VISSIM仿真技术在道路施工期交通组织中的应用——以广深高速新塘立交段改扩建工程为例

研究基于VISSIM交通仿真软件,搭建广深高速新塘立交段现状交通运行模型,标定模型中各阶段涉及到的车辆-驾驶行为参数。在此基础上,对施工期间交通组织方案进行仿真测试,并根据测试结果对施工期间交通组织方案提出改善建议,最后通过仿真模型,验证改善措施对施工组织期间对车辆通行效率的有效性。研究通过仿真软件定量评价和直观展示广深高速公路新塘互通立交改造期间的交通运行情况,为新塘立交施工期间"保畅"提供理论支持。

Application of VISSIM Simulation Technology in Traffic Organization during Road Construction--Take the Reconstruction and Expansion Project of Xintang Interchange of Guangzhou-Shenzhen Expressway as an example

Based on the VISSIM traffic simulation software,the current traffic operation model of Xintang Interchange of Guangzhou-Shenzhen Expressway is built,and the vehicle-driving behavior parameters involved in each stage of the model are calibrated.On this basis,a simulation test was carried out on the traffic organization plan during the construction period,and suggestions for improvement of the traffic organization plan during the construction period were put forward based on the test results.Finally,the simulation model was used to verify the effectiveness of the improvement measures on the efficiency of vehicle traffic during the construction organization period.The research uses simulation software to quantitatively evaluate and visually display the traffic operation during the reconstruction period of Xintang Interchange of Guangshen Expressway,and provide theoretical support for the"smoothness"during the construction of Xintang Interchange.
