Research On The Methodology And Its Application For Urban Traffic Management And Planning

The urban traffic management is facing a grim situation at present: the traffic demands from the fast growth of all kinds of vehicles and the increase of travel are far beyond the transportation supply provided by existing roads. It's been accepting by the majority of cities that we can relieve the urban traffic problems in terms of improving the management of road and traffic. However, the traffic management can not only be busying with solving a variety of traffic problems raised, it should do forward looking research on traffic management countermeasures strategically along with urban planning and urban traffic planning, that is to work out traffic management plan so as to realize long acting control. Formulating traffic management plan is a critical way to enhance the management level of transportation, it's also the prerequisite and basis of sustainable development of the city.The thesis analyses the necessity to make a management plan of urban road and traffic, introducing the current layout situation of city road and traffic management; considering the investigation on current urban traffic status and its analysis and evaluation, analysis and projection of the demand of city communications, and the design of city road and traffic plan and its evaluation and etc. as the key and vital points of plan of city road and traffic management, expounding the aim, principle, content, grades and process of transportation management program, discussing the analyzing method of demand forecast of the traffic and the application of relevant models of demand of the traffic in the traffic management layout. Finally it discusses and analyses achievements made in the practices of city transportation management planning in China, taking the planning of city road and traffic management in Changsha as an example.Some useful explorations and researches on the planning method of city road and traffic management have been conducted in the article, and a set of scientific, practical planning methods of urban traffic management and their frames of application and research have been summarized. For the formulating of city road and traffic management programs, we should at first investigate, analyze and assess the present situation of city road and traffic control, and then confirm the direction and strategic aim of city transportation development based on the general plan of city social economy development and future transportation demand predicted by models oftransportation demand, finally bring forward the possible future development plan of traffic management and meet the requirements of sustainable development of traffic management by assessment and further optimization plan. The planning methods of city road and traffic control with general practical values have been summed up in the thesis, which is helpful for people to accurately understand the planning methods of city road and traffic control and is a kind of certain reference to plan city road and traffic control. Therefore, the research described in the article is relatively significant both theoretically and practically.
