This map mimics a typical traffic map but represents the number of driving under the influence (DUI) arrests along each street over the course of 10 years. Red, orange, yellow, and green are used to denote relative frequencies of DUIs.
You can see the highest density of DUI arrests in Old Town, particularly along Burnside and 3rd Ave. Zooming all the way in and you can even see the detail of the satellite imagery showing the buildings.

The Source Data
The crime data can be downloaded from CivicApps, Portland’s data portal. Here’s a direct link to the FTP site that contains multiple years of data. The crime data was filtered to only include DUIs. As always when looking at crime data, remember this is where the most people are arrested, which isn’t necessarily the same as where the most people are actually driving drunk.
The satellite imagery was from the National Agriculture Imagery Program (NAIP) and was downloaded through the Oregon Imagery Explorer.
