The invention relates to the technical field of road congestion cost calculation, in particular to a dynamic traffic bottleneck prediction method based on causal anonymous migration, comprising the following steps: S1, calculating congestion level cost of each road in a road network; s2, calculating the congestion propagation cost of each road in the road network based on a causal anonymous walk principle; s3, adding the congestion level cost and the congestion propagation cost of the road to obtain the total congestion cost of the road; if the total congestion cost of the road is greater than a set bottleneck threshold value, the road is a traffic bottleneck, otherwise, the road is a normal road; according to the invention, the traffic bottlenecks at different times in the road network can be accurately predicted, so that the traffic can be timely controlled, and the traffic jam condition can be relieved.
本发明涉及道路拥堵成本计算技术领域,具体是基于因果匿名游走的动态交通瓶颈预测方法,包括以下步骤:S1、计算路网中各个道路的拥堵水平成本;S2、基于因果匿名游走原理计算路网中各个道路的拥堵传播成本;S3、将道路的拥堵水平成本和拥堵传播成本相加,以得到该道路的总拥堵成本;若该道路的总拥堵成本大于设定的瓶颈阈值,则该道路为交通瓶颈,反之为正常道路;本发明能够精确预测出路网中不同时间的交通瓶颈,进而及时的控制交通,以缓解交通拥堵情况。
