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

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 Preliminary Site List: Using maps of pedestrian generators, crashes, and stakeholder nominated sites, identify approximately top 50 locations appropriate for pedestrian improvements

Step #2-Prioritize Sites: Using all five factors, each with their own individual weightings, score each site to determine relative priority

Step #3-Re-evaluate: Using this methodology, the sites list was then reviewed to ensure that the outputs maintained consistency with project goals.

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 laneso Traffic volumeo Speed limit

Crosswalks: US ExampleCrosswalk Research

• 2002 “The Zegeer study” Marked vs. unmarked Two-lane roads

o No difference in pedestrian crash rate

Multilane roadso 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 treatmentso Red beacon displayso Flashing beaconso In-roadway lightso Warning signs / markingso 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)

• Neighborhood traffic calming

• Junctions

• Roundabouts

• Principles: Speed kills

o Narrow laneso Reduce turn radiio Traffic calming

Limit exposure:o Reduce crossing distanceso Safe crossings at a reasonable distanceo Channelize if necessary
