| 摘 要： | 为研究雾霾天气下车辆跟驰行为,基于8自由度高逼真驾驶模拟器,设置晴天和雾霾天两个实验场景,采集不同交通状态下跟驰驾驶行为数据,分析车头时距、车头间距、车头延迟时距、加速度、减速度等跟驰行为关键变量.实验结果表明,雾霾天气显著影响了跟驰行为,最大车头间距在自由流、拥挤流和阻塞流跟驰状态下分别增加了8.7%、19.4%和25.6%;自由流跟驰状态下最小车头间距减小了13.0%;阻塞流跟驰状态下最小车头时距减小了47.9%,但延迟时距及其离散性增加了15.5%和28.2%;雾霾天气下后车的加速行为更为谨慎.不同交通状态下的跟驰行为存在显著差异.随着跟驰车速增加,最大、最小车头间距及其离散性显著增加;最大、最小车头时距及其离散性则呈先增加后减小趋势,延迟时距显著增加.
