PBOT has 17 ‘High Crash Network’ projects queued up for construction this year

PBOT will be busy in 2018.

With money in their coffers for the first time in several decades (thanks in large part to the local gas tax and revenue from the state transportation package passed last year), the Portland Bureau of Transportation will be busy in 2018. They recently released a list of 17 projects they plan to construct this year. Nine of them are east of 82nd.

While this isn’t every single thing PBOT will build in 2018, these 17 projects have been singled out because they are on their ‘High Crash Network‘ — a list of streets with “the highest number of reported collisions overall and for people walking and biking in the five‐year period from January 2011 through December 2015.” The projects on this list are queued up for 2018 for a variety of reasons, including a new internal ranking system PBOT uses to flag the most urgent needs.

Keeping to their promise to put data and analysis at the core of their Vision Zero-focused decision-making and prioritization process, PBOT used three metrics to rank intersections on the High Crash Network: Number of fatal and injury crashes between 2011 and 2015; the collision rate (“the number of crashes at an intersection are normalized by considering the number of cars traveling through the intersection”); and the total value of crashes, which assigns a monetary value to the severity of injuries.

They even shared their work. Here’s the formula for collision rate:

Collision Rate = (Crashes/5 years) X (1 year/340 days) X (1/ADT) X 1,000,000

And here’s how they figure out the total value of crashes:

Total Value = # Deaths* Death $ + # Inj A* Inj A $ + # Inj B* Inj B $ + # In C* Inj C $*
(*Death value: $1,500,000; Injury A value: $74,900; Injury B value: $24,00; Injury C value: $13,600)

When those calculations are cross-referenced with other PBOT metrics like “communities of concern”, shovel-readiness and political support, here are the 17 projects that made the build list for 2018:

1. 82nd Avenue
Signal repairs and ADA upgrades at Foster, Woodstock, and Flavel
