摘　　要：在对北京市航天桥环形交叉口进行实际交通调查的基础上,建立了其路网交通仿真模型。根据实际调查的交通流量数据,设计了航天桥环形交叉口的2套信号控制方案。通过Transmodeler3.0交通仿真软件对2套信号控制方案进行仿真和仿真结果的对比分析,确定了其中的最佳方案。该方案能够使航天桥环形交叉口的交通信号控制满足实际交通需求,提高航天桥环形交叉口的交通控制效果。Based on the actual traffic investigation of Hangtian Bridge roundabout intersection in Beijing, the traffic sinmlation model of road network is established. According to the traffic flow data of actual investigation, the two signal control schemes of Hangtian Bridge roundabout intersection are designed. The two signal control schemes are simulated using Transmodeler3.0 traffic simulation software, the results are compared, and the best signal control scheme is determined. This scheme can make the traffic signal control of Hangtian Bridge roundabout intersection meet the actual traffic demand and improve the control effect of Hangtian Bridge roundabout intersection.
