The tables below identify the intersections in the City of Portland with the highest numbers of reported collisions overall and for people walking and biking in the five‐year period from January 2012 through December 2016.

Rankings for the overall list reflect three metrics: total number of crashes, collision rate, and total value of collisions. Walking and biking rankings are based on the total number of crashes, then by severity.

Ranking details and methodology

This document lists and prioritizes intersections in the City of Portland with the highest number of reported fatal and injury crashes in the five-year period from January 2012 through December 2016.

The 2016 High Crash Intersection (HCI) List includes only fatal and injury crashes (property damage only crashes are excluded from the list), supporting the City’s Vision Zero goal of eliminating fatal and serious injury crashes in the City of Portland by 2025. Intersections have been identified and prioritized by number, severity and frequency of fatal and injury crashes.

The 2016 High Crash Intersection (HCI) List for Pedestrians and Bicycles includes the 20 intersections with the highest number of pedestrian crashes and the 20 intersections with the highest number of bicycle crashes. These lists include all pedestrian and bicycle crashes, including property damage only, since property damage only crashes involving pedestrians and bicycle riders are rare.

METHODOLOGY – 2016 High Crash Intersection List

Each intersection was ranked based on the three metrics below in the five-year period from 2012 to 2016. The rankings for each metric were added together and sorted in ascending order to create an index that ranks our high crash locations. Two High Crash Intersection Listings are provided, one sorted by ranking and one sorted alphabetically. There are 4 new locations on this year's list that PBOT will evaluate for improvements.

1. Number of Fatal and Injury Crashes

This is the number of fatal and injury crashes coded to an intersection within the five-year period from January 1, 2012 to December 31, 2016.

2. Collision Rate

Number of crashes coded to an intersection are normalized by considering the number of cars traveling through the intersection. The calculation for the collision rate (collisions per million entering vehicles) is below:

Collision Rate = (Crashes/5 years) X (1 year/365 days) X (1/ADT*) X 1,000,000

*ADT (average daily traffic) is the number of vehicles entering the intersection daily.

3. Severity of Crashes

Severity of crashes is represented by the total economic value of a crash, figured by assigning monetary value to the severity of crash related injuries. The value of each crash is figured by multiplying the number of crash related fatalities and/or injury types by the values below. The number of fatalities and injuries are sustained injuries, not number of crashes. Monetary values are obtained from the National Safety Council (2015.)

Total Value = # Fatals* Fatal $ + # Inj A* Inj A $ + # Inj B* Inj B $ + # In C* Inj C $

METHODOLOGY - 2016 High Crash Intersection (HCI) List for Pedestrians and Bicycles

Each intersection was ranked based on total number and severity of pedestrian-involved or bicycle-involved crashes. Due to limited data, collision rate is not included in the methodology. Intersections with the same number and severity of crashes share the same ranking.

PBOT will investigate locations on the Pedestrian and Bicycle lists that do not already have a proposed or funded project.

This report is compiled from data supplied by the Oregon Department of Transportation, Transportation Safety Division, Crash Analysis and Reporting Unit, from records originally received by the Oregon Department of Motor Vehicles. Due to under-reporting of collisions, this list should not be considered to represent all collisions occurring at the intersections listed. The City of Portland, Bureau of Transportation analyzed the data and prepared the resulting report.
