System dynamics simulation model for Integrated Price Strategies of Public Transport

The public transport price system, constituting of three subjects of public transport travelers, operators and managers, is the one with complex multi-variable, multi-feedback and non-linearity, and different integrated price strategies have different influences on stakeholders. By adopting the system dynamic, we establish causality graph and flow graph among the variables of public transport price system, and the dynamic model of public transport price system. Through raising or lowering the three index values of public transport subsidy standard, public transport vehicle supply and public transport service price, it could form several of integrated price strategies plans of public transport. Under the background of high and low levels of economic development, and based on the Zhuhai Public Transport Corporation to simulate the Integrated Price Strategies of Public Transport in five situations, it gets the variation trend of government subsidies, public transport business profits and the waiting time. Selecting the indexes of social welfare and ratio of funds utilization, it assesses the implementation effect of different Integrated Price Strategies of Public Transport. The analysis of integrated policies of public transport price provides a reference for the formulation and implementation of the public transport price policy.
