The pre study was co-financed by SAFER and conducted by Scania and RISE.

Task Force – Hygiene procedures in test with research persons. Since the rapid outbreak and continued global spread of the Coronavirus Disease (COVID-19) in 2020, aspects of much of our day-to-day life in society has been impacted – our workplaces are no exception. Due to the novelty of COVID-19 to health officials in Sweden and around the world, standardized guidelines on how to safely proceed with business activities that require the sharing of physical spaces and/or equipment between individuals has yet to be established. In anticipation of this pandemic being an ongoing issue, a task force was assembled to help address this gap. The SAFER task force was comprised of transport industry professionals in Sweden that have a role in conducting research and testing that would currently be deemed to place individuals at risk of contracting the virus if one of the involved actors were to be an active carrier of the virus. Therefore, the goal of this task force was to help establish a set of general guidelines to consider when attempting to mitigate the risk of contagion while performing research or testing activities at our respective corporate facilities. Questions related to “How can experiments involving test persons in vehicles, driving simulators, virtual-reality studios, or similar test facilities continue?”, “What safety procedures should we consider to introduce in order to ensure proper hygiene for the individuals involved?”, “Is it required for drivers to wear a face mask?”, and “How do we implement physical distancing provisions pre- and post-experiment interviews?” were addressed. Partners in the Task Force were VTI (coordinator), Volvo Group Trucks Technology, Autoliv, Veoneer, RISE and Scania. The project was co-financed by SAFER.

Europeiska kollektiv-tester igång

Efter att ha tappat visst momentum under pandemins första våg har nu nyheter om tester med självkörande fordon för kollektiva transporter börjat trilla in igen.

På Djurgården i Stockholm har Keolis, Urban ICT Arena, Telia, Ericsson Intel och T-engineering precis börjat rulla publika tester med fordon som kopplas mot kontolltorn med 5G [1, 2]. Syftet med testet är att i en nära framtid kunna erbjuda säkra transporter med förare utanför fordonet. Testerna är en del av det pågående jätteprojektet SHOW i vilket RISE samordnar de svenska testsiterna.

Ett annat exempel hittar vi i Brașov i Rumänien, där det meddelas om ny satsning på test av självkörande fordon [3].

Egen kommentar

Efterfrågan på kollektiva persontransporter gick ned i spåren av pandemin och trafikbolag har haft det tufft. Att bolagen fortfarande visar på kraft nog för att fortsätta utvecklingen mot självkörande transporter är glädjande och pekar på att just de aktörerna tror extra mycket på teknikens potential.
