Abstract:

Crashes are random events and low traffic volumes therefore don’t always make crash hot-spot ; identification possible. This project has used extensive data collection and analysis for a large sample ; of Oregon’s low volume roads to develop a risk index that expresses the crash risk for different road ; geometries and roadside features as well as crash history and traffic exposure. This crash risk index can ; then be a proactive means of identifying potentially risky locations where safety treatments might be ; best targeted. The economic analysis completed as part of this effort can be used in conjunction with ; the risk index when determining which safety treatments may result in the highest return on investment ; for agency safety improvement funds. This report includes a review of literature related to features ; effecting crash risk and other past risk index efforts, the data collection and analysis methods used in ; quantifying risks, the establishment of the crash risk index, an economic feasibility analysis showing ; which treatments may be the best options for Oregon’s low volume roads, and a few case studies ; highlighting the use of the crash risk index on three samples of Oregon’s low volume roadways.
