Research On Passenger Transport Structure Optimization Of Comprehensive Transportation Corridor

With the development of economy and society, the higher demand for travel efficiency and comfort, the more attention to environment and energy for China, the more important passenger transportation of corridor is in the theory about comprehensive transportation. The advantage and disadvantage of passenger transportation structure in corridor is directly related to the sufficient display of the whole corridor passenger transport capacity. For the present existing problems of passenger transportation of corridor, on the basis of comprehensive studying the relative material in-and outside the country, the author try to combine the state 863 subject, applying the methods of system science,mathematics,operations research, it does detail research about the reasonable scheme for passenger transportation structure of corridor, the passengers' choice behavior, plan evaluation and selection, and the purpose is to provide an beneficial supporting tool for the passenger transport structure planning.Firstly, this paper links with the condition of our country and the problems of the passenger transportation structure; Secondly, according to passenger traffic mode choice behavior, this paper quantitatively analyze the major influencing factors; Then a computation model of passenger traffic sharing rates is set up, which is passenger equilibrium model, a genetic algorithm based on stochastic simulation to calculate the model is put forward; Lastly, this paper utilizes the timing evaluation method for the planning and construction programs of corridor, and analyzes the eight indexes of transportation efficiency, quality and service level respectively, develops a rational system of evaluating indicators and brings it into demonstration analysis in typical sections of Shanghai-Nanjing transport corridor.
