基于DEA／AHP的河谷型城市轨道交通线网规划方案评价

Evaluation of Route Network Planning in Valley Cities Base on DEA/AHP Method

河谷型城市由于其特殊的地理形态，城市交通较为混乱，河谷型城市轨道交通线网规划是城市的百年大计，城市轨道交通线网规划方案评价也显得尤为重要。本文采用DEA／AHP两阶段模型对河谷型城市轨道交通线网规划方案进行综合评价。该模型第一阶段使用DEA方法计算所有线网规划之间相对有效性，以构造AHP的判断矩阵。第二阶段对判断矩阵进行AHP计算并作全排序优选，最后给出了排序结果。

Valley cities due to its special geography, urban is the city＇s centenary policy, Evaluating for route network AHP two stage models are used to comprehensively evaluate traffic is chaotic, Valley cities＇ route network planning planning is also appears especially important. DEA/ all planning. This evaluation model use DEA method in first stage to calculate relative coefficient between two planning to calculate will be carried out in second stage based on judgment matrix compose the judgment matrix of AHP. AHP and give sequencing.
