    • Presentation Summary • Background • Pedestrian safety process • Nuances of working abroad • Questions
    • Quick Poll • Who has worked internationally? • Who has worked in the UAE?
    • BackgroundWhere is Al Ain? 121.5° W 56° E 177.5° Half way around the world (almost)
    • BackgroundWhere is Al Ain?
    • BackgroundWhere is Al Ain?

    • BackgroundCommon Ingredients of a Dangerous Pedestrian Environment • Low density land use pattern • Large roadways • Lack of safe crossings • High vehicle speeds • Dangerous driver behavior • Ineffective pedestrian safety treatments
    • BackgroundIngredients of a Dangerous Pedestrian Environment • Low density land use pattern  National housing policy  Low gas prices School $1.46 Mosque per gallon School 1.2 units/acre Source: www.maps.google.com
    • BackgroundIngredients of a Dangerous Pedestrian Environment • Large, high-speed roadways Multiple-threat collision Source: http://guide.saferoutesinfo.org
    • BackgroundIngredients of a Dangerous Pedestrian Environment • Large roadways with long blocks 1 mile Source: www.maps.google.com
    • BackgroundIngredients of a Dangerous Pedestrian Environment • Large roadways 60 km/hr = 50 mi/hr
    • BackgroundIngredients of a Dangerous Pedestrian Environment • Large roadways

    • BackgroundPedestrian Safety: USA vs. UAE Source: Dangerous by Design 2011 Transportation for America
    • BackgroundPedestrian Safety: USA vs. UAE • Al Ain  2009 Population = 374,000  2008 Pedestrian fatalities = 28  Avg. annual pedestrian deaths per 100,000 = 7.5 Source: Dangerous by Design 2011 Transportation for America
    • BackgroundIngredients of a Dangerous Pedestrian Environment Low density land use Large roadways Lack of safe crossings Dangerous driver behavior
    • BackgroundImprovement of Pedestrian Safety and Movement in Al Ain and Suburbs • Summer 2010 – Al Ain Municipality hires project team  Background: where is walking occurring, where have collisions occurred • November/December 2010 –team visits Al Ain for two weeks  Stakeholder meetings  Site visits • January 2011 – July 2011 –team develops recommendations • August 2011 – team submits draft report
    • Pedestrian Safety ProcessFlowchart Define problem Identify priority locations Develop targeted improvements
    • Site SelectionWhere to Focus Planning Efforts Approx 200 sq. miles
    • Site Selection: US ExampleWalkFirst Project | San Francisco
    • Site Selection: US ExamplePedestrian Activity The WalkFirst Program takes into account seven different factors to serve as indicators for pedestrian activity  Access / need to walk (transit and walking mode share)  Transit ridership (daily transit boardings)  Population density (residential and job density)  Pedestrian generators (schools, medical facilities, retail, senior centers, etc)  Vulnerable populations  Income  Street slope
    • Site Selection: US ExamplePedestrian Activity
    • Site Selection: US ExamplePedestrian Safety
    • Replicating this methodology in the UAE“Same but Different” While the basic approach is the same, the level of data available and other cultural norms require a slightly different approach; our team used five input categories throughout our process. 1. Pedestrian generators 2. Pedestrian crashes and collisions 3. Estimated and observed pedestrian volumes 4. Level of potential improvement 5. Local stakeholder priority
    • Replicating this methodology in the UAEDesired Deliverables The desired goal was to have a prioritized list of 46 sites. The following process was used to come up with this list.Step #1- Develop Step #2-Prioritize Sites: Step #3-Re-evaluate:Preliminary Site List: Using all five factors, Using this methodology,Using maps of pedestrian each with their own the sites list was thengenerators, crashes, and individual weightings, reviewed to ensure thatstakeholder nominated score each site to the outputs maintainedsites, identify determine relative priority consistency with projectapproximately top 50 goals.locations appropriate forpedestrian improvements

    • Pedestrian Safety ProcessFlowchart Define problem Identify priority locations Develop targeted improvements
    • ImprovementsCommon Themes • Midblock crossings • Neighborhood traffic calming • Junctions • Roundabouts
    • ImprovementsSite Visits Mean Everything • See through the “eyes of a pedestrian” • Document everything • Use aerial maps • Take photos of everything
    • Crosswalks: US ExampleCrosswalk Research • Herms, Bruce. (1972) Pedestrian crosswalk study: accidents in painted and unpainted crosswalks. Transportation Research Record, 406.  “The San Diego study”  Marked crosswalks vs. unmarked crossways  Increased incidence of pedestrian collisions in marked crosswalks  Did not differentiate between: o Number of lanes o Traffic volume o Speed limit
    • Crosswalks: US ExampleCrosswalk Research • 2002  “The Zegeer study”  Marked vs. unmarked  Two-lane roads o No difference in pedestrian crash rate  Multilane roads o Marked crosswalk alone associated with higher crash rate
    • Crosswalks: US ExampleCrosswalk Research • “The Zegeer study” Key: C = Candidate sites for marked crosswalks; P = Possible increase in pedestrian crashes may occur if crosswalks are marked without other pedestrian enhancements; N = Marked crosswalks alone are insufficient.
    • Crosswalks: US ExampleCrosswalk Research • “The Zegeer study” • LOS A-C • LOS D-E • LOS F
    • Crosswalks: US ExampleCrosswalk Research • 2006  “NCHRP 562”  Researches effectiveness of different crosswalk treatments o Red beacon displays o Flashing beacons o In-roadway lights o Warning signs / markings o Crosswalk markings  Measured yield compliance
    • Crosswalks: Replicating this research in the UAEApplying USA Research to the UAE • What treatments will generate yield compliance?  Roadway characteristics  Driver characteristics • Environmental factors • Crossings not crosswalks
    • CrosswalksRecommendations • 2-lane roadway: marked crosswalk • 4-lane roadway:  Raised crosswalk  Rapid Rectangular Flashing Beacon (RRFB) • 6-lane roadway:  Pedestrian signal  HAWK beacon (High-intensity Activated crossWalK beacon)
    • CrosswalksRecommendations • 4-lane roadway:  Raised crosswalk  Rapid Rectangular Flashing Beacon (RRFB) RRFB Source: www.spotdevices.com Raised crosswalk: before and after
    • CrosswalksRecommendations • 4-lane roadway
    • CrosswalksRecommendations • 6-lane roadway:  Pedestrian signal  HAWK beacon (High-intensity Activated crossWalK beacon) HAWK Beacon Source: www.roswellgov.com
    • CrosswalksRecommendations • 6-lane roadway
    • Improvements• Neighborhood traffic calming• Junctions• Roundabouts• Principles:  Speed kills o Narrow lanes o Reduce turn radii o Traffic calming  Limit exposure: o Reduce crossing distances o Safe crossings at a reasonable distance o Channelize if necessary
