摘　　要：城市道路交叉口存在交通需求量大、通行速度慢等问题,影响交叉口通行能力。较多研究从交通渠化设计和管理措施上探讨了交叉口的优化方法,但关于交叉口的运行状态评价研究有待深入。本文在分析城市道路交叉口特点、总结交叉口优化方法与评价指标的基础上,结合大连市交叉口改造实例,提出相应的交通组织优化策略,并应用VISSIM仿真软件模拟交叉口现状与优化后的交通特性,以出行时耗作为交通运行状态改善程度的评价指标。仿真结果表明改善后的交叉口出行时耗有所减少,交叉口优化确有裨益。Urban road intersections have problems such as high traffic demand and slow traffic speed,which has affected intersection capacity.More studies have discussed the optimization methods of intersections in terms of traffic canalization design and management measures,but the study on the evaluation of the operation status of intersections needs to be deepened.In this paper,on the basis of analyzing the characteristics of urban road intersections,summarizing the intersection optimization methods and evaluation indexes,combining the example of intersection reconstruction in Dalian,the corresponding traffic organization optimization strategy is proposed,VISSIM simulation software is applied to simulate the traffic characteristics of intersections before and after the optimization,and travel time consumption is used as the evaluation index of the improvement degree of traffic operation state.The simulation results show that the travel time consumption of the improved intersection has been reduced to prove that the intersection optimization is really beneficial.
