英文摘要：

Auction algorithm is a new and simple algorithm for finding the shortest paths inadirectedgraphproposedby Prof. Bertsekas and has been extended and applied to avariety of linear network flow problems. The auction algorithm for the shortest paths was introduced and its characteristics were analyzed. The auction algorithm is compared with other widely used algorithms such as label-setting algorithm and label-correcting algorithm. The properties of the urban street network and the peculiarities of finding the shortest paths during traffic assignment were analyzed profoundly. The study results show that the auction algorithm is suitable to the parallel implementation and solving the large-scale sparse network. These fulfill the properties of actual road network and the requirements of the traffic assignment. A lot of computation amount can be avoided and the computing time can be reduced by the use of the auction algorithm in traffic assignment. Auction algorithm can be broadly applied in transportation fields.
