Strategic Study On Urban Transportation Development

As the concentrated expression of human civilization, in its formation, growth, the city has also produced a series of environmental, traffic and social problems. Traffic congestion is affecting thousands of families day-to-day travel, and restricting urban operating efficiency and the enhancement of city competitiveness, it has become one of the issues that required urgent solution.This paper jumps out of the traditional study ways that only considering the traffic supply and demand, and puts forwards an alternative thought from the perspective of urban structure. Then the paper introduces the basic theories that how urban spatial structure affects transportation structure: monocentric and polycentric, and jobs-housing balance theory. After literature review, the paper does the quantitative analysis using China's major cities' and Shanghai's data respectively. Finally, based on the theoretical analysis and empirical study, the paper tries to build a suitable spatial model, and proposes some strategic direction for China's mega-cities.The whole article is divided into six chapters:The first chapter is introduction, mainly introduces the research background, the choice of research perspective, meaning, main contents and method;Through domestic and international literature review, the second chapter explains whether polycentric structure has better travel efficiency than monocentric structure, further analysis shows that this contradiction resulted from two kinds of polycentric structures which are formed on different mechanism;The third chapter puts forwards the other perspective that how urban spatial structure affects transportation structure: jobs-housing balance theory. First, the paper introduces the concept, measurement, and research scale; then the paper summarizes the contradiction whether jobs-housing balance has important affection on travel;The fourth chapter uses the method of quantitative analysis, inspects the mechanism how urban structure affects transportation structure, explores its law, supplies empirical support for mega-cities traffic relief. Specifically including two aspects: using more than 20 years of 40 samples of urban transport travel information in our country, the paper does the significant test of affection factors of urban travel, and contrasts the conclusion with foreign research; then the paper uses the experience abroad for reference, an indicator is built to measure the jobs-housing balance, the outcome indicates that the jobs-housing balance is getting more and more weakened in Shanghai;Based on theoretical research and empirical findings, the fifth chapter tries to build a spatial model suitable for mega-cities in our country, and proposes some strategic direction;The sixth chapter summarizes main theoretical and empirical research findings, and makes some study prospects.
