为研究长三角交通更高质量一体化发展的路径，从设施网络、枢纽效能、运输服务、科技创新、交产融合、治理能力6个方面，分析了长三角交通运输一体化取得的成效；对标打造世界级城市群的发展定位，发现长三角交通运输实现更高质量一体化还面临方式与地区间发展不平衡、设施互联互通不足、枢纽国际竞争力不够、协作治理体系不完善等突出问题；提出了长三角交通运输一体化的总体思路，即紧扣“一条主线”、着力“建设三区”、实现“六大定位”；围绕目标定位，提出了线网深度互联、枢纽能级提升、运输无缝衔接、创新智慧引领、协调联动机制等交通更高质量一体化的实现路径。

This paper reviews the ideas and the paths of higher quality integrated development of transportation in the Yangtze River Delta, to provide some food for thought with respect to the construction of transportation power pilot sites, in the following six aspects: the facility network, the hub efficiency, the transportation service, the scientific and technological innovation, the transportation and production integration, and the governance capacity, as well as the achievements of transportation integration. For the development orientation of building world-class urban agglomerations, the integration of transportation with higher quality is faced with various outstanding problems, such as the unbalanced development between modes and regions, the insufficient interconnection of facilities, the insufficient international competitiveness of hubs, and the imperfect cooperative governance system. In view of the new trend and requirements of future development, the paper highlights the general idea of the transportation integration. It is suggested to focus on the target positioning, the realization path of the transportation integration with higher quality, with a deep interconnection of the line network, the improvement of the hub energy level, the seamless connection of transportation, the innovative wisdom guidance, and the coordination linkage mechanism.
