Research On The Impact Of High Speed Railway Operation On Regional Freeway Passenger Transportation

Under the background of the rapid development of China's high-speed railways,the development of high-speed railways has brought about tremendous changes in the current passenger transportation sharing rate in the transportation system and passenger transportation market in China.The development of high-speed railways has the greatest impact on the passenger flow of expressways.Due to the short development time of high-speed railways,there are currently few domestic and foreign scholars studying the impact of the development of high-speed railways on highway passenger flow.The article takes the passenger flow competition of high-speed railways and expressways as the starting point to study the status quo of changes in the passenger flow of expressways after the opening of high-speed railways.When studying the impact of high-speed railways on the passenger flow of expressways,we first analyze the development status of the two different modes of transport,determine the development trends and respective advantages and disadvantages of the two different modes of transport,and compare the high-speed railway and the expressway.In terms of passenger flow attraction.In establishing a competition model for passenger and passenger flow between expressways and high-speed railways,passengers were the object of study and social surveys were conducted on the passenger flow within the study area to study the economy,safety,speed,and comfort of travelers when they traveled.The importance of different factors such as convenience and punctuality.Statistical analysis of the importance of the six factors in trips,determining the degree of influence of different factors on the utility function in the model's utility function,calculating the influence factors of different factors,and establishing a passenger flow competition model between different modes of transportation.Using the passenger flow competition model established in the article for different modes of transportation,the advantage of high-speed railways and expressway transportation in different transportation distances was analyzed.The passenger flow sharing rate between Lanzhou and Tianshui in the Baolan Passenger Line was used as an example to verify the established model.Correctness.To investigate and analyze the passenger flow between the two places,determine the coefficient value of the influence of different influencing factors on the utility function,establish the utility function to calculate the utility coefficient,and calculate the passenger flow sharing rate of the two modes of transport.According to the transport data in the actual passenger transport system,Verify the correctness of the load sharing rate calculated by the competition model.The mathematical analysis method is used to analyze the competitive advantages of different modes of transport in different aspects,and points out development strategies for highway transportation.By establishing a passenger flow competition model between different modes of transport,after analyzing the introduction of new modes of transport into the passenger transport system,the impact of passenger flow sharing rates in different transport modes of the passenger transport system will be determined,and the passenger flow sharing rate and passenger flow of the new transport modes will be determined.Provide reference for the new line's train operation plan;after the new high-speed railway is built within the scope of regional transportation,determine the impact of high-speed railway on the existing expressway passenger flow,and provide development strategies for the expressway within the region;calculate through competition model calculation Integrate the passenger flow sharing rates of different transport modes of the transport system,determine the development advantages of different transport modes at different transport distances,and determine the layout of different modes of transport in the integrated transport system so that various modes of transport can be properly connected to exert their own Transportation advantages.The rational distribution of transportation networks has important implications for optimizing transportation resources and accelerating passenger transportation efficiency.
