This is the final Report from Phase I of the 2003 Utah Department of Transportation (UDOT) Benchmark Study. The study involved two phases and the USU research team produced two final reports, one for each phase of the research project, and an overarching Executive Summary. The purposes of the 2003 UDOT Benchmark Study conducted by Utah State University (USU) were to provide the Utah Department of Transportation (UDOT) with information for use in its statewide, long-range transportation plan and to provide benchmark data for tracking trends over time. The study was conducted jointly by the Institute for Outdoor Recreation and Tourism and the Natural Resource and Environment Policy Program, which are both administered through the Department of Environment and Society in the College of Natural Resources at Utah State University.
