Urban traffic reliability index based on seepage analysis, and implementation method for urban traffic reliability index

The invention discloses an urban traffic reliability index based on seepage analysis, and an implementation method for the urban traffic reliability index, and the method comprises the following steps: 1, carrying out the preprocessing of urban traffic data information; 2, building a traffic dynamic network based on the urban traffic data information, taking the traffic flow data of each segment in an actual urban traffic system as the basis, and carrying out the empowerment operation of a network; 3, analyzing the seepage attributes of the traffic dynamic network, finding the seepage threshold value of an urban traffic network, and obtaining the urban traffic reliability index based on the above; 4, determining a bottleneck road affecting the reliability of an urban traffic system. The method dynamically gives consideration to the operation efficiency of macroscopic traffic from the network layer of urban traffic, can solve an actual problem of the accurate and complete measurement of the congestion of a traffic network system, achieves the quantification and evaluation of the reliability of the urban traffic network system, and provides a powerful method support for the smooth project and the construction of a smart city.
