Regulation and Control Strategy of Highway Transportation Volume in Urban Agglomerations Based on Complex Network

Urban development within an urban agglomeration is unbalanced; the coordinated development of urban agglomerations is the core task of urban development. There are now many mechanisms and methods to promote the coordinated development of urban agglomerations; however, there is a lack of research on promoting the coordinated development of urban agglomerations from the perspective of highway transportation volume regulation. According to the physical characteristics of highway transportation networks, the logical characteristics of urban regional connectivity, and the connection characteristics of complex networks, a two-layer complex network model was designed. The objective function and constraint conditions for urban agglomeration transportation volume regulation were proposed, and the optimal solution of the highway transportation volume regulation was solved. Due to the many variables and constraints, a hierarchical solution method was adopted. A probability search iteration algorithm was proposed innovatively to solve multivariable, many-to-many allocation problems. The algorithm is universal and can be applied to solving similar problems. Taking provincial urban agglomerations as an example, the process of solving the regulation model and realizing the method was explained. The transportation volume regulation methods and strategies proposed in this study realize the best combination of macro control and micro control, static and dynamic control, coordinated development, and collaborative transportation. It is an innovative exploration and study of highway transportation volume allocation and collaborative transportation in urban agglomerations and opens up a new direction for research on the coordinated development of urban agglomerations. The coordinated development of urban agglomerations provides a guarantee for the sustainable development of urban agglomerations. Therefore, this study is also of great significance for promoting the sustainable development of urban agglomerations.
