Implementing the Intelligent Driver Model in a physical vehicle simulator

Abstract

The Intelligent Driver Model was introduced in 2000 by M. Treiber et al. as a mathematical car following model for traffic micro- simulation. It is an obvious question whether this model is applicable in physical vehicle simulator, which would be a big step forward a real application. Of course, it is also essential that the model can be applied to the description of real traffic conditions - thus also to take into account the real speed-density relationship [10]. In the present work this model is implemented in the CARLA physical vehicle simulator. First the simulators acceleration-control functions are established. These functions give the amount of throttle or brake control values to achieve the desired acceleration. Having these functions the Intelligent Driver Model is implemented and tested with simple simulation experiments.
