Research On The Application And Optimization Of Urban Bus Transit Network

The optimization of public transportation wire is the main part of municipal transportation plan, is one of the effective actions which can alleviate city public transportation tense aspect under the limited resources condition. The wire optimization goal and the constraint condition are studied in this article systematically, the public transportation wire optimization model and the optimized method are established, and the reasonable adjustment method is proposed in thesis for the public transportation wire.Firstly, based on the advanced theory and in the method which other national and the local public transportation network optimizes, this article unifies Huhhot the public transportation present situation, through to public transportation wire thorough careful analysis, From its constituent spot, line obtaining, the analysis influence mass transit demand forecast influence factor, established the models of the inhabitant to go on a journey, of the inhabitant goes on a journey the attraction and the inhabitant goes on a journey the distributed, this models are used to carry on the forecast to the inhabitant public transportation journey demand, in the proceed the TRANSCAN software is used. Next, the influence factor which the public transportation wire optimizes has analyzed, from the passenger service level and the public transportation enterprise's benefit angle, the multi-objective public transportation wire optimization model has established, and its objective function and the constraint condition has been carried on the discussion on. Then, in view of the present our country city public transportation wire optimization question, the city public transportation wire optimization algorithm has been discussed.Finally, in this article the Huhhot city public transportation wire optimization is taken as an example, beginning with Huhhot's geography condition as well as the public transportation present situation, Carries on the optimization using the establishment model to Huhhot's public transportation wire, and used the simulation annealing algorithm to carry on the solution to it, the the optimized adjustment methods are proposed union existing public transportation wire.
