  • Introduction
  • Objectives
  • Methodology
  • Developing the database & tool
  • Simple case study
  • Discussion
introduction
Introduction
  • Challenge in disseminating research results to the practitioner
    • accessible and easy to use
    • still provide the depth and guidance
  • Online tool can be easier
    • interactive nature
    • specific information displayed
    • content can also be continuously updated
project objectives
Project Objectives
  • Conduct evaluation of research
    • comprehensive set of countermeasures
    • expected effectiveness
    • references
  • Deliver results
    • traditional format
    • online planning and design tool
    • not just a “table” – include discussion
project methodology
Project Methodology
  • Assemble countermeasure catalog
    • review/edit/synthesize
  • Find studies for each countermeasure
  • Systematic review process
    • ranking of study quality
    • summary of studies for each countermeasure
  • Derive CRFs from synthesis of studies
countermeasure catalog
Countermeasure Catalog
  • Original ODOT list
    • 91 countermeasures (really 67)
    • deletions recommended: 19
  • Similar efforts nationally
    • NCHRP 17-25, HSM Part II, Safety Analyst
  • Approximately 200 countermeasures identified
    • list reviewed and refined to 94
estimating crash reduction factors
Estimating Crash Reduction Factors
  • Research reviewed
    • limited countermeasures with quality research available
    • used NCHRP 17-25 for consistency
  • Our categories
    • Countermeasures with Robust Research
    • Countermeasures with Limited Research
    • Countermeasures with Discussion Only

    • SE: Car dealership
    • SW: Lawn
  • Western & Pacific RR
discussion
Discussion
  • Useful – anecdotal feedback positive
  • Discussion and documentation
    • transparency is important
  • Online search tool could help less experienced safety professional
  • As this tool continues to develop, it can be customized rather easily
