基于VISSIM的城市快速路定向车道和潮汐车道设置研究

Investigation on Directional and Tidal Lane Setting of Urban Expressway Based on VISSIM

为缓解城市交通资源分配不合理、潮汐交通现象日益显著的问题,在阐述定向车道、潮汐车道应用和发展前景的基础上,针对拥堵严重的武汉三环线关山立交至庙山立交段,根据路段现状设施、交通流量和流向特征进行定向车道和潮汐车道改造,并采用VISSIM仿真方法,对定向、潮汐车道设置效果进行评价。结果表明,潮汐定向车道的设置对提高路段主要交通流向通行能力、缩短行程时间和降低延误有着重要的影响,且对减少车道的对向车流没有受到太大影响。

In order to alleviate the problems of unreasonable allocation of urban traffic resources and the increasingly tidal traffic phenomenon,based on the introduction of the application and development of directional lane and tidal lane,the directional lane and tidal lane are reconstructed according to the current facilities,traffic flow and flow direction characteristics of the road section,aiming at the heavily congested section from Guanshan interchange to Miaoshan interchange,3 rd ring expressway in Wuhan,and VISSIM simulation method is employed to evaluate the setting effect of tidal lane.The results show that the tidal lane plays an important role in improving the capacity of the main traffic flow direction,decreasing the travel time and reducing the delay,and the opposite traffic flow of the lane is not seriously affected.
