With the rapid development of the social economy and the deep application and integration of new-generation information technology, integrated transportation faces serious challenges regarding safety, high efficiency, and environmental protection. To address the major demands of socioeconomic and transportation development, based on analyses of the development situation, this study conducted strategic research on the development trends and path for integrated transportation engineering science and technology to 2035. This research focused on network connections, collaboration, and intelligence. Furthermore, this paper proposes strategic plans, key directions, development paths, and major projects for integrated transportation engineering science and technology to 2035, all of which may help to provide valuable insight into the realization of a leap forward in the development of China’s integrated transportation engineering science and technology.
