摘　　要： 智能运输系统(ITS)项目社会经济影响评价对于ITS项目开发、实施决策具有重要的理论价值和现实意义。本文以电子收费系统(ETC)项目为研究对象,运用基于虚拟决策单元的数据包络分析方法(DEA)设计了ETC项目社会经济影响综合评价模型,并通过基于交通仿真软件模拟设计的评价方案给出评价案例。评价结果表明,本文提出的基于虚拟决策单元的DEA方法不仅弥补了传统DEA模型不能有效区分有效决策单元的不足,而且综合考虑了成本效益分析法难以币值化的一些效益影响,因此其评价结果更加全面、更加符合客观实际情况。 The socio-economic impact evaluation for Intelligent Transportation System(ITS) projects has important theoretic value and realistic significance for the implementation of ITS projects. By making in-depth study on Electronic Toll Collection(ETC) projects, this paper presents a comprehensive model of data envelopment analysis(DEA) based on a fictitious DMU for the socio-economic impact evaluation of ETC projects and an example is introduced based on simulated program. The evaluation results show that the established DEA model not only makes up for the shortcoming of the traditional DEA′s failure to effectively differentiate the efficient DMUs but also takes into account of some benefits and impacts difficult to be quantified in monetary terms in Cost-Benefit Analysis,so the evaluation results should be more overall and more objective.
