The All Roads Transportation Safety Program is designed to address safety needs on all public roads in Oregon. Only by collaborating with local road jurisdictions can the Oregon Department of Transportation expect to:
The program will be data driven to achieve the greatest benefits in crash reduction and should be blind to jurisdiction.

2018 ARTS Program Summary Report
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:
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 documents listed below explain the All Roads Transportation Safety Program in greater detail.
The entire program is data-driven and based on benefit cost analysis of key factors including the amount of crashes, crash reduction factors and project costs.
The program prioritizes hotspot and systemic projects based on benefit cost ratios - which locations will get the most crash reduction for the cost of the project.
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.
The CRF list and supplement are listed below. Also listed is a form for submitting proposed CRFs not included in the list.
The traditional approach to safety is to identify “hotspot” locations where a high concentration of crashes occur, and 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.
The systemic measures have been proven to successfully reduce the occurrence of fatal and serious injury crashes. The process for systemic projects is an application-based process. Local agencies and ODOT regions submit applications for systemic projects in three focus areas:
Projects are prioritized based on benefit cost ratio for roadway departure and intersections projects, and cost-effectiveness index for pedestrian/bicycle projects.
Benefit Cost Analysis Form - Used in the applications of roadway departure and intersection systemic countermeasures.
ARTS Application Form - For use with ODOT's Highway Safety Improvement Program (HSIP) All Roads Transportation Safety (ARTS) Program. This application should be used for both hotspot and systemic project types.
Cost-Effectiveness Index Analysis spreadsheet - Used for projects applying pedestrian/bicycle systemic countermeasures.
Cost Estimator Worksheet - Used in the applications for all three areas of systemic improvements.
