Analysis of Driver's Physiological Characteristics under Ice-snow Conditions Base on Driving Simulator

In road traffic circumstance, the ice-snow pavement brings obvious adverse influence to the motor vehicles safety. This paper analyzes the relationships between friction coefficient and temperature, and between friction coefficient and relative humidity, and between friction coefficient and thickness, and between friction coefficient and compaction degree through a large number of experimental. Then base on these fundamental analyses, to use the experimental methods which are composed by simulations and actual test, to analyze the influence to driver's physiology & psychology under different ice-snow roads conditions (as different ice-snow road alignment, etc.). Experimental studies have shown that when driving on the ice-snow pavement, ice-snow steep slope or ice-snow continuous curve, the drivers' physiological load and physical burden are increased obviously; this indicates that it is unfavorable driving under these conditions.
