为了更好地对公路网建设的交通效益进行评价,构建了公路网交通效益指标体系,并采用数据包络分析(DEA)方法进行相对有效性评价与分析.鉴于全排序的客观要求,在CCR的基础上提出了基于系统潜能损失的结果修正模型,并引入了最劣决策单元对其进行DEA再评价.以9个公路网为蓝本采集指标数据,进行了基于DEA结果修正模型的交通效益评价,并与选取的9个公路网的实际运行情况做了对比分析. In order to evaluate the traffic benefit of highway network construction better, the index system of traffic efficiency of highway network is established, and the relative effectiveness evaluation and analysis are carried out by DEA method.According to the objective requirement of full-ranking, , A modified model based on the potential loss of the system is proposed, and the worst decision-making unit is introduced to reassess DEA.According to the nine road networks, the index data are collected, and the traffic benefit evaluation based on the modified DEA model , And compared with the actual operation of the selected 9 road network.
