Evaluating the strategies to solve the problem of heavy traffic by dynamic user optimal assignment method

Many ways could be used to reduce traffic flow of rush hour, such as traffic control by traffic lights and obstacle structural road, city planning by rational layout different establishments and harmonious work schedule of different occupations. On the basis of cell-based variational inequality formulation of dynamic user optimal assignment method, the advantages of reducing traffic flow of rush hour were assessed quantitatively on conditions of the different shapes of roads and the different states of lagged traffic flow. The results achieved by the proposed method is valuable in selecting the strategy in solving the problem of heavy traffic.
