Safety Following Space Modeling and Speed Control on Highway

Abstract:

Due to the rapid development of economics and society, China has witnessed increasing highway accidents, especially rear end collisions that mainly caused by over-speeding or too close following distance. Based on the vehicle dynamic analysis, therefore, a 3 step-based safety following space identification model according to Mazda vehicle is proposed to describe the brake performance and three driving states are taken into considering, including total following state, part following state, and three-kind extreme states. Then, a self-adaptive fuzzy reasoning model is used to control the traveling speed so as to adjust the traffic flow as smoothly as possible. The Matlab simulation results shows this proposed fuzzy control model helps minimize the occurrence probability of rear-end collision on highway and improve the overall traffic safety performance and management level.
