摘　　要：为研究专业与非专业驾驶人的跟驰安全性,以真实道路交通环境下驾驶人跟驰行为的数据采集为基础,应用碰撞时间TTC及其拓展指标TET和TIT3个跟驰安全评价指标,对比分析了受测专业及非专业驾驶人TTC频率分布和单位时间内TET及TIT平均百分比,从而对专业及非专业驾驶人跟驰安全特性进行了评价。研究结果表明在跟驰过程中专业驾驶人保持较小碰撞时间的比例比非专业驾驶人高,同时专业驾驶人单位时间内TET及TIT平均百分比大于非专业驾驶人。In order to study the safety characteristics of novice and experienced drivers in the car-following situa- tions, this paper collects the car-following behavior data under real road traffic conditions. Based on three safety indicators of TTC, TET and TIT, safety characteristics of drivers car-following behaviors are analyzed by comparing the TCT fre- quency distributions, TET average percentage per unit time and TIT average percentage per unit time of experimental novice and experienced drivers. Results show that the experienced drivers probability of maintaining smaller TTC is high- er than that of the inexperienced drivers, while the TET and TIT average probability per unit time of experienced driver is higher than that of the inexperienced drivers.
