ACCOMPLISHMENTS

Most signals will detect bicycles, as well as vehicles and motorcycles, waiting at a red light.

Real time management of traffic signal operations is deployed at 99% (previously over 90%) of UDOT’s intersections.

UDOT has equipped all traffic signals with generator plugs so power can be restored quickly and easily during outages.

Reflectorized yellow tape is now placed around traffic signal backplates to help increase signal transparency.

Generator plugs are being installed on all traffic signals so power can be restored quickly and easily during power outages.

SIGNAL MAINTENANCE & OPERATIONS

The Traffic Signal Maintenance and Operations Program optimizes mobility, improves safety and strengthens the economy by improving traffic flow, reducing stops, increasing the visibility of traffic signals, and optimizing traffic signal timing for special events and businesses.

Recent initiatives:

Traffic Signal Event Management - UDOT has reduced delay during events by working with local venues and deploying signal timing plans to handle changes in travel demand.

Increased Proactive Maintenance - Potential problems are addressed before road users experience inconvenience.

Real-Time Traffic Signal Operations Management - Volumes, speeds, and other metrics are collected in real-time. UDOT was one of the first to use these new tools and has been instrumental in helping dozens of agencies nationally and world wide and throughout the world to use this technology. The Federal Highway Administration has added the program to their Every Day Counts Initiative to help others follow UDOT’s path.

Uniform Guidelines for Traffic Signal Timing - all 47 Utah jurisdictions owning traffic signals are updating traffic signal timing parameters for consistency across the state.

Extra Pedestrian Time - a special key switch that provides extra time for crossing guards has been installed at over 40 intersections.
