Simulation of Mixed Traffic Flow within Intersection

Abstract

Although many studies have targeted homogeneous and heterogeneous traffic flow, they are normally little or no attention to driver reaction passing intersection. Understanding complex movement within an intersection is the critical task which can explain the reason of traffic jam especially in big cities (for example, Ho Chi Minh City, Hanoi). This paper describes a microscopic model based on Cellular Automata (CA) for mixed traffic flow and is concerned with how the driver interacting with other vehicles in the intersection. A simulation environment is also built with a set of basic rules integrated to handle the way vehicle passing an intersection. Given an O/D matrix, the simulation results present a strong relation between traffic and control parameters even with the given set of rules. Based on this research, further studies can be performed easily in order to understand the heterogeneous 2-wheel dominated traffic.
