| 摘 要： | 为探索紧急情况下驾驶人跟车危险认知机理,利用图像式汽车行驶记录仪在中国首次开展了大规模的交通冲突调查,基于采集的实际交通环境下的追尾冲突数据,分析了驾驶人制动操作与驾驶人安全和危险状态判断之间的关系,提出了基于Logistic回归的驾驶人跟车危险认知模型。研究结果表明:车头时距和碰撞时间是影响驾驶人跟车危险判断的重要参数;经模型的拟合优度和预测准确性检验,提出的模型在城市交通环境下具有较好的适用性。

| Abstract: | In order to explore the mechanism of driver risk perception in car-following under emergency situations,a large-scale investigation of traffic conflict was conducted by using video drive recorder for the first time in China.Based on the rear-end conflict data recorded in real traffic environments,authors analyzed the relationship between driver braking operation and decision-making for safe and dangerous status,presented the model of driver risk perception in car-following based on Logistic regression.Resul... |
