  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

  6. Study Area Burnside St & 41st Ave Civil & Environmental Engineering

  8. Study Area - 41st Avenue Civil & Environmental Engineering

  9. Study Area - Burnside St Civil & Environmental Engineering

  10. Study Area – Intersection Diagram Study Area Source: FHWA Experimentation #4-298(E) Modified HAWK Signal and Bike Signal - Draft Report Civil & Environmental Engineering

  11. HAWK Westbound Burnside Eastbound Burnside Civil & Environmental Engineering

  12. HAWK Display Flashing Yellow Solid Yellow Solid Red Flashing Red Civil & Environmental Engineering

  13. Bike and Pedestrian Displays Don’t Walk Walk Flashing Don’t Walk Civil & Environmental Engineering

  14. Display Sequence Source: FHWA Experimentation #4-298(E) Modified HAWK Signal and Bike Signal - Draft Report 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
