Speakers from the UK and The Netherlands outlined the latest developments and innovations in both countries. The seminar was moderated by Tom van Dam, Connekt/ITS Netherlands because we were on Dutch soil at the Dutch Embassy in London.
Simon Smits (Dutch Ambassador in the UK) welcomed those present and indicated that autonomous vehicles are (part of the) answer for traffic jams and pollution.
Andy Graham (White Willow Consulting & the ITS (UK) CAV Forum) mentioned some solutions and challenges concerning CAV. Focus has been on improving engine emissions, tyres, brakes and asphalt. White Willow is making progress in the field of smart parking. They use sensors to know where parking slots are. We are making parking easier and easier to pay.
Challenges are to be met in the field of making use of road data. Road data from both new and older cars should be treated as the valuable data it is.
Martijn Schut (Siemens) reacted to the topic of The verification of Connected and Autonomous Vehicles using digital twins in massive simulation environments. The challenge is the need of a robust methodology, not only for developing, validating and releasing the vehicle, but also for monitoring, maintaining and improving vehicles as a part of a complete ecosystem. Digital twins are an absolute must to carry out the simulations necessary to test the cav. Schut: “We make a digital twin out of everything, from pedestrian behavior in various countries to driver behavior.”
Once tests in the virtual environment have been passed, testing in the real environment can start.
Gavin Jackman (Aimsum, a Siemens Company) dealt with the subject of Autonomous Vehicles and the use of the road network. Aimsum was involved in several CAV projects.
• AV appear to provide more benefits in congested situations such as complex merges and accidents event at low penetration rates, due to reduced headways and faster reaction times.
• There is a reduction of up to 8% in CO2 and NOx emissions, when AV penetration rates reach 100%.
• Delays caused by an accident can significantly be reduced with high AV penetration rates, achieving up to 35% reduction in delay time.
Harm Jan Mostert (Province of Noord Holland, the Netherlands) explains about experiences with CAV projects in this region. The Noord Holland region experiences a lot of traffic congestion, even with bicycles. The province has done several useful studies, tests and pilots to learn more about our role in the mobility transition.
Important results were found concerning Cooperative Adaptive Cruise Control (CACC). CACC was tested in a normal traffic situations on two existing roads, including the interrelationship with the behavior of other cars. ACC is not efficient enough now. A 100% penetration rate of CACC will lead to 11% more efficiency. If the penetration level of CACC is 50% there will be no benefits because of the other drivers without Advanced Driver Assistance Systems.
The next challenge is the necessary standardization of new interfaces. Cooperation is crucial to create system optimization.
Chris Maydom (Intelligent Mobility Consultant) took us into the subject of Human Drive and FLOURISH: Cyber Security for CAV’s. Why is cyber security so important? Vehicles are becoming increasingly connected. Cars are connected to the internet, in-vehicle devices etc. Increased connectivity is likely to be key to the development of CAV. Potential hackers can access the CAV. Cyber threats are becoming more sophisticated. The potential harm from a cyber-attack increases a lot with the introduction of CAVs. “Cyber security is a relatively new thing for cars to worry about. This opens up new risks.” Maydom describes several projects in this field, such as FLOURISH and HumanDrive.
We look back on a very informative and useful afternoon. We thank the Dutch embassy in London for the hospitable reception. The return of this seminar will be in January or February 2020 in the Hague, the Netherlands.
