交通方式结构对城市可持续发展的影响分析

The impact analysis of passenger traffic modes on the urban sustainable development

随着居民出行需求的多样化,从城市可持续发展的角度出发,构造了交通方式对城市可持续发展的评价模型,确定交通方式对城市可持续发展各方面的影响指标,如城市GDP增长、房地产开发、服务行业发展等,运用层次分析法对各交通方式影响城市发展的程度进行了综合评价,结合了评价结果,以城市可持续发展最大效率为目标,以城市交通需求、道路系统容量、环境容量等因素为约束条件建立了交通方式结构优化模型,并以苏州市为例,提出促进其发展的合理客运交通方式结构。

Because of the diversification of resident trip demand and the requirements of urban sustainable development, a new model for traffic mode sustainability assessing was made. The impact indexes of traffic mode on urban sustainable development, e. g. the growth of city＇ s GDP, the development of real estate and the service industry, etc. , was determined. In the paper the mathematic methods was applied to evaluate the impact extent of traffic mode on urban development. Two types of impact assessment results were obtained. It helped to accurately orientate the traffic modes. Then, with the evaluation results, the mathematical programming model of transport system mode optimization was made, too. Its abjective was to obtain maximum efficiency of the urban sustainable development. The urban passenger trip demand,capacity of the road system and environmental factors etc were regarded as its constraints. Finally, the model was applied to address the rational passenger transport system mode in Suzhou.
