The invention discloses an urban road section passage key bottleneck identification method based on congestion propagation, which comprises the following steps of: fusing taxi GPS (Global Positioning System) trajectory data and online taxi-hailing GPS trajectory data, and finding a congestion propagation link by extracting a congestion event and a congestion activation event; a congestion cost function is defined, the influence caused by road section congestion is quantitatively evaluated, and a key congestion bottleneck is found according to the influence degree. The whole method is clear in process steps and convenient to operate, and has good application value.

    本发明公开了一种基于拥堵传播的城市路段通行关键瓶颈识别方法,融合出租车GPS轨迹数据和网约车GPS轨迹数据,通过提取拥堵事件和拥堵激活事件,找到拥堵传播链路;通过定义一个拥堵代价函数,量化评价路段拥堵造成的影响,依据影响程度找到关键拥堵瓶颈。整个方法流程步骤明晰,操作方便,具有良好的应用价值。
