Research on the Disequilibrium Characteristics of Urban Traffic Supply and Demand

Based on the interactions between urban traffic supply and demand, this paper analyzes the regulation mechanism with the moderator variable of the price and quantity separately under the travel market. With the conception of urban roadpsilas space-time resource, this paper definitions the traffic demand and traffic supply, and establishes the disequilibrium degree model to describe the extent of the disequilibrium. The numerical example demonstration shows that the disequilibrium model proposed in this paper is operable for urban transportation planning and management.
