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.
The use of intelligent transportation systems (ITS) technology is one method that UDOT uses to improve safety. ITS
devices include variable message signs (VMS), vehicle detection, and other electronic systems that convey
information to drivers or sense traffic conditions. UDOT is working to deploy ITS technology on the state roadway
system where it can be an effective means of reducing crashes and crash severity.
UDOT commissioned a scan tour and research study to identify potential safety-related ITS devices and practices in
use around the US that could be adapted to Utah’s roadway system. 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 safety-related ITS applications in Utah.
The research team emailed a list of survey questions about safety-related ITS applications to safety and research
staff at other state DOTs around the county. A total of 33 responses to the initial survey were received, representing
input from 25 states and the Canadian province of British Columbia. Responses were used to select Iowa and
Minnesota as scan tour destinations.
