上海市中心城区快速路潮汐车道设置方案研究——以南北高架为例

Research on Layout Scheme of Tidal Lanes on Expressways in Central Urban Area of Shanghai for North-South Elevated Road

摘要:

城市快速路作为城市组团之间空间联系的骨架，是中心城区路网结构的重要组成部分。目前上海市快速路网容量基本饱和，早晚高峰时段交通拥堵频繁出现。充分调研国内外关于潮汐车道的研究成果和应用案例，结合上海市中心城区快速路交通运行的时空特征，对上海市快速路网潮汐车道进行适应性分析，提出设置潮汐车道应具备的交通需求及交通设施条件。以南北高架为例，详细论证潮汐车道实施方案，分析潮汐车道管理对交通运行效率的提升效果，采用VISSIM仿真进行验证。最后，从工程实施角度提出城市高、快速路潮汐车道的实施条件、配套措施及实施风险规避等相关建议，为其他类似工程提供参考。

Abstract:

As the backbone of spatial connections between urban clusters, urban expressways are an important component of the road network structure in the central urban area. Currently, the capacity of the expressways network is basically saturated, and traffic congestion occurs frequently during morning and evening peak hours in Shanghai. By thoroughly investigating the domestic and foreign research achievements and application cases of tidal lanes, and combined with the spatiotemporal characteristics of the traffic operation of expressways in the central urban area of Shanghai, the adaptability of tidal lanes of expressway network in Shanghai is analyzed, conducted, and then the necessary traffic demands and traffic facility conditions are proposed. Taking the North-South Elevated Road as an example, the applicable scheme of the tidal lane is elaborated. The effect of tidal lane management on traffic efficiency is analyzed. And VISSIM simulation is used for verification. Finally, the suggestions of implementation conditions, supporting measures and risk avoidance of tidal lanes on urban expressways are proposed from the perspective of engineering implementation, which provides the reference for other similar projects.
