Research on the Problems Existing in China's Transportation Structure and Optimization Policy

At present, highway transportation is the main mode of transportation in China, but highway transportation has the problem of high cost, energy consumption and pollution. Although China has put forward the development policy of public transit railway, it still needs some time to achieve this goal. This paper studies the traffic structure from the middle level; combined with empirical analysis, it is concluded that railway transport has a greater impact on national income than road transport; the existing problems and causes of China's transportation structure are analyzed and the optimization policies are put forward.
