Introduction

Introduction

  • High Intensity Activated CrossWalK

  • Motivation

    • Portland Crashes (1985 – 2002)

    • Increase in bicycle traffic

    • Commitment to walking and biking

Pedestrians Crashes

3% Injuries

29 % Fatalities

Introduction cont

Introduction – cont.

  • Crashes at non – signalized intersections

    • Bikes and Peds have trouble finding gaps

    • Motorists on major streets do not yield or stop

  • Options to reduce crashes

    • Median refuge islands, painted crosswalks

      • Low compliance rate

    • Install traffic signal

      • Not warranted, higher delay, increase in emissions

    • HAWK

Analysis pedestrian bicycle delay

Analysis – Pedestrian & Bicycle Delay

  • Delay data not collected from video because of camera angle

  • HAWK activates as soon as button is pressed

  • Min time between activations – 30 sec

  • Observed and collected data in PM on February 22, 2011
