DLR tests Car2X communication in real traffic

– DLR is testing automated driving in the MAVEN project.
– Cooperative automated vehicles cross signalised intersections in Braunschweig.

The Institute for Transportation Systems of the German Aerospace Center (DLR) will be testing the crossing of a traffic light intersection with cooperative automated vehicles in Braunschweig in the beginning of October 2018 in the MAVEN (Managing Automated Vehicles Enhances Network) project. For this purpose, the antennas and measuring equipment already installed in connection with the application platform Intelligent Mobility (AIM) at the traffic lights at Tostmannplatz in Braunschweig will be used.

Communication between car and traffic light

One of the most important aspects of cooperative automated driving is the communication between equipped vehicles and the infrastructure (Car2X communication), such as traffic lights. “In the future, the road infrastructure must know at where road users move on intersections. Then it can optimally coordinate these movements – like a conductor in the orchestra,” explains Julian Schindler from the DLR Institute of Transportation Systems. The infrastructure installed at Tostmannplatz uses a camera to detect pedestrians and cyclists and transmits this information to automated vehicles for more precise and early detection. The security increases. In addition, the traffic lights provide speed and lane change recommendations to the vehicles.

New technique for testing with platoons

Within the EU project MAVEN, this technique has already been prototypically implemented on a test site, as can be seen in the video below (note that there is no sound):

The AGLOSA traffic control system shown in the video uses a new concept of integrating the traffic simulator SUMO into the controller and is further described in Deliverable 4.1 Cooperative adaptive traffic light with automated vehicles.

From the beginning of October, these will now be tested in real traffic. In addition to the existing technology of the Application Platform Intelligent Mobility (AIM), the traffic lights at Tostmannplatz will be equipped with additional measuring technology. A camera mounted on the light pole records anonymised data. Mobile cameras owned by the Institute support the results of the new camera scientifically in the beginning. The camera data is used to help the vehicles to “see around the corner”. Furthermore, automated vehicles are creating so called platoons which allow a close following. By doing so, automated vehicles can travel across the intersection with less distance to each other, so that more vehicles pass the traffic light during the green phase and the traffic lights are thus more effective. As a further development to the more well-known truck convoys that are currently being tested on freeways worldwide, the urban platoons from MAVEN focus on rapid adaptability to the environment, especially taking into account all non-automated road users. Platoons will constantly form and dissolve without restricting the behavior of other road users.

MAVEN at ITS World congress and Big Data Expo

The week of 17-21st of September was a busy week for the MAVEN consortium when it came to dissemination. First of all the project was present at the year ITS World congress with several papers. Xiaoyun Zhang presented papers about cooperative queue data for adaptive traffic control and a joint paper with the XCycle project about green waves with speed advice. At the exhibition area people could of course come to the stands of the consortium partners for more information on MAVEN. Apart from presentations and exhibitions, the congress is of course also about informally meeting stakeholders who are active in the field. With this we noticed a high interest in our work on extended message sets as reported in D5.1, which is a signal that the impact of the MAVEN work is increasing.

 At the same time the Big Data Expo took place in Utrecht, the Netherlands. This event is organized for the rapidly growing field of data science and was attended by a large and varied group of the general public. The presentation given by Robbin Blokpoel focused on the AI and data aspects of traffic management and automated vehicles in specific. It was attended by over 150 people and received a lot of positive feedback. In conclusion it was a great experience to introduce the potential of automated driving and the innovative potential of MAVEN to a wider public.

Successful field tests in Helmond

The MAVEN team has successfully tested the integration of the traffic control algorithms with the vehicle message extensions at the Helmond site. The tests were already performed in simulation, as was demonstrated here. However, a real world environment can always introduce unexpected challenges. Therefore, a cooperative vehicle was upgraded to support the MAVEN standards and seven test runs were executed to observe the behaviour in the real-world. Even though no extra priority was granted to the vehicle, positive effects could be observed at the controller in three test runs that could be attributed to the extra information provided by the MAVEN vehicle.

The team on site also made a VLOG video to share their experience:

In summary this was a very successful event and the project is looking forward to the next test event in February when the automated vehicle from Hyundai will test all field use cases of Helmond!

Save the date: MAVEN workshop – 24/10/18 in Greenwich, London

The next MAVEN stakeholder workshop targeting local authorities will take place in Greenwich (London) on 24 October 2018.

The workshop’s aims are to:

  • explore in more detail how increasingly instrumented vehicles are likely to behave on urban roads and how this may affect the traffic management task and wider transport goals
  • provide insight to the role that communication technology can play in the shorter-term of connected transport and the longer-term of automated transport
  • promote reflection among local authorities on their traffic management role and responsibility as CCAV evolves
  • get your input on the traffic management policies the MAVEN project will evaluate in its final phase

Local authorities are the main target group of this workshop; however, it is also open to other urban transport stakeholders with an interest in CCAV. A small budget to help cover the travel expense of local authority representatives is available.

The draft agenda will be available soon. Meanwhile, online registration can be found here.

EC publishes its plans regarding connected and automated mobility

The recently launched Third Mobility Package of the European Commssion includes a communication on connected on automated mobility.

 

The communication sets out the EC’s agenda for connected and automated mobility, which is essentially about building an apt legal framework with due regard for ethics and society and providing financial support to move this agenda forward. While it acknowledges the importance of automation to address safety and to keep the EU’s automotive industry competitive, it stresses the need for automated vehicles to deliver new, cost-effective services that are integrated into the transport system and support social inclusion. The communication is very relevant to the MAVEN project as it covers many integration issues such as the link between automated vehicles and traffic management and infrastructure and it asserts the need for connectivity, including C-ITS, to enable automation.

The communication proposes many actions to be taken including:

  • Regulation of platooning under the revision of the General Safety Regulation for motor vehicles
  • Regulation related to safe and trusted communications between vehicles and the infrastructure, which complies with the General Data Protection Regulation
  • Consider the need for specifications, under the ITS Directive, for access to in-vehicle data by public authorities to support the traffic management task.
  • Intensifying coordination with Member States on traffic rules to ensure they are fit for automated vehicles
  • The development of guidelines to ensure a harmonised approach for national ad-hoc vehicle safety assessments of automated vehicles
  • Kicking off a process of building a new approach for vehicle safety certification for automated vehicles
  • Regulation of data recorders for automated vehicles to clarify who was ‘driving’ in case of an incident

Milestones for V2X communications reached and presented at ETSI ITS workshop

MAVEN has developed V2X communication schemes and message sets for infrastructure-assisted automated driving. For the cooperative infrastructure, an I2V Lane Change Advisory service and a dedicated profiling of the SPaT (Signal Phase and Time) and MAP (topology) for lane-specific GLOSA were developed. For the cooperative automated vehicles, extensions of standard CAM (Cooperative Awareness Message) messages have been designed to allow interaction with cooperative intersections and to support management and control of platoons. Finally, the currently under standardization Collective Perception service has been adapted to the needs of MAVEN to support the applications of cooperative and automated vehicles aimed at increasing the safety of VRUs (Vulnerable Road Users) and vehicle drivers. The developed schemes are backward compatible as required by the car industry and to foster their future deployment. They are provided in terms of ASN.1 (Abstract Syntax Notation One) definitions and detailed message data specifications that can be openly accessed. The aforementioned communication schemes have been tested in small test benches aimed at evaluating the technical functionality of the developed solutions from a communication point of view, and hence their suitability for integration in infrastructure and vehicle prototypes. MAVEN has actively contributed to the European ETSI standardisation in this area, especially for the collective perception definitions. All the aforementioned communications schemes were presented at the 2018 ETSI ITS Workshop: http://www.etsi.org/news-events/events/1234-etsi-its-workshop-2018

Vehicle milestones for communication and platooning reached

MAVEN has completed vehicle automation developments, which allow the reception of Signal Phase and Timing (SPaT) messages from the infrastructure. The vehicle automation takes the desired speed sent by the Road Side Unit (RSU) for the upcoming traffic light into account when planning the correct behavior. As the MAVEN vehicle is longitudinally and laterally automated at the end, the vehicle reaches the green light fluently or comes to a smooth stop when passing at green is not possible.

For platooning a set of four state machineshas been developed. These state machines have been implemented in the vehicle automation to proof if the MAVEN urban platooning concept is working as desired. The image shows the state machines and the related behavior of an automated vehicle when reaching another automated vehicle able to form a platoon on the road. The working principle is illustrated in the figure below:

While driving, the cooperative ego vehicle on the left receives information about a cooperative vehicle in front which is also able to form a platoon (1).  This information includes position, velocity, acceleration and also planned behavior on the upcoming intersection (turning/going straight). After processing this data in the platooning logic, the ego vehicle decides to form a platoon (2). Now it communicates this to the vehicle ahead, which receives this information, accepts and provides detailed trajectory information to the follower. Hence, the ego vehicle adapts its velocity in order to close the gap (3). When the gap is closed, the initialization is done and the vehicles follow each other in a platoon (4). The following vehicle is always in charge of choosing an appropriate distance. If the follower does not trust the leader, or recognizes any other thread, it can immediately stop platooning.
