Abstract
With the continuous expansion of urban scale, blindly increasing or controlling transportation infrastructure possibly creates a short board in an urban system. In this study, a macro traffic integrated system was constructed according to a city's economic size distribution and transportation infrastructure. The planning strategy of traffic, industry, space interaction and coordinated development was put forward. Through theoretical model, the evolution mechanism between transportation infrastructure and economic scale distribution was revealed. Starting from the center of the city and inter city level, China's new urbanization strategy was implemented, and a comprehensive transportation system model was built. The traffic planning in Singapore was taken as an example, and the solution to traffic problems such as congestion, traffic jam, and distance was obtained. Practice has proved that the rational and effective urban transportation infrastructure construction can effectively promote the coordinated development of economy and resources, and comprehensively enhance the level of integrated transport services.
Keywords: Transportation Infrastructure, Economic Size Distribution, Evolution Mechanism, Coordinated Optimization.
1. Introduction
With the improvement of global information level, regional exchange has been enhanced, economy has rapidly progressed, and advancements in urbanization and motorization have consequently accelerated. With the rapid growth of a city, economy, space, and population continuously expand, and the number of mega cities in the world increases (Kitamura and Mohamad 2009). The significant increase in urban population likely produces high urban traffic demands, and urban population travel characteristics become evident and implicated in urban economic activity and traffic (Rissel et al. 2013). A large growth in urban population also indicates that the demand for urban traffic is increasing. With fast economic development and population expansion in major cities worldwide, transportation systems must be able to adapt to urban development (Creutzig et al. 2012). As the new core long pole of global economic growth, China experiences a remarkable development of city-scale evolution (Li 2011). The rapid growth of urban population and economy likely promotes the expansion of urban space, and the corresponding transportation infrastructure needs probably imp rove continuously. However, mechanisms on how to arrange a transportation infrastructure network based on urban scale distribution have yet to be determined. With global urbanization, the number of big cities, large cities, and super cities has increased. Urban scale continuously expands, and...
