Network Topology Effects of Road Traffic Models

In order to evaluate the performance of cooperative automatic vehicles (CAVs) that interact wirelessly, researchers use two types of simulators: microscopic traffic simulators and network simulators. While the former simulate the movement of vehicles on a road network, the latter simulate the wireless communication between vehicles. Much attention has been paid to the precise modeling of wireless communication because of its obvious importance for the accuracy of the simulation results. As well, much attention has been paid to precise modeling of road traffic, though mostly for the purpose of traffic engineering. Much less attention, however, has been paid to the impact of the road traffic model on the simulation results for CAV simulations.

Goals of the thesis

This thesis will investigate the impact of different road traffic models on the simulation results of CAV simulations. For this, mobility traces will be generated by a variety of road traffic simulators, including SUMO and CityMoS. This entails the modeling of a road network, the generation of traffic flows, and the simulation of the movement of vehicles. These traces will then be fed to a wireless network simulator, specifically the OMNeT++ INET Framework. From the simulation results, various metrics will be derived, both in terms of road traffic and wireless communication as well as those specific to CAVs. A comparison of the simulation results will reveal the impact of the road traffic model on the simulation results.
