港区道路出入口交通组织形式和分离距离

Access Management and Separation Distance on Port Roads

摘要:

针对大型车为主的道路交通状况,对港区货车和集装箱卡车等大型车的交通特性进行了调查研究，并在此基础上对港区常见的出入口交通组织形式进行了理论分析和仿真评价.研究表明，当主路单车道流量大于400 veh·h-1或支路左转车流大于250 veh·h-1时，冲突车流间干扰大大增加，此时建议采用C型信号控制形式的出入口. 提出了出入口分离距离的理论计算公式，并对分离距离的安全和效率进行了仿真验证.

Abstract:

A research was made of the heavy vehicle traffic in port area to investigate its traffic characteristics. Based on the theoretical analysis and simulation, the type of traffic organization, Type C, was recommended for the access when the traffic volume of main roads is over 400 veh·h-1 or the left turn volume of minor road more than 250 veh·h-1. In addition, a theoretical calculation method of separation distance was also proposed, which was verified by a VISSIM simulation model for its safety and efficiency.
