| 摘 要： | 针对公路环境对驾驶员反应时间的影响,对停车视距模型进行了分析。从运动学原理出发,将停车制动过程分为驾驶员反应阶段、制动间隙消除阶段、制动力上升阶段和全制动阶段,推导了公路环境影响下的反应距离,得出基于公路环境的停车视距模型,并与现有模型进行比较。分析结果可为公路环境的改善和交通安全的管理提供理论依据和实践指导。

| Abstract: | Effects of highway environment on drivers＇ reaction time was taken into consideration to analyse stopping sight distance model. Based on principals of kinematics, the vehicle brake process can be divided into braking-reaction time step, brake eliminating clearance time, brake force climbing time and full braking time step, and the brake reaction distance affeetted by highway environment was deduced, and the stopping sight distance model of highway environment was built considering effects of highway environment on drivers＇ reaction time. The model was used to compare with the previously reported models. The results provided theoretical guidance and practical instructions to improvement of highway environment and management of transport safety. |
