8:30 AM to 5:00 PM: Cause, Effect, and Intervention: Current and Future Directions in Road Safety Research

Workshop 126

Forrest M. Council, University of North Carolina, presiding

Sponsored by:
Safety Data, Analysis and Evaluation Committee (ANB20)
Statistical Methodology and Statistical Computer Software in Transportation Research Committee (ABJ80)
Development of the Highway Safety Manual Task Force (ANB25T)

Note: The purpose of this workshop is to be a forum for discussing current road safety research approaches, assessing their strengths and weaknesses and suggesting promising future directions. The workshop should be of interest to researchers, those who manage and fund road safety research programs, and those who make use of road safety research results.
Much of what we think we know about the safety effect of design and operational decisions or about the effect of interventions is based not on ‘designed experiments’ but on ‘observational studies’; studies that make use of what data can be assembled after the fact. The morning session will be devoted to the question “Can One Come To Cause-Effect Conclusions in Observational Road Safety Studies?”

Reliable knowledge about the safety effect of design and operational decisions or about the effect of interventions accumulates only slowly. Perhaps progress could be accelerated if novel directions were pursued. The afternoon session will be devoted to the question “What Research Approaches Hold Promise?”
