Network Resource Usage of the German Toll System: Lessons from a Realistic Simulation Model

We are using a detailed realistic discrete event simulation model of the automatic German toll system to study resource usage of the mobile data network for various system configurations. Starting with an existing simulation model [1] we describe the driving patterns used in the simulation and the functionality added to the simulation model. Next we explain enhancements in simulation performance implemented to reach simulation runs covering 16 weeks of simulation time for a vehicle fleet of 700.000 heavy trucks. Using the simulation model we analyze the number of simultaneous mobile data network connections which is strongly affected by a single system parameter. The realistic configuration is used to study the speed of rolling out map data updates across the vehicle fleet.
