摘要：	Many state departments of transportation (DOTs) operate safety service patrols (SSPs) as part of their incident management programs. The primary objectives of SSPs are to minimize the duration of freeway incidents, restore full capacity of the freeway by removing incidents faster, and help reduce risks to motorists and response personnel. To become and remain competitive for funding, freeway SSPs must be able to quantify and articulate their value, relative to cost. Although estimates of the benefits of these programs have been quantified in other areas of the United States, the Virginia Department of Transportation (VDOT) does not have a documented methodology for quantifying the benefits of its SSP programs. This study sought to develop such a methodology. The scope of the study involved a state-of-the-practice literature review, the development of the methodology, and an application of the methodology to VDOT's Northern Virginia (NOVA) SSP program as a case study. The case study also included an examination of the NOVA SSP operations and a performance analysis of its incident responses.
