Heterogeneous Traffic Simulation for Urban Streets Using Cellular Automata

This paper aims to develop a simulation model for heterogeneous traffic using cellular automata (CA). A detailed description of the developed CA model used to simulate heterogeneous traffic is presented. Heterogeneous traffic comprises of vehicles of different static and dynamic characteristics. Therefore, the developed model should be capable enough to include the characteristics of different types of vehicles. The results of simulation depict that not only the model includes heterogeneous traffic characteristics but real traffic behavior is also taken care of. The developed model is calibrated and validated using distance headway-speed relationship obtained from field data.
