Development and calibration of a single lane urban traffic simulator

The research presented in this paper is focused on development of a microscopic single lane urban traffic simulator able to reflect real traffic situations. Modeling of the real traffic stream in urban environment is done in Matlab. The model integrates infrastructural submodel and general acceleration submodel. It controls three sets of inlet parameters and covers two primary vehicle conditions, several secondary vehicle conditions and so called emergency condition. Vehicle acceleration, speed, traveled distance and intervehicle spacing are basic output parameters of the model. They are obtained as a result of simulation of real traffic stream in urban environment. In order to bring the model closer to the real traffic conditions, it is calibrated with experimentally gathered urban traffic data. At the end of this process we have obtained flexible single lane urban traffic simulator capable of performing real simulations of traffic flow on different types of arterial roads.
