The All Roads Transportation Safety Program addresses safety needs on all public roads in Oregon. Only by collaborating with local road jurisdictions can the Oregon Department of Transportation expect to:
- Increase awareness of safety on all roads.
- Promote best practices for infrastructure safety.
- Compliment behavioral safety efforts.
- Focus limited resources to reduce fatal and serious injury crashes in the state of Oregon.
Frequently Asked Questions
The ARTS Program is data driven to achieve the greatest benefits in crash reduction and should be blind to jurisdiction.

More about the ARTS Program
In 2012, ODOT reached out to the League of Oregon Cities and the Association of Oregon Counties to establish principles for a jurisdictionally blind program. The resulting
Memorandum of Understanding documents the agreement between the agencies to apply federal Highway Safety Improvement Program funding to roads managed by Oregon counties and cities.
The MOU outlines the principles agreed to and some of the federal requirements for HSIP funds, a few of which are:
- The program goal is to reduce fatal and serious injury crashes.
- The program must include all public roads.
- The program is data-driven and blind to jurisdiction.
Implementing the All Roads Transportation Safety Program takes careful planning to deliver a regional project selection process that addresses safety needs on all public roads.
The All Roads Transportation Safety Program prioritizes hotspot and systemic projects based on benefit cost ratios. In practice, this means the ARTS Program prioritizes project locations that will get the most crash reduction for the cost of the project.
The program is data-driven and based on benefit cost analysis of key factors including the amount of crashes, crash reduction factors and project costs.
Program Background and Project Selection Overview Presentation
Overview of Project Selection Criteria
The traditional approach to safety is to identify “hotspot” locations, where a high concentration of crashes occur, then identify and implement measures to reduce the number of crashes occurring at that location.
ODOT typically uses the
Safety Priority Index System to identify potential hotspot problems on the state highway system.
SPIS is a flagging tool that compares the number of crashes on the entire roadway network across Oregon, including city streets, county roads and state highways.
It generates two annual reports -- on-state highway and off-state highway -- listing public roadway segments with a calculated SPIS score.
The SPIS score is based on crash rate, frequency and severity over the prior three calendar years. The higher the SPIS score, the higher the potential safety need for the identified roadway segment.
SPIS can be used to identify roadway segments that can benefit from potential safety improvements.
The systemic approach identifies a few proven low-cost measures to implement widely, then put those measures into effect where there is evidence that they would be most useful.
Why use a systemic approach?
The systemic measures have been proven to successfully reduce the occurrence of fatal and serious injury crashes.
Local agencies and ODOT regions submit applications for systemic projects in three focus areas:
Projects are prioritized based on the following:
- Benefit cost ratio for roadway departure and intersections projects.
- Cost-effectiveness index for pedestrian/bicycle projects.
Forms and Tools
A crash reduction factor provides an estimate of the percent decrease in crashes for a given countermeasure.
ODOT provides a fixed set of CRFs allowing all projects to be evaluated consistently and fairly throughout the project selection process.Crash Reduction Factor Manual
Can you think of a crash reduction factor we've missed, or maybe there is a CRF you would like us to further review or investigate?
