Analysis Method of Two-Way Balance of Transportation Supply and Demand in a Regional Corridor

The result of transportation demand analysis always differs too much from the real operational outcome, especially in the application aspect of regional transportation demand analysis, which lacks necessary model updates. Research on regional transportation has significant value in application. This paper declares the limitations of traditional transportation forecast methods, theoretically and applicably. It then discusses a two-way balance of transportation supply and demand and states the countereffect of traffic demand due to transportation supply conditions in short/long periods. The built system dynamic model is based on a balance of supply and demand in the transportation corridor. Key variables - like economic potential energy, transportation supply demand ratio, and environmental influence level - are discussed. Finally, the model is proved in a case study.
