Improving Vehicular Traffic Simulations Using Real-Time Information on Environmental Conditions

This contribution illustrates the benefit of incorporating real-time environmental data into highway traffic information systems and describes the modelling and integration of weather conditions into a complex microscopic traffic simulation. Using stationary measured weather data as an example, the achieved results show the potential extended Floating Car Data (xFCD) - submitted to the traffic information system by cellular communication-can have for traffic simulation. Therefore, an estimation about the expected communication network load is given, when xFCD equipped vehicles have become prevalent.
