ABSTRACT: The Federal Railroad Administration requested the Volpe National Transportation Systems Center to assess ten sites in depth that used the Traffic Separation Study (TSS) process. The assessment involved a quantitative and qualitative analysis of the impact of the process used at each site and an evaluation of community involvement activities. Information was collected through a review of relevant documentation and interviews conducted with key stakeholders from each site. The sites were assessed over a fiveyear period during which time the process further evolved and improved. The TSS is a collaborative partnership among NCDOT Rail Division; railroad engineers; engineering consulting firms; mayors and other municipal officials; police, fire, and other emergency services staff; and community residents, including abutters to the site, land developers, and motorists. It includes a comprehensive evaluation of traffic patterns at highway-rail grade crossings to assess existing safety conditions and determine the need for improvements and/or elimination of crossings based on specific criteria that, in effect, serve as state guidelines.
