摘  要：信号交叉口是新时代城市交通中的重要节点，交叉口的交通组织能力成为道路交通网络能力当中的重要指标，设计的科学合理可以降低事故发生，保障道路网络通行能力，从而保证整个城市交通网络的顺畅。如果设计不合理、不恰当则可能成为影响城市交通网络的瓶颈。基于BIM和VISSIM的信号交叉口交通组织优化利用了现代仿真模拟软件针对网络获取的交通大数据进行模拟与仿真测试评估，最终确定高性能信号交叉口交通组织方案，对于解决城市信号交叉口改善城市交通有着重要作用。该文针对这一方案提出了相关技术路线：利用BIM对信号交叉口及其关联路段进行三维建模、将BIM软件所做的三维路网图导入VISSIM软件中作为底图、运用VISSIM软件仿真进行信号交叉口优化设计。

Absrtact：  Signalized intersection is an important node of urban traffic in the new era. The traffic organization capacity of intersection has become an important index of road traffic network capacity. Scientific and reasonable design can reduce accidents， ensure the traffic capacity of road network， and ensure the smooth traffic network of the whole city. If the design is unreasonable and inappropriate， it may become a bottleneck affecting the urban traffic network. The traffic organization optimization of signalized intersection based on BIM and VISSIM uses the modern simulation software to simulate and evaluate the traffic big data obtained from the network， and finally determines the traffic organization scheme of high-performance signalized intersection， which plays an important role in solving the problem of urban signalized intersection and improving urban traffic. Aiming at this scheme， this paper puts forward the relevant technical route： Using BIM to carry out three-dimensional modeling of signalized intersection and its associated sections， importing the three-dimensional road network map made by BIM software into VISSIM software as the base map， and using VISSIM software to simulate the optimization design of signalized intersection.
