Vehicle Motion Simulation Method in Urban Traffic Scene

Abstract

Vehicle motion simulation is an important part of traffic scene simulation, which is helpful for urban road planning and design, road capacity testing and other applications. Based on the characteristics of urban traffic scene, this paper studies the vehicle’s movement behavior. On the basis of the intelligent car following model based on safe distance, an improved car following model is constructed by adding acceleration adjustment items which is suitable for real urban traffic scene. Besides, an improved vehicle lane change model is construct on the basis of two-lane change model based on acceleration analysis. Experiments show that the two vehicle motion models proposed in this paper are effective in simulating vehicle stop, start and lane change in urban traffic scene.
