The Sustainable and Coordinative Development of Road Transportation Infrastructure and Economy

In view of the problems faced by sustainable urban development and coordinative development of road transportation infrastructure and economy, the paper introduced the importance of the coordinative development of road transportation infrastructure and economy. The coordinative development of urban subsystems is the basis for sustainable urban development. The urban subsystems' coordinative development is not only an important component of sustainable urban development, but also promotes to build a resource-saving and environment-friendly society. According to synergetic principles, this paper analyzes the coordinative development of road transportation infrastructure and economy theoretically, and then establishes the coordinative degree model between them. At the same time, the method of gray relational grade analysis is used to determine the weight of the evaluation function objectively.
