潮汐车道交通流特性与设置方案仿真研究

为缓解当前城市道路资源紧张、交通拥堵日益加剧的问题,在阐述国内外潮汐车道应用现状基础上,针对北京市潮汐交通现象明显的立汤路和朝阳路,进行了高峰时段交通调查,分析了潮汐车道交通流特性,论证了设置潮汐车道的可行性。根据路段现状设施、交通流量和流向特征,提出了潮汐车道设置方案,并采用Vissim仿真方法,对潮汐车道设置效果进行了评价。结果表明,潮汐车道对提高路段主要交通流向通行能力和降低延误有着重要作用,而且对次要交通流向通行能力影响不大。

Traffic Flow Characteristics on Reversible Lane and Its Operational Plan Based on Simulation

To increase the capacity of urban roads and alleviate traffic congestion problems,this paper studies reversible lane application in reference to the existing literature.Peak hour traffic surveys are carried out for Litang Road and Chaoyang Road in Beijing,which have the significant tidal traffic phenomena.It analyzes traffic flow characteristics and feasibility of using reversible lane for the two roads,and presents the operational plan based on road condition and traffic flow direction.Finally,this paper evaluates the effect of reversible lane by using Vissim simulation method.The results show the reversible lane operation can improve capacity and reduce delays on the mainline traffic flow,but has little effect on the secondary traffic flow.
