The Influence Of Vehicle Body’s Color To The Traffic Safety In Rainy Days

Vision is the main means for drivers to obtain information. The color information is the most important part for drivers. The most serious interference for drivers is from vision in rainy days. In rainy days, a variety of adverse conditions to the traffic occur at the same time. It increases the probability of traffic accidents.This paper analyzes the influence of color, driver discrimination and rains on the traffic safety. It also researches the influence of accident mechanism and vehicle body’s color on traffic safety in rainy days. It introduces model of safety distance and safety speed for driving in rainy days. From the perspective of the driver’s response characteristics, it analyzes static cars in rainy days. Because static cars is kind of factor to influence traffic safety in road system. The response result, which is L1(the distance between horn-point and obstacle cars), L2(the distance between brake-point and obstacle cars) and v (vehicle speed through the stationary car), is output by the means of vehicle body’s color to stimulate driver-car system and the response of the driver-car system.Through the actual investigation, the white cars, black cars and red cars is more than other cars. Regarding response result(L1,L2and v) as experiment purpose, the experiment design is scientific and reasonable, eliminate other interference factors. The cars of the white, black and red as research objects. Simulation lab is carried out in a light rain, a moderate rain and a heavy rain.Through processing experimental data, it analyses variation range and trend of L1, L2and v in a light rain, a moderate rain and a heavy rain comparatively. The regression curve of L1and L2about V is drawn and the quadratic function model of L1and L2about V is built for different obstacles in rainy days. The expression of L1and L2will be written according to the summary of the quadratic function parameters in different conditions. Combining the analysis of safety speed and safety distance, the Contrast model on traffic safety for cars of different color in rainy days will be confirmed.
