Traffic Speed, Volume & Classification Studies

2025 Fall Traffic Counts have been completed as of October 2025.

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 and have been conducted every 3 years, or as needed. Starting in 2023, the City now collects data on one-third of the study locations each year. This means that each location will be evaluated every three years, maintaining the previous schedule of data collection.

Oregon City Studies

For ease of use, we have categorized our studies by street names. Please refer to the alphabetical listings in the subpages of this section 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: These are the least common counts. The counter is set up to attempt to classify each vehicle according to number and configuration of axles
