Leading Pedestrian Intervals and Addressing the Impact on Safety

When: Thursday, April 4, 2024 | 3:00 - 4:00 PM ET

This webinar is led by the ITE Traffic Engineering Council.

Webinar Description:

Pedestrian fatalities in the United States increased from just over 4,000 per year in 2009 to over 7,300 per year in 2021 and 2022 - the highest levels since 1982. About of quarter of these fatalities occur at intersections. One safety counter-measure for vehicle-pedestrian crashes that has become popular is Leading Pedestrian Intervals (LPIs).

A leading pedestrian interval, or pedestrian head start, is typically described as a 3-7 seconds of advance time for pedestrians to begin walking before traffic can begin moving, so that the pedestrians become more visible to conflicting turning movements. The application showed promise in a 2002 study in Las Vegas. Over the past 20 years, leading pedestrian intervals have been gaining popularity as a pedestrian safety enhancement.

This webinar will explore the latest research in the effectiveness of LPI as a safety counter-measure, and will feature the results of an October 2018 FHWA study, which has demonstrated that LPIs can be expected to reduce vehicle-pedestrian crashes by 13 percent.

Learning Objectives:

  • Discuss the expected effectiveness of LPIs
  • Employ guidance on the best implementation strategies for LPIs
  • Examine how widespread the use of LPIs are
  • Distinguish the appropriate timing for LPIs
