通常,在反映一个城市规划、建设和管理状况时用人均道路、居住、园林绿地等面积,人均产值等等指标来表示。其一般为实物形式(空间形态)或价值形式的指标。但是,我认为,在重视高速度、高效率的现代社会中,考察一个城市规划、建设和管理的现代化水平如何,必须引进时间形式的指标。交通时距,是指城市居民从出行起点到达终点在时间上的消耗(它包括采用合适交通工具运行及起终端必要步行时间在内)。它与空间距离概念的区别在于,它不是从空间的角度去衡量间距,而是从时间的范围去考察出行起点到终点距离的量度概念。城镇居民出行的交 Usually, when reflecting the status of a city’s planning, construction and management, it is indicated by such indicators as per capita road area, residential area, garden area and per capita output value. It is generally an indicator in physical form (spatial form) or value form. However, in my opinion, in the modern society that emphasizes high speed and high efficiency, it is imperative to introduce time-scale indicators of the modernization of a city’s planning, construction and management.
