Optimal Route Retrieval Model Based on Assignment Strategy

When travelers search for the traveling route, they usually take into account the number of transfers, transfer mode, trip distance, travelling time and cost and so on, so the elements such as multi-criteria and a various of traveling model and long distance can be considered in the inquery model. Therefore, the paper proposes a new searching model based on the directed network, the model not only has a good ability to satisfy the demands of multi-criteria for travellers through assignment strategy, but also can describe the transfer between the various means of transportation by setting vehicle speed. In the end, it verify the effectiveness and practicality of the model.
