摘要
为了提高干线公路穿越城镇路段的行车安全性,探究车辆在干线公路穿越城镇路段上的行驶特性,通过实地调研车辆的速度、加速度及驾驶员操作次数的变化的相关数据,以交通工程学和人因工程学为基础,对干线公路穿越城镇路段上的交通特性进行了研究。根据干线公路穿越城镇路段的道路环境特点,界定了公路段与城镇段之间的适应段;分析车辆实际运行速度与设计速度之间的一致性和相邻路段的速度协调性,确定在交叉口、中央分隔带开口、曲线路段的安全隐患较大并且从公路至城镇方向运行速度呈递减状态;分析公路段、适应段和城镇段相同长度路段上车辆的变速次数和加速度标准,为交通控制措施的制定和道路线形设计的优化提供参考。
In order to improve the driving safety of the main road crossing the urban road section,and explore the driv ing characteristics of the vehicle in the process of crossing the town through the road,we investigated the changes of the speed,acceleration and the number of driver operations.Based on traffic engineering and human factors engineering,we studied the traffic characteristics of the main road crossing the urban section.According to the characteristics of the road environment of the main road crossing the urban road section,the adaptation section between the road section and the ur ban section is defined;the consistency between the actual running speed of the vehicle and the design speed and the speed coordination of the adjacent road sections are analyzed,and the intersection is determined.The safety risk of the opening of the mouth,the central separation zone and the curved section is large and the running speed from the road to the town is decreasing.The speed and acceleration standard of the vehicle on the same length of the road section,the ad aptation section as well as the urban section are analyzed to provide reference for the development of measures and the optimization of road alignment design.
