摘要: 在分析城市道路交通供、需系统构成的基础上, 采用范围法、目标法构建了两系统发展水平评价指标体系, 引入供需系统协调发展度的概念, 给出了判定系统协调发展水平及趋势的定量化评价方法。供需评价结果与实际情况相符, 表明该方法可行。Abstract: Based on the supply-demand theory, this paper constructed the evaluation indices of supply-demand system of urban road traffic, proposed a concept of coordination development level of supply-demand system and a quantitative evaluation method of determining the coordination development level. An example show that this method can reflect the real circumstance, which shows the method is feasible.
