Traffic Counting

This Page provides access to the web version of the Oregon State Highway Transportation Volume Tables, or TVT, including the Permanent Traffic Recorder section and the Interchange Ramp Volume Diagrams. The Highway numbers seen in these pages are the Oregon Department of Transportation highway numbers. These numbers are not what you would see on road side signs when driving on our highways. For those not familiar with our highway numbering system see the Highway Cross Reference Table.

We also provide traffic volumes, flow maps, trends, manual counts and vehicle class on state highways to Federal, State, Local, Private and Public constituents.

We prepared a document to address the question of pandemic impacts on future transportation planning:

The Oregon Traffic Monitoring System (OTMS) is an online interactive tool where you can access count data. Count locations are featured on a map. You can zoom in, zoom out, and pan to an area of interest. Or if you know a Location ID already you can look it up that way using the Search box. The available data includes common annual statistics, such as Annual Average Daily Traffic (AADT) and truck percentages. At most sites, it also allows you to access more detailed count data. The OTMS pages are optimized for use in a Chrome browser.

The public can go to Transportation Data Management System to access the public portal. This is limited to data years that have been finalized. Newer data is still subject to edits.

ODOT employees can go to Transportation Data Management System to access the internal portal. The first time you log in, you will have to use the blue button that says ‘Log in with ADFS’ and then enter your ODOT login data. In subsequent visits, this blue button will take you straight in to the TCDS.

In the public and internal portals, you have access to three modules. The Traffic Count Database System (TCDS) module is the main data system with our straightaway counts and includes the raw data and annual statistics. The Turning Movement Count (TMC) module holds our intersection counts. The Non-Motorized Database System (NMDS) module holds counts from permanent or short term bicycle and pedestrian counts. Below you will find documents to help with various aspects of the system. But each of the modules has a Help button at the top with access to much information. The Help button in the TCDS is context sensitive. So if you hit that when you first open the TCDS, it will give you good information on ways to search for locations and their data.

A mobile-friendly public version called Traffic Viewer is also available.

​We collect classification data on all state highways and classify vehicles according to the FHWA Scheme-F 13 vehicle guidelines FHWA Vehicle Classification Definitions. This presentation of the data differs from the Volume Tables in that it is presented by range rather than location. The mile point shown is not where the count was taken, but rather the beginning of the range the count is considered to represent. The data presented in the classification report also includes the AADT, design hour factor and ton mileage factor.

For additional classification information on a State Highway, please contact ODOT Traffic Monitoring.

State Highway Volume & Classification Reports

​Vehicle Miles of Travel, or VMT is the sum of distances traveled by all motor vehicles in a specified system of highways for a given period of time. The VMT for each road section is calculated by multiplying the average daily traffic, or ADT by the length of the road section and the length of the time period. Those section VMTs are summed to calculate the VMT for a road or road system.

​Many times people are interested in traffic counts inside of cities or particular counties. Most of our focus is on the state highway system so we have a limited amount of information on some of these specific volumes.
