Traffic Flow Simulation Based on Cellular Automaton Model Considering Driving Mode

Abstract

In order to solve the traffic congestion problem, the characters of traffic should be investigated. Cellular Automaton (CA) models based on brake light rule (BL) can reproduce the three-phase traffic flow. However, all BL models assume that all drivers have the same driving mode. In fact, vehicles can be divided into three types: aggressive, normal and timid. The influence of driving modes on flux is analyzed based on the Tian model, which is a typical BL model. Simulation results show that when adopting different driving modes, the modified Tian model can still reproduce the three-phase traffic flow. In addition, more aggressive vehicles can increase the flux, while more timid vehicles will decrease the flux.
