The invention discloses a
traffic network bottleneck identification method based on flow cascading in the technical field of traffic
information control, and the method comprises the steps: obtaining road data and commuting behavior data in a target area, extracting the midpoint of each road in the road data, connecting the origin-destination space of the commuting behavior data to the midpoint of the nearest road, and obtaining the
traffic network bottleneck identification result. And recording a corresponding index relationship between the origin-destination point and the midpoint of the road. The incremental traffic distribution
algorithm is adopted to distribute the travel matrix of the spatial position information, the congestion effect generated by network flow
cascade is simulated by iteratively updating the network edge weight, the network
bottleneck under the network flow reconstruction is identified, the
cascade conduction mechanism of the
traffic network flow under the disturbance condition can be systematically described, and the
traffic flow reconstruction efficiency is improved. Network bottlenecks having key influences on
system stability are identified, and the response capability and structural
toughness of urban risks are improved.
