Linking roadside units and iTLCs with test vehicles
The Dutch CONCORDA project partners, FCA-CRF, NXP and The Amsterdam Practical Trial, are testing the information exchange between test cars and road infrastructure to support cars’ self-driving tasks. The partners use different communication techniques (hybrid) in various traffic situations to test the time needed for information transmission. They also test the data status when they reach the car from smart traffic lights or road works. Both for cellular and cloud communication, TLEX connects the road infrastructure with vehicles.
Minimum latency and maximum security
Monotch consecutively created direct links with roadside units and traffic light controllers and made the data communication available in ETSI via IF2 interface for service providers NXP and V-Tron. Furthermore, they converted messages to ETSI and made the infrastructure-to-vehicle communication safe, fast, easy to monitor and available with governance data.
The plug-and-play character of TLEX proved its value, enabling connected service providers to get access to the data well within the deadlines and, even more importantly, with a minimum of latency and a maximum of security.
During the first CONCORDA test week from 2-6 September 2019 in the Metropolitan Region of Amsterdam, the technology was successfully tested. This allowed the consortium to collect valuable data for further simulations and analysis, because it identified the aspects to be refined for a second test week. The test area will be expanded to highways A5 and A9 and the city centre of Amsterdam (urban road). For the expanded test, the road infrastructure on the A5 and A will also be connected to TLEX.
CONCORDA is a public-private, co-financed, large-scale cross-border project aimed at pre-testing the employment of connected and automated driving on highways and within (inter)urban environments. CONCORDA is preparing Europe for automated driving and truck platooning, requiring smart vehicles and high-quality digital road infrastructure.
The communication technology to enable the exchange between autonomous vehicles and road infrastructure is tested in CONCORDA pilots in Belgium, Germany, France, the Netherlands and Spain. The tests occur not only on the highway but also on provincial roads and roads in the urban areas of Amsterdam.
