The characteristics of the process that the combination of static and dynamic of risk driving scenarios are analyzed, and the definition of the situational risk degree （SRD） of the risk driving scenarios is given. A quantitative evaluation method of the risk degree of risk driving scenarios is put forward based on the traffic conflict analysis technology and subjective evaluation. Taking six typical risk driving scenarios as research objects, the traffic conflicts’analysis for the expert subjects’driving behaviors under the risk driving scenarios are picked up through the driving simulation experiments. Combined with the correction of the subjective evaluation results, a driver＇s perception ability of human risk identification standard is built. Through analyzing the differences of driving behaviors between different risk driving scenarios, the impact of SRD on driving behavior is verified. The experimental process, method and conclusions in this paper provide theoretical and practical reference for the driver＇s perceive hazard perception test in China.
