高速公路改建运行速度协调性研究

Research on Speed Coordination of Expressway Reconstruction

随着城市建设发展和精细化管理,早期建设的公路线形指标虽能满足规范要求,但其安全性和舒适性相对较低。针对该问题,以上海市S4公路奉浦大桥东桥及接线改建工程为例,引入运行速度v85,通过分别对小客车和大货车运行速度协调性评价分析,明确了改建工程的线形设计方案。为今后类似工程的设计提供借鉴意义。

With the development of urban construction and the elaborating management,highway alignment of the construction of the early indicators can meet the specification requirements,but its safety and comfort is relatively low.For that matter,taking Shanghai S4 highway fengpudong bridge and the reconstruction project as an example,the running speed is introduced,and the linear design scheme of the reconstruction project is made clear through the evaluation and analysis of the coordination of the running speed of small buses and large trucks.It provides reference for the design of similar projects in the future.
