城市建设项目交通影响后评价模型

基于后评价原理、建立了城市建设项目交通影响后评价模型,采用权重判断法筛选评价指标,根据单准则AHP构权法确定各指标权重,通过计算偏差率,将各指标归一化。在确定的三级评价指标体系中,一级指标分别为交通需求预测后评价指标、交通改善措施后评价指标、交通可持续性后评价指标;二级指标分别为背景交通需求预测指标、项目交通需求预测指标、区域交通需求预测指标、公共交通需求预测指标、静态交通需求预测指标、土地利用改善指标、交通组织改善措施指标、交通适应性指标、经济影响指标、环境影响指标与社会影响指标。评价结果表明:成都市博远花园住宅项目后评价最大隶属度为0.527 7,评价等级为部分成功,评价结果符合实际。可见,评价指标和模型有效。

Traffic impact post-evaluation model of urban construction project

Based on the post-evaluation principle,a traffic impact post-evaluation(TIPE) model of urban construction project was set up,its indexes were selected by using the method of weight judgment.The weight of each index was determined by using the frame weight method of single criterion AHP,and each index was normalized by calculating deviation rate.In the three-grade evaluation index system of TIPE,the first-grade indexes are traffic demand prediction post-evaluation index,traffic improvement measure post-evaluation index and traffic sustainability post-evaluation index respectively.The second-grade indexes are background traffic demand prediction index,project traffic demand prediction index,regional traffic demand prediction index,public transportation demand prediction index,static traffic demand prediction index,land use improvement index,improvement measure index of traffic organization,traffic adaptability index,economic impact index,environmental impact index and social impact index respectively.The TIPE result of Boyuan Garden in Chengdu City indicates that the maximal membership degree is 0.527 7,the evaluation grade is partly successful,and the result is practical.So,the evaluation index system and model are effective.
