摘　　要：论述了驾驶员周边风险感知能力对行车安全的重要性,提出了周边风险感知能力检测并确立其测评指标。运用周边风险感知检测仪测试了1 325名驾驶员,并调查统计了受测驾驶员近3 a的事故记录,样本数据的统计分析证实了事故倾向驾驶员的客观存在,验证了周边风险感知检测仪的有效性和测评指标的合理性,并进一步确定了周边风险感知测评指标的阈值。结果表明:驾驶员周边风险感知能力对行车安全有显著的影响,周边风险感知能力检测可以筛选出事故倾向驾驶员。First, the importance of driver＇s peripheral risk perception ability to traffic safety is discussed, the detection of peripheral risk perception ability is put forward and its evaluation indexes are established. Then, 1 325 drivers are tested using peripheral risk perception detector, and the tested accident records of drivers in past three years are investigated. Through the analysis of the test data, the objective existence of the accident prone drivers is verified, and the effectiveness of the peripheral risk perception detector and the rationality of the evaluation indexes are proved, and the threshold of peripheral risk perception indexes is identified. The result shows that the driver＇s peripheral risk perception has a significant impact on traffic safety the detection of peripheral risk perception ability can screen out the accident prone drivers.
