    • Abstract:
      The Utah Department of Transportation (UDOT) has long been on the forefront of nationwide efforts to improve roadway safety. Their safety focus encompasses infrastructure improvements as well as non-infrastructure elements such as education and enforcement. Wrong-way driving on limited access freeways has been a growing safety concern in Utah and across the United States in recent years. While Utah experiences lower rates of impaired driving (a leading contributing factor to wrong-way driving events) than its peer states, it still occurs frequently enough to merit attention from UDOT researchers and engineers. The severity of wrong-way crashes tends to be much higher than for other types of crashes because of the speeds involved and their propensity to yield head-on impacts. As a result, wrong-way crashes represent a disproportionate share of severe crashes relative to total crashes of that type. With this background in mind, UDOT embarked on a research project and scan tour to study potential wrong-way driving countermeasures for deployment in Utah. Staff members from key UDOT divisions and other partner agencies with an interest in wrong-way driving issues were included in the technical advisory Committee. Committee members were instrumental in helping to determine the research focus and scan tour locations. This report documents the process used to determine scan tour locations, describes the information learned during the scan tour visits, and then presents recommendations for using the information to inform wrong-way driving mitigation efforts in Utah.
