Abstract
A method of evaluating traffic network reliability is provided. The method is adapted to a traffic route network with a start point, an end point and a plurality of sub-routes, and includes following steps: obtaining a connecting configuration, a plurality of threshold distribution values and a state distribution value of each sub-route; enumerating at least one path according to a maximal threshold value of the traffic route network, the connection configuration and the threshold distribution values of each sub-route wherein each path is composed of a plurality of the sub-routes and includes threshold distribution values corresponding to each sub-route, wherein if a specific path is not composed of a specific sub-route, a threshold distribution value of the specific path corresponding to the specific sub-route is 0; and, calculating a difference between a user-side network reliability and a system-side network reliability of the traffic route network based on the threshold distribution values corresponding to each sub-route of each path and the state distribution value of each sub-route.
