Filter by Keyword8 report(s) found with signalized intersections in the keywords field 1 - 8 of 8 This study evaluated the approach-level safety performance of left-turn phases at signalized intersections, including permissive, protected-permissive (PPLT), protected indications, and flashing yellow arrow (FYA). Data collection included exact dates of traffic signal changes, high-resolution datasets... The goal of this study is to evaluate light rail priority strategies along the 400 S / 500 S corridor in Salt Lake County through analyzing benefits and impacts of the priority on transit and vehicular traffic through microsimulation. The results show that the existing priority strategies have no impacts... With ever-increasing traffic demand and price of fossil fuels public transit becomes more popular transportation mode than ever before, especially in the fast growing regions such as Salt Lake City Metropolitan Region. Wasatch Front Regional Council (WFRC) (a local Metropolitan Planning Organization)... In 2005, the Utah Department of Transportation (UDOT) installed the Sydney Coordinated Adaptive Traffic System (SCATS) in Park City, Utah, on its network of 14 signalized intersections. A field evaluation compared previous time-of-day actuated-coordinated signal timings with those dynamically computed... This research evaluates the effectiveness of the future Utah Department of Transportation (UDOT) adaptive signal control system on the arterial street network in Park City, Utah, that experiences both everyday and unpredictable changes in traffic flow. This report contains the planned methodology for... A study of collisions occurring at intersections along State routes in Utah was conducted. The number of crashes, the crash severity score and, for selected locations, the crash rate were determined and "ranked" for intersections within the Utah Department of Transportation's Region 1, Region 2, Region... UTL compared the intersections with an Advanced Warning System (AWS) to an intersection without AWS. They found that the AWS in St. George was not effective in reducing the number of drivers in DZs. Although 90% of drivers responded positively by reducing their speed when the signal was flashing, most... This study examines signal timing in inclement weather conditions. With the completion of the Utah DOT's Advanced Traffic Management System (ATMS), UDOT will have the capability to change signal timing plans from a central location by communicating with each controller through fiber optic technology.... |
