Leading Pedestrian Intervals

Leading Pedestrian Intervals (LPI) give pedestrians a head start to cross the street before cars are given the green light. Pedestrians can better establish their presence in the crosswalk before vehicles have priority to turn right or left.

Leading Pedestrian Intervals have many benefits, including:

  • Increased visibility of crossing pedestrians.
  • Reduced conflicts between pedestrians and vehicles.
  • Increased likelihood of motorists yielding to pedestrians.
  • Enhanced safety for pedestrians who may need more time to cross.
Leading Pedestrian Intervals reduce pedestrian-vehicle crashes at intersections by
