Abstract

This paper presented a time-varying network shortest path algorithm based on priority queue to solve the time-varying network shortest path problem which was difficult for traditional shortest path algorithm. The proposed algorithm could address optimal solution by using proposed time-window selection strategy which could select appropriate time window for the node to reduce the path length. Also, the algorithm used the priority queue to organize node set, which could improved the computational efficiency. Experiments on randomly generated network data and united state road data show that compared with classical algorithm, the proposed algorithm is not only able to obtain global optimal solutions, but also improve the speed of the algorithm.
