Complete Route Computing for Traveling by Public Transport

It is important for cities to develop public transport system in order to solve existing traffic problems.In this paper,we propose a solution for complete route computing: first we build two models-the bi-level public transport network model and the pedestrian network model,and then connect the two networks as one unified mixed transportation network based on which we compute the complete route.In complete route computing,first route is planned on the upper part of the transport network(Level2),then transport transfer solution is calculated on the lower part of the transport network(Level1),in the end pedestrian network model is employed for walking path guidance in the transfer area.Thus we can realize the complete route computing for traveling by public transport.
