Integrated simulation of microscopic traffic flow and vehicle dynamics

This paper demonstrates a method for integrating microscopic traffic simulation and vehicle dynamics simulation using Simulation of Urban MObility (SUMO) and IPG CarMaker. The goal is to combine the specific strength of both types of tools and this goal is achieved using the Simulink interfaces that are available for both simulation tools. Two use-cases are presented to demonstrate these strengths and the potential of an integrated simulation of microscopic traffic flow and vehicle dynamics. In the first use case, the detailed vehicle dynamics simulation is used on a road stretch with high curvature to determine maximum speeds along the road. These speeds are afterwards transferred into the network of traffic flow simulation to achieve more realistic speed distributions. Within the second use case, the integrated simulation is used in order to test the detailed model of an automatic cruise control system with surrounding traffic that shows stochastic behavior and does not rely on deterministic maneuver planning.
