Traffic Speed, Volume and Classification Studies
Hwy 99E in 1943

The City of Oregon City has been conducting traffic volume studies since 1978. We have historical traffic volume counts from 1978, 1980, 1989, 1990, as well as more current ones. Any of our historic studies are available for review. Our most recent studies are available online (see below) and will be conducted every 3 years, or as needed.

If you have any questions about the studies or would like to view historical data, please contact Katie Englund at 503.496.1567.

OREGON CITY STUDIES:  For ease of use, we have categorized our studies by street names.  Please refer to the alphabetical listings below to find information on a particular street.  Note that not all streets have studies available.

Different kinds of traffic studies are performed and identified as follows:


Volume:  This is the most common type of traffic count which records the number of vehicles.


Speed:  This is a traffic count which measures the speed in which vehicles are traveling.


Classification:  Classification: These are the least common counts. The counter is set up to attempt to classify each vehicle according to number and configuration of axles.
