This data 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 did the analysis of the data and prepared the resulting report. Each location was ranked based on metrics in the four year period (2011‐2014.) The individual metric ranks were added to together and sorted in ascending order to create our list of high collision locations.
1. Total Number of Crashes
This is the total number of crashes within the four year period from January 1, 2011 to December 31, 2014.
2. Collision Rate
This metric normalizes crash data by considering the number of cars traveling through the intersection. The equation used to compute the collision rate (collisions per million entering vehicles) for these locations is as follows:
ADT is a 24‐hour volume count of vehicles entering the intersection in vehicles per day. The volume used is considered to be approximate for a number of reasons; daily variation in counts, the count may not have been taken specifically at the intersection, the count may not be recent enough to reflect current conditions, etc.
3. Total Value of Collisions
The crash values integrate crash severity into the High Crash Listing. This is calculated using National Safety Council monetary crash values (2013) and multiplying these by the total number of each fatality, injury type or property damage only (PDO) crash. Note that the number of fatalities and injuries are sustained injuries, not number of crashes.
Total Value = # Fatals* Fatal $ + # Inj A* Inj A $ + # Inj B* Inj B $ + # In C* Inj C $ + # PDO*PDO $
