• Abstract:
  The Safety Investment Program (SIP) was originally called the Statewide Transportation Improvement Program -
  
  Safety Investment Program (STIP-SIP). The concept of the program was first discussed in October 1997 and the
  
  program was adopted by the Oregon Transportation Commission in August 1998. The concept for the program
  
  grew out of a cost-effective approach to pavement preservation projects that set out to maximize the impact of
  
  money spent on highway safety, based on crash reduction factors. Safety projects were to be selected based on high
  
  crash locations as identified by the Safety Priority Index System (SPIS) and SIP Category ratings of five-mile
  
  sections. This research evaluated the SIP Policy from the perspective of: 1) an overall program for safety
  
  improvement projects, 2) a guiding policy when safety improvements are planned as part of other project work,
  
  and 3) a component integrated with the highway design procedures for resurfacing, restoration, or rehabilitation
  
  (3R) projects. The research included two levels of evaluation; the first evaluation was done as part of the systemic
  
  evaluation, while the second was a project-level evaluation. The systematic evaluation revealed that, in general,
  
  projects where safety funds were used resulted in a net decrease in total crashes as well as severe and fatal crashes;
  
  however, these benefits were not realized for all locations or all work types. The detailed review of the 24 mixed
  
  safety-preservation projects highlighted some of the challenges of successfully implementing the SIP Policy. It was
  
  clear that the SIP Policy has not been applied consistently to mixed projects. In particular, the variety of design
  
  and, to a lesser extent, the funding eligibility scores, highlight the variety of policy interpretations. The projectlevel
  
  evaluation concluded that the most important project element to improve safety performance was the specific
  
  identification of a safety problem. Recommendations were made on improved documentation procedures at the
  
  project level as well as strategies to improve overall policy compliance.
