Theory Of Comprehensive Passenger Transportation Corridor Supplying Structure Planning

The rapid growth of regional transport demand needs to add a large number of infrastructures, application of new technology to change the features of transport modes'passenger products, competition of comprehensive transportation corridor passenger market is performing in wider range and deeper expansion, corridor's passenger transport demand structure will presents the new equilibrium in time and space two aspects. In depth analysis of the influence factors and regularity of long distance passenger travel behavior and the relationship of transport operators and traveler, dynamic study of the comprehensive transportation corridor passenger system internal mechanism and external performance, forming the methodology which can analyse the equilibrium of comprehensive transportation corridor passenger transport demand structure and interaction regularity of passenger transport supply and demand structure, is conducive to strengthening the scientific of infrastructure construction, rationality of passenger transport products and the coordination of modes.On the basis of comparison of urban traffic demand and regional traffic demand, urban traffic network and the regional transportation network, proof the particularity of regional transportation planning and the necessity of developing the regional transportation planning theory. And this article in-depth analysis of current situation of comprehensive transportation corridor passenger supply and demand structure, defined related concepts about comprehensive transportation corridor passenger demand structure. On this foundation, put forward the principles, objectives and key tasks of comprehensive transportation corridor passenger transport supply structure planning, enriched and improved the comprehensive transport planning theory.For passengers in comprehensive transportation corridor have the characters of long travel distances and low frequency, the sampling methods based on alternatives was used in Revealed Preference and Stated Preference surveys. Analyzed influence factors of medium and long distance travel passengers'mode choice. According to the theory of disaggregate built a comprehensive transportation corridor passenger choice behavior model and complete the parameter calibration. The model analysis of the spatial and temporal distribution of passengers'demand in comprehensive transportation corridors, simulated the change of passenger choice behavior with departure time and travel distance, gets the passengers'demand structure under the condition of long and short-distance in all time periods, and analyzed the advantages of various typical passenger products.The article studied the forecasting method of market equilibrium in regional passenger transport corridor under the conditions of competition. According to the demand characteristics of regional transport network, built a bi-level game model to simulate the internal operating mechanism of regional passenger transport corridor. Upper level is a complete information dynamic game between transport modes; lower level is a generalized Nash game for all types of traveler. The model demonstrated the impact of variables such as fare, service frequency and vehicle capacity to operation cost, benefit and traveler's utility, reflecting affect of the traveler's choice to the adjustment of transport modes. The algorithm solved the upper level game based on optimization theory and found the equilibrium of the lower level game by solving an equivalent variation inequality employing the diagonalization algorithm, then obtained the approximate equilibrium of the model by iteration.Case sdudy planned the supplying structure of passenger products and infrastructures in Beijing-Shanghai transport corridor. Calculated the equilibrium of medium and long distance and short distance passenger market, and simulated the impact of high-speed railway on passenger market in corridor. Case study of Beijing-Shanghai transport corridor shown the operation of high-speed rail can reduce the travel cost between Beijing and Shanghai, especially for the high-income travelers; the model can simulate the dynamic process of interaction between transport modes and travelers and provide the recommendations for regional transport planning and transportation products designing.
