Warning drivers about vehicle wrong way ahead over Nordic Way interchange and cellular network

Abstract

Meeting vehicles in wrong direction on a divided highway is a dangerous situation that might cause a high energy collision. If one can warn other drivers that a vehicle is heading in their direction using C-ITS, this will help the drivers to avoid the situation. Testing if this can be possible with today’s available technology with existing cellular network and the Nordic Way interchange architecture is therefor of interest. To test this, a simplified C-ITS system has been developed and tested on a divided highway to gather important metrics for warning drivers about wrong way drivers. The results show the possibility that vehicles can report their position to a backend service, that can detect if a vehicle drives wrong way and publish this to an interchange node and finally, other backend services can then publish a warning to other vehicles within a time delay that is low enough for other drivers to react.
