Optimization and Sustainability of Urban Transportation Structures in China
Definition of sustainable transportation:
Sustainable transport systems, also known as green transport, refer to all modes of transport that have a low impact on the environment, including walking, cycling, transit-oriented development, green vehicles, car-sharing, and the building and protection of urban transport systems through the conservation of energy, urban space and the promotion of healthy lifestyles. At the same time, sustainable transportation systems can have additional positive impacts that contribute positively to protecting the environment and maintaining the social and economic sustainability of the communities in which they are located.

Optimization of urban transport structure in China
Urban transportation in China is closely related to urban population, economy and environment. First of all, urban transportation can realize the circulation of goods and promote urban economic development. It can also meet the living and traveling needs of urban residents and improve the quality of life and work efficiency. However, on the other hand, urban transportation also causes a series of environmental problems and resource consumption problems in Chinese cities, such as air pollution, noise pollution, land occupation and so on, which makes transportation in China during the period of development an unsustainable development mode.
Therefore, in recent years, the urban transportation system has been continuously optimized, paying more attention to the protection of the environment and the use of resources, and of course, it also needs sufficient transportation security as a prerequisite. Urban transport planning itself is the organization of urban transport system security and rational design. By updating the urban traffic structure and making reasonable use of space and environmental resources, it can optimize the relationship between supply and demand of urban traffic. The stable optimization of urban transportation has a positive effect on the development of the whole city, and it is expected to achieve the common development of urban transportation and economy, environment and resources.
Sustainable Development of Transportation in China
For the Chinese Government, sustainable development is an inevitable choice for social prosperity and progress. Our common wish is for a healthy, green and robust development of the transportation industry. China is committed to connecting with the world on sustainable transport development and promoting global transport cooperation. In addition, it was doing its utmost to improve the modern integrated transportation system, while also enhancing scientific and technological innovation in the transportation industry and developing diversified green and low-carbon transportation modes.
In recent years, China’s sustainable transport development concepts and practices have centered on eight themes: infrastructure, transport equipment, transport services, openness and cooperation, safety and emergency response, science and technology innovation, green development and transport governance. At the same time, in accordance with these themes, China has advanced the construction of modern sustainable transportation and is currently building a modern comprehensive three-dimensional transportation network to optimize the layout, structure, functions and system integration.
Analysis of Sustainable Transportation Strategies：
The first is the widening of the space for urban development, which is integrated with the urban transportation network through changes in land-use patterns and high-density urban structures. At the same time, in terms of sustainable development, priority is given to the development of public transportation, with the establishment of more subways, light railways and urban railways. Compress individual demand, reduce the traffic flow of private cars, and encourage the use of new energy vehicles in order to achieve the reduction of traffic emission pollution problems. In addition, the reconstruction of transportation transfer hubs, regular bus, bicycle transportation and rapid transit interchange, the construction of modern urban traffic management system, the overall control of urban traffic.
Sustainable transportation has different implementation strategies in different countries, all of which are centered on sustainability and energy conservation and environmental protection for transportation development. In today’s society, sustainable transportation must be combined with scientific and technological innovation to change the traditional concepts of transportation and transportation modes, and to achieve a complete renewal of the urban transportation system.
