Summary
This document is the 2021 Annual Report for Oregon’s Highway Safety Improvement Program (HSIP), administered by the Oregon Department of Transportation (ODOT). The report addresses the federal mandate under the Fixing America’s Surface Transportation (FAST) Act to significantly reduce traffic fatalities and serious injuries on all public roads. The primary motivation is to implement a data-driven, jurisdictionally blind strategy that prioritizes infrastructure improvements over educational or enforcement activities, which are handled separately. ODOT achieves this through the All Roads Transportation Safety (ARTS) Program, which integrates both state-owned highways and local, tribal, and non-state roadways into a unified safety improvement framework. The methodology employed by the ARTS Program utilizes two distinct approaches: hotspot analysis and systemic screening. The hotspot approach identifies specific locations with a history of fatal or serious injury crashes using the Safety Priority Index System (SPIS), while the systemic approach applies proven, low-cost countermeasures across the network based on risk factors. Systemic efforts focus on three emphasis areas—roadway departure, intersection, and pedestrian/bicycle safety—which accounted for approximately 85% of fatal and serious injury crashes between 2015 and 2019. Projects are prioritized using a Benefit-Cost Ratio, and only countermeasures from the ODOT-approved Crash Reduction Factor list are utilized. Funding is allocated to five ODOT regions based on the proportion of recent fatal and serious injury crashes, with a 50/50 split between hotspot and systemic components within each region. Additionally, funds are divided between state highways (49%) and local jurisdictions (51%) to reflect crash distribution patterns. ODOT provides free consultant services to local agencies to support project selection and data analysis. The report details the program’s administrative structure, noting that the Traffic-Roadway Engineering Section manages HSIP policies, while regional offices handle project delivery. A comprehensive FHWA review confirmed the program’s strengths, including its focus on severe crashes and robust network screening. However, the review identified six key actions for improvement: enhancing crash data timeliness, strengthening safety analyses, integrating ARTS knowledge into broader transportation safety plans, streamlining project delivery, addressing funding gaps for project size, and developing comprehensive metrics for effectiveness. Recent administrative changes include implementing a $500,000 minimum for federal projects to improve delivery efficiency and separating local and state funding streams to allow for more strategic project selection. The significance of this report lies in its documentation of Oregon’s compliance with federal HSIP requirements and its evolution toward a more efficient, data-centric safety program. By mandating jurisdictional blindness and focusing on cost-effective countermeasures, ODOT aims to maximize the impact of limited resources. The report highlights ongoing efforts to improve data processing and project delivery speed, reflecting a commitment to continuous improvement in reducing traffic fatalities and serious injuries across all public roads in the state.
Key finding
The Oregon HSIP utilizes a competitive, data-driven ARTS Program to fund infrastructure projects on all public roads, with a recent FHWA review confirming its strengths and recommending improvements in data processing and project delivery efficiency.
