Research On The Configuration Of Intercity Passenger Transport Mode In Urban Agglomeration

With the rapid development of my country’s economy,the process of urbanization has been accelerating,and several cities in the region have shown a trend of group development,that is,urban agglomerations have begun to form.Within the scope of urban agglomerations,the frequent flow of economic factors between cities has stimulated a large number of regional passenger and cargo transportation needs,and also put forward higher requirements on the transportation system.Under the situation of high-quality regional socio-economic development and increasing traffic demand,scientific and reasonable guidance on the configuration of inter-city passenger transportation modes in urban agglomerations is very important for the efficient use of resources and the sustainable development of transportation systems effect.Based on the general project of National Natural Science Foundation of China(52072044),this paper systematically summarizes the research status at home and abroad,this paper first elaborates the basic characteristics and types of urban agglomerations,and then analyzes the characteristics of intercity traffic demand from the macro and micro perspectives.Then,through the study of the characteristic traffic mode types of the main inter-city passenger transport modes,it provides a theoretical basis for the configuration of inter-city passenger transport modes.Secondly,the ideas and methods for forecasting the demand for intercity passenger transport in urban agglomerations are put forward.Through the analysis and review of various current traffic demand forecasting models,the principal component analysis method is used to extract the comprehensive influencing factors of passenger demand and introduce them into the gravity distribution forecasting model,and combine multiple Logit models to influence the distribution of intercity traffic and the sharing rate of traffic modes.Make predictions.Then,through the game analysis of the stakeholders of the intercity passenger transportation mode,the idea of configuring the intercity passenger transportation mode of the urban agglomeration is put forward.When selecting the target,taking into account the demands of all stakeholders,the minimum travel cost of passengers,the minimum cost of transportation companies,and the minimum energy and environmental cost that the government pays attention to are selected as the targets;when determining the constraints,the balance of supply and demand,construction investment,and environment Constraints such as pollution and travel time;in the model solving stage,a genetic algorithm is designed to solve the constructed multiobjective configuration model.Finally,take the Guanzhong Plain urban agglomeration as an example to predict the traffic distribution between cities in the core area in the future;apply the constructed multi-objective planning model to solve the reasonable traffic pattern between Xi’an and Tongchuan in the future,then propose configuration suggestions based on detailed analysis of configuration results.
