• Abstract:
  This report documents a research effort to quantify the safety performance of driveways in the State of Oregon. In ; particular, this research effort focuses on driveways located adjacent to principal arterial state highways with urban or ; rural designations. This report includes safety performance functions (SPFs) that can be used to evaluate the safety ; impacts of various access management and driveway-related configurations on Oregon arterial corridors. The project ; team developed these safety metrics using statistical models and methodologies similar to those outlined in the ; Highway Safety Manual (HSM) published in 2010 by the American Association of State Highway and Transportation ; Officials (AASHTO). Instead of using a base condition SPF that included only segment length and traffic volume and ; then would need companion CMFs to fully analyze a corridor, the project team developed full model SPFs that do not ; require any additional adjustments. The resulting models varied for urban versus rural conditions, but type of land use ; and traffic volume were two consistently significant variables observed for both models. A companion “smart ; spreadsheet” accompanies this report to assist readers with implementation of the procedure.
