Summary

Pedestrians jaywalk more when facing longer signal delays. Traffic planners can use this data to design safer pedestrian crossing signals and reduce traffic injuries.

Area of Science:

  • Traffic Safety
  • Human Behavior
  • Urban Planning

Background:

  • Thousands of pedestrians are injured or killed annually in the U.S.
  • Jaywalking at busy intersections elevates pedestrian injury risk from automobiles.

Purpose of the Study:

  • Investigate pedestrian jaywalking behaviors.
  • Examine how temporal conditions influence compliance with pedestrian walk signals.

Main Methods:

  • Conducted studies at a three-street intersection.
  • Manipulated walk/no-walk signal timing to create differential delays.
  • Observed pedestrian crossing behaviors in clockwise and counterclockwise directions.

Main Results:

  • Significantly more pedestrians jaywalked when facing longer signal delays.
  • Jaywalking rates differed between directions with varying signal timings.

Conclusions:

  • Pedestrian signal timing significantly impacts jaywalking behavior.
  • Findings can inform traffic planners in developing improved pedestrian signal systems to enhance safety.
