基于模拟实验的驾驶人因素对警觉特性的影响

摘要

Objective In order to analyze the driver's factors affecting driving vigilance,an simulation experiment based on driving simulation system for testing drivers ' vigilance level was designed on the city roads. Methods Based on the drivers' braking response time as parameters, the drivers' vigilance level was analyzed and evaluated. Results It is shown that drivers' vigilance level differs on the basis of drivers' genders,but drivers' age,driving expe-rience and mileage have little effect on driver vigilance. Conclusion This experiment is valid and can be used in a-nalysis of road traffic accidents.%目的 为分析对驾驶人警觉特性影响显著的驾驶人因素,利用驾驶模拟系统,以驾驶人为研究主体,选择驾驶人特征为影响因素,选取城市道路为测试场景,设计了驾驶模拟测试实验.方法 通过采集驾驶人在测试场景下面对风险情况时的制动反应时间数据分析驾驶人特征对警觉特性的影响.结果 所设计的仿真实验与测试结果良好,不同性别驾驶人警觉水平存在一定差异;驾驶人年龄、驾龄与里程等特征对驾驶人警觉特性影响不明显.结论 研究结果可用于道路交通事故的原因分析.
