Safety Investment Program (SIP)

Program Discontinuted!

Please note:
  This program was discontinued after 2012 and is no longer used for ranking safety projects.  The history of the SIP Program is available as reference only.

The SIP was originally developed to help focus safety investments on pavement preservation projects to where they are most needed.  The Safety Investment Program is based on three basic premises:
  1. That the most effective use of safety dollars to save lives is to invest in areas where the most people are being killed or seriously injured.

  2. Investments in safety should be focused more specifically on the countermeasures that address the most prevalent crash types and provide the highest benefit to cost ratio.

  3. Safety funding for cost effective safety improvements to preservation projects with category 3, 4, 5 segments are a priority.

Formulation and Map

In order to determine these categories, crash data for the most recent three years is incorporated into a GIS map, which shows different colors for five mile segments based on the following five categories:  
  • Category 1:    0 (no) fatal or injury A (serious) crashes;

  • Category 2:    1 to 2 fatal or injury A crashes;

  • Category 3:    3 to 5 fatal or injury A crashes;

  • Category 4:    6 to 9 fatal or injury A crashes

  • Category 5:    10 or more fatal or injury A crashes.

SIP for Project Planning

Preservation projects with category 1 and 2 segments have a “pave mainly” focus.  Using Preservation funds, mandatory design features must be incorporated as per the ODOT Highway Design Manual and low-cost safety mitigation measures may be considered. Typically Safety funds would not be used on these projects unless there is a high priority SPIS site within the project limits. Fewer safety features are designed into these projects because of the lack of recorded history of safety problems.
Preservation projects with category 3, 4, and 5 segments must be reviewed for possible countermeasures to improve safety.  Designers should review the segment for high priority SPIS locations within the segment.  They should also review possible countermeasures for the prevailing type(s) of crashes in the segment and estimate the benefit/cost ratio for the possible countermeasures.  This ensures that improvements with the greatest payback in crash prevention are considered. Countermeasures in SIP Category 4 or 5 segments are eligible for Highway Safety Program funding even if the benefit/cost analysis does not meet the minimum ratio of 1.0.  SIP Category 3 segments require a benefit/cost ratio of 1.0 or greater. See the Highway Safety Program Guide for further information and criteria for Highway Safety funding.
