Intersection assistant

A driver’s miscalculation of speed and distance or failure to stop at red lights or “Stop” signs are common causes of accidents at intersections.

The “intersection assistant” recognizes this type of critical situation at intersections and warns the driver of red light infringements or hazardous turn-off maneuvers. The system can also recommend the right speed for a green traffic light wave or when approaching a red traffic light.

At crossroads, the “intersection assistant” supports the driver by direct communication between the vehicle and the traffic signals. Camera systems installed at the intersection monitor the traffic situation and send this information together with the signal times to the vehicle via wireless technology. The system evaluates the data received together with onboard information from the vehicle such as speed, distance from the intersection and direction of movement.  

Appropriate traffic infrastructure equipment and links between the infrastructure and vehicle communication technology offer potential for enhancing traffic safety further. The driver always retains responsibility for the vehicle and is offered support in hazardous situations from the “intersection assistant”.
