GoLocal ranks Oregon's most dangerous intersections
To rank the most dangerous intersections in Oregon, GoLocalPDX began with the state’s listings of high-crash intersections and roads.
GoLocalPDX crunched data provided by the Oregon Department of Transportation from its Safety Priority Index System (SPIS).
The index looks at which areas are the most worthy of the state's attention given the frequency of crashes, crash rate and severity of crashes, ODOT officials said. The state uses the SPIS to help engineers determine areas most in need of fixing and where the state should prioritize spending.
GoLocalPDX's researchers used the state accident data and assessed four factors: total number of accidents, fatalities, injuries, and property damage only.
GoLocalPDX created a ranking formula that weighted each of the three categories of crashes based on the "danger" of the outcome (fatalities were weighted more than injuries, which were weighted more than property damage only), which yielded the final ranking order.
Our system differs from the state's in that ODOT also calculates crash rates, which is a per capita ranking that takes overall traffic volume into consideration.
