UDOT urges LIDAR detection and accessible pedestrian signals to improve safety at signalized intersections
Summary
UDOT presented on accessible pedestrian signals and LIDAR detection to improve safety for vulnerable road users at signalized intersections, saying LIDAR offers more capabilities and cost advantages compared with radar.
Mark Taylor of UDOT Traffic Signals reviewed the importance of accessible pedestrian signals (talkable or wave) and described three key uses of LIDAR detection to improve safety for vulnerable road users at signalized intersections. Taylor said UDOT is moving toward replacing radar detection with LIDAR because LIDAR provides additional capabilities at lower cost.
The presentation emphasized technological approaches to improve crossing safety for pedestrians and people who are blind or have low vision, and framed LIDAR as an operational upgrade in detection systems. The item was presented for information; no formal policy or procurement decision was recorded in the transcript.
