摘　　要：以高速公路入口匝道-可变限速联合控制系统为研究对象,运用基于虚拟决策单元的数据包络分析方法(Data Envelope Analysis,DEA)设计了系统综合评价模型,并针对某实际道路网络条件给出了仿真评价案例。评价结果表明,利用基于虚拟决策单元的DEA模型对该联合控制系统进行评价,能有效地弥补传统DEA模型不能充分区分决策单元有效性的不足,为交通运输部门的管理者提供了有效的决策依据。With the study of a combined system of on-ramp and variable speed limits, this paper presents a comprehensive evaluation model based on the Data Envelopment Analysis （DEA） by introducing fictitious DMU for the system projects. A simulation example is introduced with the traffic network condition of a practical road, The evaluation results show that the established DEA model fully surmounts the weakness that the traditional DEA does not completely differentiate the efficient DMUs, and provides a more efficient analysis tool for the policymaker of the transportation department.
