The Research On The Disequilibrium Characteristics Of Urban Traffic Supply And Demand

In the urban traffic system which is complex and giant, the traffic supply and demand are the two most important parts, and the coordination of them is the premise for health and rapid development of urban traffic. The numerous and varied factors which affect the traffic supply and demand cause the relationship between traffic supply and demand is always in a disequilibrium state, which also enhance the traffic congestion. Since the study on the relationship between urban traffic supply and demand is significantly important.Based on the present situation of urban transport development, the defects of the traditional traffic plan theory are pointed out, and the disequilibrium traffic planning theory is proposed to improvement the defects in this thesis. This thesis focuses on the study of disequilibrium characteristics of supply and demand in urban transport system. Firstly, this thesis pointed out that the equilibrium is the special status of the disequilibrium by using the basic theory of the urban traffic supply and demand and the interaction of supply and demand with the economic equilibrium concept; secondly, analyses the market regulation mechanism on basis of traveling market; thirdly, establishes traveling market model, describes the unity of urban traffic's equilibrium and disequilibrium using variable inequalities, and studies the characteristics of disequilibrium solutions; and then establishes the disequilibrium degree model to describe the extent of the disequilibrium, and gives the case analysis; finally, this thesis proposes several measures to coordinate the supply-demand relationship for urban traffic and some problem requiring further studies. This thesis can be the decision-making reference of department for transport planning and management.
