Modeling on the Structral Optimization of Passenger Transport System in Urban

Abstract

The structure of comprehensive passenger transportation system in urban determines the development direction of urban transport, it is significance to guide residents to travel, reduce the energy consumption, build harmonious traffic. It is started from the analysis on the composition and characteristics of passenger transport system in urban, take the traffic function utility maximization as the objective, considering the passengers demand constraints, roads resource constraints, energy consuming constraints, emission constraints and the each mode development plan constraints, establish the structure optimization model on passenger transport system in urban, combined with the actual data in Harbin, standardized model parameters, solved the optimal structure, and compared with the status data, the study shows that: in the comprehensive passenger transportation system of harbin, the propotion of public transport and walking is low, while the private car, bicycles and taxis is high, the targeted recommendations for improvement is proposed.
