Evaluation of HAWK Signal Effectiveness at 41st Ave & Burnside St in Portland, OR

This report evaluates the effectiveness of High-Intensity Activated CrossWALK (HAWK) signals at the intersection of 41st Avenue and East Burnside Street in Portland, Oregon. It analyzes area characteristics, data from pedestrian and bicycle counts, and violation statistics to assess the impact of HAWK signals on pedestrian safety. Recommendations for signal improvements and public education are provided, alongside acknowledgments to contributors. The study aims to enhance safety for cyclists and pedestrians while addressing crash patterns and compliance rates.

  1. HAWK EvaluationNE/SE 41st Ave & E Burnside St Sirisha Kothuri William Farley Kimber Miller Aaron Rieck Civil & Environmental Engineering

  2. Outline • Introduction • Area Characteristics • Data • Analysis • Conclusions • Recommendations • Acknowledgements Civil & Environmental Engineering

  3. 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 Civil & Environmental Engineering

  4. 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 Civil & Environmental Engineering

  5. MUTCD & HAWK Locations • 2009 MUTCD • Includes information on ped hybrid beacon • Application, design and operation • Installed locations • Portland, OR • 41st & Burnside • 18th & Sandy • Tucson, AZ • Other cities (Washington DC, Salt Lake City ) Civil & Environmental Engineering

  15. Data • Video data available for 4 days in May 2009 • Analyzed time periods • PM Peak (5 – 6 PM) on Thursday, 5/14/2009 • AM Peak (8 – 9 AM) on Friday, 5/15/2009 • Type of data gathered • Counts: Pedestrian & Bicyclist • Violations: Pedestrian, Bicyclist, & Motor vehicles • Delay: Pedestrian & Bicyclist Civil & Environmental Engineering

  16. Intersection via Video Civil & Environmental Engineering

  17. 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 Civil & Environmental Engineering

  18. Analysis – Pedestrian Counts Civil & Environmental Engineering

  19. Analysis – Pedestrian Violations Total AM => 23 Total PM => 24 Civil & Environmental Engineering

  20. Analysis - Bicycle Counts Civil & Environmental Engineering

  21. Analysis – Bicycle Violations Total AM => 44 Total PM => 84 Civil & Environmental Engineering

  22. Analysis – Vehicle Movement Violations Counts Civil & Environmental Engineering

  23. Analysis – Vehicle Violation Specifics HAWK Activations AM => 28 PM => 41 Civil & Environmental Engineering

  24. Crashes Source: FHWA Experimentation #4-298(E) Modified HAWK Signal and Bike Signal -Draft Report Source: FHWA “Safety Effectiveness of the HAWK Pedestrian Crossing Treatment” .. Civil & Environmental Engineering

  25. Conclusions • Primary objective of using the HAWK system • System usage at study location • Violations were observed for all modes • Crashes for the study location Civil & Environmental Engineering

  26. Recommendations • Improvements to the signal on Burnside • Improvements to the signal on 41st • Increased public education • Further research on crash patterns and effectiveness Civil & Environmental Engineering
