城市客运交通结构生态效用多目标优化模型

Multi-objective Optimization Model for Ecological Utility of Urban Passenger Transport Structure

随着出行需求和出行方式的增多,城市交通结构优化问题亟待解决。文中基于不同交通方式的特性,提出交通效用最大化、生态影响最小化、广义成本最低化的多目标优化模型,并用理想点法对模型求解。通过算例分析,优化后城市客运交通的周转量和分担率更加科学合理,验证了模型的可行性,体现了城市交通可持续发展的理念。

With the increase of travel demand and travel modes, the problem of urban traffic structure optimization needs to be solved urgently. Based on the characteristics of different modes of transportation, a multi-objective optimization model with maximizing traffic utility, minimizing ecological impact and minimizing generalized cost is proposed, and the model is solved with ideal point method. Through the analysis of the example, the turnover and sharing rate of urban passenger traffic after optimization are more scientific and reasonable, which verifies the feasibility of the model and reflects the concept of sustainable development of urban transport.
