2031 Highway Future Volume Table
The 2031 Future Highway Volume Table is created using data from the Transportation Volume Tables (TVT), which are maintained by the Transportation Systems Monitoring Unit's Traffic Counting Program. The Future Volumes table includes all of the individual highway count locations in the TVT sorted by highway number and milepoint. NOTE that the highway number is the Department's Internal highway number, not the route (OR/US/I) number. Highway numbers and Route numbers can be cross-referenced using the traffic monitoring cross-reference.
The future volumes are estimates only and local growth patterns and comprehensive plans may affect the actual outcome. The growth rates calculated from the Future Volumes Table are only a beginning point of estimating future volumes. Engineering judgment needs to be applied to the numbers. For information on how to use this table, see Section 4.4.1 of the Analysis Procedures Manual.

Seasonal Trend Table
The Seasonal Trend Table can also be used to estimate seasonal traffic count adjustments. For information on how to use this table, see Section 4.4.2 of the Analysis Procedures Manual (APM). The Seasonal Factor Table is updated on a yearly basis, typically in June. Seasonal Trend Table factors are calculated using previous full year of ATR data.
Oregon Travel and Activity Survey
The Oregon Modeling Steering Committee has recently embarked on a new survey effort to collect data used for model development and analysis. The Oregon Travel and Activity Survey (OTAS) will collect household activity data across the state of Oregon. This survey will be conducted over several years and may include specialized surveys to learn more about specific issues, such as recreational or seasonal activity. The survey will consist of core survey questions with additional information collected as needed by geographic region. GPS data will be collected where feasible.
