Evaluation of Comprehensive Traffic Development Level of Urban Agglomeration in China

Research purposes: Urban agglomerations are the core carrier of Chinas economic development. Focusing on economic development advantageous areas such as central cities and urban agglomerations, thus driving the overall improvement of national economic benefits is a breakthrough direction for China s regional economic development. This paper aims to reasonably assess the development level of the city's comprehensive transportation system, clarify the development degree and gap of the current system, and guide the future direction of comprehensive transportation system development.Research conclusions: ( 1 ) The comprehensive transportation development level of the eight representative city agglomerations is: Yangtze River Delta Region, Guangdong - Hong Kong - Macao Greater Bay Area, Chengdu -Chongqing Twin Cities Economic Circle, Beijing - Tianjin - Hebei Region, Yangtze River Midstream City Cluster, Central Plains City Cluster, Harbin - Changchun City Cluster, Hohhot - Baotou - Erdos - Yulin City Cluster. (2) From the perspective of coordination, the Yangtze River Delta Region and the Guangdong - Hong Kong - Macao Greater Bay Area are high - quality coordinated development categories; The Beijing - Tianjin - Hebei Region, the Yangtze River Midstream City Cluster and the Chengdu - Chongqing Twin Cities Economic Circle are good coordinated development categories; The Central Plains City Cluster and the Hohhot - Baotou - Erdos - Yulin City Cluster are intermediate coordinated development categories; The Harbin - Changchun City Cluster is a primary coordinated development category. (3 ) The comprehensive transportation development of China's national urban agglomerations is relatively coordinated, and there is a certain imbalance in the transportation development of regional urban agglomerations, and the development of transportation systems in regional urban agglomerations should be paid attention to in the future. © 2023 Editorial Department of Journal of Railway Engineering Society.
