A Leading Pedestrian Interval (LPI) typically gives pedestrians a 3–7 second head start when entering an intersection with a corresponding green signal in the same direction of travel.
LPIs enhance the visibility of pedestrians in the intersection and reinforce their right-of-way over turning vehicles, especially in locations with a history of conflict.
LPIs have been shown to reduce pedestrian-vehicle collisions as much as 60% at treated intersections.
Pedestrians are given a minimum 3–7 second head start entering the intersection.
Through and turning traffic are given the green light. Turning traffic yields to pedestrians already in the crosswalk.
