Questions tagged [traffic-simulation]

Traffic simulation are an approximate imitation of traffic flow behavior on any road network.

The components or features that are part of traffic simulations are i) Traffic behavior (homogeneous or heterogeneous), ii) traffic flow models (microscopic, macroscopic or mesoscopic), iii) traffic models (such as car following, lane changing) and iv) system (discrete or continuous).
