Rational Allocation of Passenger Transportation Structures in a Metropolitan Area

摘要

In light of the rapid development of urbanization, this essay mainly studies the new type of metropolitan area during city evolution and researches about the rational allocation of intercity passenger transportation in metropolitan areas. Based on analyzing the mode and the demand characteristics of the metropolitan transportation, in terms of both sides of transportation supply and demand, establishes the objective function, maximizing the passenger transport efficiency and minimizing residents' cost of travelling, and builds the Multi-objective programming model using restraining variables such as economy, environment, efficiency and service in the passenger transport system. To solve the question above, we apply genetic algorithm (GA) and get the most reasonable transportation structure in metropolitan in sustainable development. Given the same city transportation capacity, different travelling mode split can result in different utilization efficiency, with which we can assess the rationality of the transportation allocation. Finally, we take the Wuhan metropolitan as an example and use the model to allocate the rational transportation structure from Wuhan city to Xiaogan city.
