Leading Pedestrian Interval (LPI)

Cross first. An LPI gives people walking a 3–7 second head start before cars get a green light.

Educational sign about leading pedestrian intervals.

What is it?

A Leading Pedestrian Interval is a signal timing feature that lets people begin crossing the street before drivers are allowed to move. The walk signal turns on early so people become more visible in the crosswalk.

How to Use It

  1. Wait for the WALK signal to appear before stepping into the street.
  2. Begin crossing as soon as WALK appears—this is your "head start".
  3. Stay alert for turning vehicles and make eye contact when possible.

Why It Matters

LPIs reduce crashes by making people in the crosswalk easier for drivers to see. Giving people a few extra seconds to enter the street before cars move improves visibility, lowers turning conflicts, and increases safety for everyone.

Statistics

Where You’ll See It in Madison

You can find LPIs at many busy intersections, especially where there are high pedestrian volumes or turning conflicts. Examples include:

  • Downtown and campus-area intersections
  • Locations with high foot traffic
  • BRT Stations
  • Corridors with heavy turning movements

Tips for Drivers

  • Yield to people in the crosswalk—they legally enter first during the LPI.
  • Expect people to already be in the street when your light turns green.
  • Turn with care, especially on right turns.
