There are two data streams:
Data stream 1: Roadside units send data such as the location of the road works to the traffic information centre. This information is made available to service providers who offer related services to drivers over the mobile network. This service is provided using the "connected track"
Data stream 2: From the roadside, the new WiFi-P communications technology is used to send road works information directly to vehicles fitted with compatible receivers. This form of communications is known as "cooperative".
Advantages of this service:
- Both road users and road managers receive information about the exact location of the road works.
- Information reaches road users more quickly over the secure WiFi-P connection than over the existing mobile networks.
- The additional in-car warnings provide greater safety on the road, also for road workers and road inspectors.
- Better information will improve the traffic flow and reduce the number of collisions at road works.
