The Impact of Tianjin-Baoding Intercity Railway on the Traffic Pattern of the Jing-Jin-Ji Urban Agglomeration

摘要

The construction of transportation infrastructure has a profound influence on regional and urban development. The high-speed rail can greatly enhance the transport and economic connection of the urban agglomerations separated. This research aims to examine the impact of the Tianjin-Baoding Intercity Railway (TBIR) on the transportation pattern in the Jing-Jin-Ji urban agglomerations. With the help of ArcGIS Desktop10, the traditional accessibility assessment model was conducted to analyze the changes of accessibility before and after the construction of TBIR. The model was modified to illustrate the non-transportation-network grids in details. The grids were evaluated by geographical factors (water surface, elevation or slope) or land use types instead of being regarded as homogeneous in traditional model. The result shows that the time accessibility of Tianjin and Baoding is greatly improved with the TBIR, while the other cities in the urban agglomerations are not as significantly improved as the former two. The research believes that the TBIR exerts a significant influence on the transportation pattern of the Jing-Jin-Ji urban agglomerations, compresses the time and space between Tianjin and Baoding, and it significantly improves the importance of Baoding, which may change the urban agglomerations from "sin-Hub" to "bi-Hubs". Finally, this paper analyzes the impact of the TBIR on the industry of commerce and trade, tourism, real estate, regional logistics network and so on.
