Research On Person Trip Characteristics And The Capacity Structure Model Of Passenger Transport For Rural Population

In recent years, with the acceleration of the process for "new countryside construction", project "extend road coverage to every village" has improved steadily, the trip environment and conditions of rural population has been significantly improved. However, due to natural conditions and social economic constraints, as well as the backward transport infrastructure, There are many problems of travel environment for rural population, such as low road network density, poor road alignment, less line extension, the allocation of transport capacity structure is irrational, lack the necessary passenger stations, fields and points. Such a situation relate to do not understand the trip characteristics of rural population and lack of scientific planning for rural passenger transport, the configuration of related hardware and software are incompatible, and can not fulfill the needs of the rural population trip in maximum extent, is also difficult to meet the future development.In this dissertation, on the basis of field research in typical region of the country, obtain the general rule through statistical analysis trip characteristics of rural population; carry out disaggregate model to further study the trip rule of rural population; and combine characteristics of rural passenger transport, take safety and economy as the base to construct multi-objective non-linear and constrained transport capacity structure model. The study and important conclusion is mainly reflected as follows:(1)On the basis of a large number of field research and statistical analysis, obtain the general rule of trip characteristics for rural population, and through comparative analysis natural environment, economic conditions and rural character in each areas, get the specific factors which influences trip intensity, trip distance, trip mode and trip time distribution;(2)Used disaggregate theory to build the rural population trip-related model, then analyze the influence of individuals, families and trip attributes to trip characteristics,get specific parameters of various factors in the relevant model; Use economic elasticity theory to analyze the specific influence of various factors to trip rule; Based on probability theory and advanced mathematics-related knowledge, export rural trip distance formula and get the regression formula for calculating model parameters, then build trip distance model. Thereby get rural population's trip characteristics which reflect the specific rule and influence factors of rural population trip comprehensively and systematically from "appearance" to "internal"(3)Based on rural population's trip characteristics and passenger transport status, analyze the rural road transport safety factors from four aspects of human,vehicle,road and environment. Analysis the economic factors in rural passenger transport in the macro and micro level conduct by the "demand" theory, construction the rural passenger safety evaluation model and propose the suitable related formula for calculating the economy of rural passenger transport;(4) In terms of passenger safety and economy as the objective function, some related factors as the constraint conditions, established the distribution model of the capacity structure of rural passenger transport, the principal features of the model are multi-objective, multi-constraint and non-linear; then construct an algorithm for solving the model by penalty functional method.This dissertation conduct a case study with a certain area for example to qualify the model, and point out that in actual capacity structure allocation, the research results should be applied with the combination of some special measures according to the trip characteristics of rural population and the status of passenger transport.
