• 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.
