Study Of Urban Road Traffic Supply And Demand Equilibrium Theory

With the speed-up of the urbanization and the mobilization, the discrepancy that the urban traffic supply can't satisfy the demand is becoming increasingly obvious. It results in urban traffic problem and restrains the development of social economy. In this paper, in order to crystallize research object, the connotation level and stage of urban traffic supply-demand balance are defined and discussed firstly. Then, the balance chain is put forward and applied to reveal the dynamic development law of the supply-demand balance. Meanwhile, based on analyzing the relationship between the traffic supply and demand, the composition and action circuit of urban traffic supply-demand balance system are studied. Next, the spatial distribution pattern of urban is researched into according to the OD component. In term of the level and characteristic of traffic demand, the development stages of it are also questioned. Moreover, the concept of traffic supply is scanned afresh in order that some wrong opinions are corrected. Based on studying rational traffic structure, road network layout structure classification structure and service level, the urban traffic supply-demand balance model which is related to four parameters preceding is built. At last, the analytical frame model is applied to set up a model to diagnose the problem of urban traffic supply-demand balance in light of the impact factors. Based on the consequence and the character of urbanization development grade, the paper explains the stages of supply-demand measures, divides the layers of supply-demand and gives solutions in detail.
