The invention discloses a novel mixed traffic flow-oriented urban road network bottleneck road section identification method, which is characterized in that the bottleneck road section is a fixed bottleneck and is a common bottleneck; the method comprises the following steps: acquiring road network information of an experimental road network; the road network information comprises a topological structure; establishing a novel mixed traffic flow network balancing model according to the road network information; congested road sections of the experimental road network are screened according to the road section saturation; determining the congestion criticality of a congested road section in the experimental road network based on a network equalization model; determining the connectivity of the congested road sections according to the topological structure of the road network; determining the road section OD weighted betweenness of the congested road section according to the network equalization model of the road network; based on the congestion criticality, the connectivity and the road section OD weighted betweenness of the congested road section, determining the comprehensive importance of the congested road section by adopting an entropy weight method; and determining a bottleneck road section according to the comprehensive importance degree of each congested road section. According to the method, accurate identification of the bottleneck road section is realized.
