TLEX successfully used in Concorda test

The first CONCORDA test week took place from 2-6 September 2019 in the Metropolitan Region of Amsterdam.

Hereto, the local project’s partners – FCA-CRF, NXP and The Amsterdam Practical Trial- tested the information exchange between test cars and road infrastructure to support the self-driving task of vehicles.

Testing information transmission

Therefore, the partners used different communication techniques (hybrid) in various traffic situations. First of all, they tested the time needed for information transmission and data status when they reach the car from smart traffic lights or roadworks. Secondly, for cellular/cloud communication, the partners used TLEX to connect the road infrastructure with vehicles.

Collecting valuable data

The event successfully allowed the consortium to collect valuable data for further simulations and analysis. Based on this input, they can identify the aspects that they want to refine for the second test week this fall.

Additionally, the partners will expand the test area to highways A5 and A9 and the city centre of Amsterdam (urban road). For the expanded test, they will also connect the road infrastructure on the A5 and A9 to TLEX.

Enabling traffic data exchange internationally

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.


CONCORDA is a public-private, co-financed, large-scale cross-border project. It aims to pre-test 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.
