城市高快速路转换交织区设计优化研究

Study on Design Optimization of Urban High-speed Road Interleaving Area

针对城市快速路和高速公路转换交织区的复杂性,以某高速公路与城市快速路市政连接线工程SE匝道为例,结合交织区的交通流向、交通出行需求等特点,从物理空间分离的角度,研究了城市复杂路段与快速路衔接交织区域的优化方案,并基于HCM2010提供的模型,计算和评价了优化前后交织区的车流密度、服务水平及工程措施,为其他高快速路转换衔接交织段的交通组织和工程改善提供了一种设计思路。

In view of the complexity of urban expressway and highway conversion interweaving zone, taking the SE route of a highway and urban expressway municipal connection line project as an example, combining the traffic flow direction and traffic demand of the interweaving zone, it separates from the physical space. From the perspective of the study, the optimization scheme of the intertwined area of the complex road segment and the expressway in the city is studied. Based on the model provided by HCM2010, the traffic density, service level and engineering measures in the interweaving area before and after optimization are calculated and evaluated, and the other high-speed road conversion is connected. The transportation organization and engineering improvement of the interwoven section provides a design idea.
