摘　　要：交叉口作为交通流交叉和分流的节点,其运行效率直接关系到整个交通路网的畅通.为解决信号交叉口的交通拥堵问题,探索交叉口内部空间资源的充分利用,对信号交叉口直行待行区的设置技术进行分析研究.阐述直行待行区的含义,从实际应用的角度出发,提出直行待行区的设置条件和适用范围,基于“停车线法”建立直行待行区设置前后的交叉口进口道通行能力模型及利用VISSIM软件建立交叉口仿真模型,选取一城市道路交叉口分别运用所建立的通行能力模型和仿真模型进行实例分析.分析结果均表明设置直行待行区后,交叉口的通行能力明显提高,同时交叉口延误也有所下降.As the node of traffic flow intersection and diversion,the operation efficiency of intersection was directly related to the smooth flow of the whole traffic network.In order to solve the traffic congestion problem at signalized intersections and explore the full utilization of the internal space resources of intersections,the setting technology of straight-going waiting areas at signalized intersections was analyzed and studied.First of all,the meaning of straight-going waiting area was expounded,and from the perspective of practical application,the setting conditions and application scope of straight-going waiting area were proposed.Based on the“parking line method”,the traffic capacity model of the intersection entrance before and after the setting of the straight-going waiting area was established,and the intersection simulation model was established by using VISSIM software.Finally,an urban road intersection was selected and analyzed by using the established capacity model and simulation model respectively.The analysis results showed that the traffic capacity of the intersection was obviously improved and the intersection delay was also reduced after setting up the straight-going waiting area.
