Abstract:

The development of high-speed rail led to the economic development of the city, it also has given urban residents an alternative to travel. However, due to the emphasis on time efficiency in the construction planning process of high-speed railway, the route plan is modeled on lines directly connecting large cities and the stations in non-central cities are often far away from the original urban areas. It also keeps prefecture-level rail stations outside central cities away from urban areas, where traveling residents spend a lot of time traveling, Therefore, the site selection of high-speed railway stations greatly affects the passenger flow structure of the city. By introducing the DID technology and threshold estimation method, this paper found that the location of high-speed railway stations has a threshold effect on the travel structure of urban residents. Cities with high-speed rail stations closer to urban areas will see more people go out in this way after the opening of high-speed rail. Cities farther away from high-speed rail stations have limited appeal for passengers. In addition, the study also pointed out that the threshold value of large cities with high-speed transportation facilities such as the metro to connect high-speed rail stations is much higher than that of ordinary prefecture-level cities. Over time, the radiation effects of high-speed trains on cities farther and farther away from stations, but its influence on the structure of urban passenger flow travel mode gradually tends to be stable. The conclusion of this paper has a certain reference value for the planning and construction of urban high-speed railway stations in the future.
