Car Car Warning Simulation And Evaluation

Rear-end accidents occur frequently on the basic sections of freeway.and cause serious losses.To research rear-end collision warning when driving with the car-following on the basic sections of highway.and to evaluate the safety of driving. will be able to effectively prevent and reduce rear-end accidents.And it can improve the safety of high-speed driving with the car-following and provide a theoretical basis for speed control.And it will bring in far-reaching significance for people's lives and property. Meanwhile.the research results will be directly applied to evaluate the safety of driver behavior and provide reference for the development of the driving simulation safety detection system.First of all.the paper analyzes the influential factors of the behavior with the car-following on the highway.from the perspective of the driver characteristics, vehicle characteristics.road characteristics and traffic flow characteristics.Then it establishes the critical safey distance model,the basic safety disdance model and the ideal safety distance model under nine states.which base on the analysis to the safety of driving and the classical theory of Newtonian mechanics.And it also uses the calibration value of the relevant factors to simplified the rear-end collision warning model.Meanwhile,it establishes the safety evaluation model of the driver based on the safety distance model.Finally,the paper studys the process and methods of rear-end collision warning simulation.and determine a practical program of the rear-end collision warning and safety evaluation of the driver. Then to validate the effectiveness of the rear-end collision warning model and safety evaluation model of the driver by using driving simulation system.The results show that the speed control of the driver is the main factors which affect safety of the driving.Meanwhile.the main factors which affect rear-end collision warning model are the model coefficients.To select the correct and reasonable model coefficients,and to determine effective rear-end collision warning program.also to suppress and correct the alarm.are the basis which warn effectively to the rear-end collision and evaluate to safety of the driving.Driving simulation results show that the rear-end collision warning model and safety evaluation model are effective and reliable.can be used to test safety of the driver behavior with the car-following.
