基于潮汐交通的可变车道分流带设置研究

为了提高潮汐交通道路的安全度,基于南京市虎踞路调查的交通数据,分析其潮汐交通特性,针对潮汐路段提出优化设计方案,在可变车道内,分析车辆的速度、道路宽度以及汽车转弯半径对分流带长度的影响,利用切函数与约束函数,设计一定长度的自动可移动式分流带。利用交通微观仿真平台vissim对实施协调控制后的结果进行仿真实验,结果表明控制后的车头间距增大,通行效率得到提高,安全度提高。

Research on tidal traffic based variable lane isolation belt setting

In order to improve the road safety of tidal traffic,with the traffic survey data of Huju Road in Nanjing,the paper analyzes its tidal traffic characteristics.To optimize the design of the tidal sections within the variable lane,the paper analyzes the effect of the road width,vehicle speed and turning radius,and uses tangent function and constraint function to design the length of a automated movable split belt.After the implementation of coordinated control,with the use of microscopic traffic simulation platform vissim,the simulation experiment result shows that the vehicle spacing traffic efficiency and safety can be improved.
