To match the practical application requirements, assignment network and simulation network are classified account for varying flowing loading. Instantaneous dynamic user optimum model should be applied to the former and actual dynamic user optimum model the latter respectively. The two model’s feasibility is studied as well. Considering the application in ATMS, the model is mainly used to analyze the altering OD problem. Moreover, it adds the method of route adapting into the object function selection to appraise elastic trip strategy and set up real means of route inducement.展开更多

The length of the path between any two nodes given by the algorithm is not more than (3/8)n2 + O(n), that is, the diameter of REn is not more than (3/8)n2 + O(n). This improves on a (1/2)n2 + O(n) routing algorithm proposed earlier.展开更多
