交通指数,也称交通拥堵指数或交通运行指数,是综合反映道路网畅通或拥堵的概念性指数值。交通指数取值范围为0~10,分为五个级别(即“畅通”、“基本畅通”、“轻度拥堵”、“中度拥堵”、“严重拥堵”),数值越高表明交通拥堵状况越严重。
最后对城市交通指数的实用性进行评估。
Finally, we assess the applicability of urban transport index.
目前,国内对于城市交通系统的综合评价的研究还处于初级阶段,交通指数方面的研究更少。
At present, the research about the comprehensive evaluation of domestic urban transport system is still in its initial stage, the research about traffic index is less.
所以本论文对我国交通指数编制的理论和方法进行研究和探讨,试图以交通指数来评价城市交通系统的综合状况。
Therefore, this paper puts emphasis on the research about the theory and compute methods of traffic index. We try to use transport index to evaluate the development of the urban transport system.
