Different methods and techniques can be used to document the volume and flow of traffic. Induction loops and stationary sensors are used to monitor well-known critical sections or traffic hubs/junctions; data can be collected from cars on particularly busy roads and manual counts can be used to survey temporarily interesting points in the traffic network.
It makes sense to supplement these methods by video systems, developed by Fraunhofer Mobility. Whether they are used in stationary or mobile applications, they are easy to install. In addition to the traffic volume and classification of vehicles, these systems are also able to measure speeds and the length of traffic tailbacks at busy traffic hubs/junctions.
Using all the gathered data, Fraunhofer Mobility makes forecasts for other parts of the transport network and develops the necessary models.
