Study On Optimization Of Hohhot Public Transportation Network

Urban public transportation is the harbinger of social production, the key of a city function to operate and an important window of the material civilization and spiritual civilization of a city. Therefore, developing urban public transportation is widely concerned by all the world. Roundly scanning the existing situation of public transportation of Hohhot, adopting the advanced optimization theories and methods of urban bus network of other countries, the reasonable objective function is worked out, and optimization model is established by studying constraints and objectives from parts of urban public transportation (nodes and routes of network). Reasonable routes of urban public transportation are selected out by factors, such as constraints to nodes, route length and nonlinear route of network. Network of urban public transportation is constituted by certain organized way of different nodes and routes. Forecast model of transition vehicle (bus) allocation and forecast model of the passenger demand for transportation of Hohhot are worked out by linear programming ,the gray system , optimum theory etc. The mode of network of urban public transportation in Hohhot is forecast. Furthermore, the optimization model of network is established according to the existing situation of public transportation of Hohhot .
