The invention provides a road network traffic bottleneck identification method and device and electronic equipment, and relates to the technical field of data processing, in particular to the technical field of intelligent traffic. According to the specific implementation scheme, the method includes: taking any one of a plurality of congested road sections as a congestion starting point road section, and determining a congestion propagation relation caused by the congestion starting point road section based on congestion relevance among the congested road sections; determining a congestion propagation state value of the congestion starting point road section based on the congestion condition value of each congestion propagation road section included in the congestion propagation relationship and the historical congestion relevance between the adjacent congestion propagation road sections; based on the congestion condition value and the congestion propagation state value of the congestion starting point road section, determining a congestion comprehensive state value of the congestion starting point road section; and determining a bottleneck road section from the congestion starting point road sections based on the congestion comprehensive state value. According to the scheme, the congestion propagation effect is taken into comprehensive consideration, the accuracy of traffic bottleneck identification is improved, and a better basis is provided for improving the operation efficiency of a traffic network.

    本公开提供了路网交通瓶颈的识别方法、装置及电子设备,涉及数据处理技术领域,尤其涉及智能交通技术领域。具体实现方案为:将多个拥堵路段中的任一拥堵路段作为拥堵起点路段,基于各拥堵路段之间的拥堵关联性确定由拥堵起点路段所引发的拥堵传播关系;基于拥堵传播关系中包含的各拥堵传播路段的拥堵情况值,以及相邻的拥堵传播路段之间的历史拥堵关联性,确定拥堵起点路段的拥堵传播状态值;基于拥堵起点路段的拥堵情况值以及拥堵传播状态值,确定拥堵起点路段的拥堵综合状态值;基于拥堵综合状态值从拥堵起点路段中确定瓶颈路段。本方案中,将拥堵传播效应纳入综合考虑,提升交通瓶颈识别的准确性,为提升交通网络运行效率提供更好基础。
