Passenger Transportation Structure Optimization Model Based on User Optimum

Abstract

Passenger transportation structure has a great influence on efficiency of regional comprehensive traffic system. Rationalization and optimization of passenger transportation structure is one of important means of improving its validity. From static point of view, an optimization idea of user optimum in the premise of meeting the demand of regional passenger transportation was put forward. According to this idea, optimization model of passenger transportation structure based on resource constraints is built. With the example of the passenger transportation system in the three cities of Harbin, Daqing and Yichun, model is calculated using the software Matlab. Then the optimized proportions of the comprehensive passenger transportation of the three cities are given. Using fuzzy comprehensive evaluation method, the passenger transportation structures before and after optimization are evaluated. The evaluation method is adopted to estimate the passenger transportation structure which is both from optimization model and the actual situation. Through comparison and analysis of the estimation results, it demonstrated the effectiveness of optimization model.
