Cellular automata models for traffic movement assume that vehicles are particles without routes. However, if one is interested in analysing microscopic properties, it is necessary to assign a route to each trip. This paper discusses the latest developments in the ITSUMO traffic simulator. These developments aim at modeling more sophisticated drivers' behaviors such as en-route decision-making. They were tested in two scenarios, one being a real-world traffic network. We extensively discuss the effects of the use of various routing algorithms, as well as ration demand/capacity, control measures, network topologies, and re-planning strategies. © ECMS.
