摘要
分析了道路施工引起的车道关闭特性,研究了施工关闭车道区域内车辆的驾驶特性,包括上缓冲区、作业区和下缓冲区的驾驶行为变化;同时研究了道路施工对交通通行能力的影响,分析了车道关闭型式、货车比例、施工作业区长度和限速值等因素,并给出了对应的通行能力折减系数,为道路施工车道关闭作业提供了理论参考。
The impact of road construction on lane closure is analyzed. The driving behaviors among the construction zones of lane closure are studied including the traffic transformation in the upper buffer zone,work zone and bottom buffer zone. Finally, the influence of road construction on traffic capacity is studied.The factors of lane closure type, truck proportion, work zone length and speed limit are analyzed. The corresponding traffic capacity reduction coefficient values are given, which can provide the theoretical references for the lane closure of road construction.
