宜昌市夷桥路立交方案研究

Study of Yiqiao Road Interchange Scheme in Yichang City

城市立交具有用地紧张、交通流复杂、限制因素多的特点,依托宜昌市夷桥路立交市政工程,从建设条件、功能定位到立交方案的选择、优化,系统地阐述城市枢纽型立交的方案研究过程,并对最终优化后的推荐方案,运用交通仿真手段进行模拟。结果表明:该立交方案的交通适应性良好。

The urban interchanges have the characteristics of limited land, complex traffic flow and many limiting factors. Based on Yichang Yiqiao Road Interchange Project, the article systematically sets forth the scheme study of urban hub interchange from the selection and optimization of construction condition,functional orientation and interchange scheme, and simulates the optimized recommended scheme by the traffic simulation method. The result shows that the traffic applicability of this interchange scheme is excellent.
