本文研究了驾驶员在真实交通危险工况中的制动反应时间。通过对上海地区采集到的真实交通工况进行筛选和分类，得到6种典型的危险工况类型。对这6种危险工况，特别是“前车减速”工况中驾驶员制动反应时间进行了测量和分析。结果表明，驾驶员的制动反应时间随危险工况类型不同而不同。相对于由其他车辆导致的危险，当危险是由行人等易受伤害的道路使用者引起时，驾驶员的制动反应时间更短。在“前车减速”工况中，当车速上升、危险紧急程度增加或者在非路口行驶时，驾驶员制动反应时间有减小的趋势。本研究为开发适合我国特殊交通状况的先进驾驶辅助系统提供依据。

The brake reaction time of drivers under real traffic risk scenarios is studied in this paper. Real traffic scenarios collected in Shanghai are screened and classified, and six typical types of risk scenarios are ob-tained. Driver brake reaction times under these six types of risk scenarios, especially the scenario of“front vehicle decelerating”, are measured and analyzed. The results show that driver brake reaction time is obviously different for different type of risk scenarios. Compared with the risk caused by vehicles, the driver brake reaction time for the risks caused by vulnerable road users is shorter. In the scenario of “front vehicle decelerating”, when the vehicle speed goes up, the risk urgency increases or the scene is not on the road intersection, the driver brake reaction time tends to reduce.
