Enhance children safety in crosswalks at (4) signalized intersections:
Separate pedestrian intervals and left turning vehicles
Add exclusive left-turn signal phasing to existing left-turn lane
Convert existing shared left-through lane to left-turn only lane with protected-only and flashing yellow
arrow (FYA) signal phase
Implement a signal timing strategy to give pedestrians a head start to enter the crosswalk before
parallel right turning vehicle traffic receives a green light
Install Leading Pedestrian Intervals (LPI) – WALK intervals come up a few seconds before a green light
Upgrade existing pedestrian push buttons to Accessible Pedestrian Signal (APS) system that comply with
Americans with Disabilities Act (ADA) and Public Right-of-Way Accessibility Guidelines (PROWAG)
Install LED Display that illuminates in coordination with WALK/Flashing Don’t Walk intervals
Replace existing static signs with LED-based signs for right turning vehicles to stop for pedestrians
Install traffic cameras for traffic safety performance monitoring and measures
