Evaluation of Pedestrian Safety Countermeasures—Summary of Results, Conclusions and Lessons Learned

Peyton McLeod

Kelley Klaver Pecheux, Ph.D.
Science Applications International Corporation (SAIC)

Slide 2

SAIC Team’s Role

  • Conduct an independent national evaluation
  • Compile and summarize teams' results
  • Conduct a cross-cutting analysis
  • Identify lessons learned

Slide 3

Independent National Evaluation

  • Evaluate zone / area-wide combined impacts of countermeasures (as opposed to site-specific, individual impacts)
    • Identified intersections within deployments zones/areas
    • Collected before and after data (safety, mobility, customer satisfaction)

Slide 4

Collins Avenue Zone, Miami

Data Collection Site

Slide 5

Independent National Evaluation--Findings

  • Mixed (non significant, counterintuitive results, inconsistent)
  • No conclusive carry-over impacts / trends found, especially looking across the locations

Slide 6

Summary of Results and Cross-cutting Analysis

  • Compile and summarize results from three locations
  • Compare results across locations

Slide 8

Challenges

  • Similar, but not identical countermeasures
  • Same countermeasure applied somewhat differently
  • MOEs measured somewhat differently

Slide 9

Findings/Conclusions

  • Summarize findings for non cross-cutting countermeasures

  • Assess effectiveness of cross-cutting countermeasures

  • Group countermeasures in terms of effectiveness
    • High
    • Medium
    • Low

Slide 10

High Effectiveness

  • Leading pedestrian phase
  • Pedestrian countdown signals
  • Rectangular rapid flashing beacons
  • In-street signs
  • Call buttons that confirm the press
  • Danish offset (combined w/ high-visibility Xwalk, advance yield markings, YIELD HERE TO PEDESTRIANS sign

Slide 11

Medium/Mixed Effectiveness

  • Activated flashing beacons
  • Electronic no turn on red (NTOR) sign
  • Elimination of permissive left turns
  • Portable speed trailers

Slide 12

Low Effectiveness

  • High visibility crosswalks
  • Advance stop lines
  • "LOOK" pavement stencils
  • "Turning traffic yield to pedestrians" signs
  • Pedestrian zone signs

Slide 13

Effectiveness Dependent on Application

  • Median refuge island
  • Dynamic lighting
  • Automated pedestrian detection (to activate or extend pedestrian crossing phase)

Slide 14

Identify Lessons Learned

Major steps in the project included:

  • Establishing and maintaining a multi-agency team to oversee and guide the project
  • Identifying safety and mobility problems, including potential contributing factors to crashes
  • Selecting countermeasures corresponding to the problems identified
  • Obtaining funding and support for improvements
  • Procuring, deploying, and maintaining the countermeasures
  • Evaluating the effectiveness of the countermeasures

Slide 15

General Lessons Learned

  • Assemble a diverse set of project partners to address the range of issues that might arise during the study
  • Implement regular communication and participation mechanisms for project partners from project kick-off
  • Use a variety of methods/sources to understand problems and to determine causes of crashes at prominent pedestrian crash locations
  • Begin the program by implementing low-cost countermeasures for the greatest potential of widespread use

Slide 16

General Lessons Learned (cont'd)

  • Pursue a variety of funding sources for the pedestrian safety program
  • Do not underestimate the complexity of procurement
  • Budget ample time for deployment and coordinate with the appropriate jurisdictions
  • Consider how the timing of countermeasure deployment may impact the experimental design and evaluation
  • Consider the unique aspects of collecting and reducing pedestrian safety data

Slide 17

Countermeasure-specific Lessons Learned

  • Strategically place in-street pedestrian signs to reduce the chance of them being hit by vehicles and to maximize their effectiveness
  • Consider the technical issues surrounding the use of automated pedestrian detection
  • Translate public service messages into multiple languages to successfully reach non-English speaking populations
  • Be prepared to demonstrate to concerned traffic engineers that the electronic NTOR sign will not significantly disrupt traffic progression along a corridor. Work with the local electrical department and vendors to make sure everything is in place for success.
