Technical Data

2035 Highway Future Volume Table

The 2035 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. For information on how to use this table, see Section 5.5 of the Analysis Procedures Manual.

Note: 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.

Automatic Traffic Recorder (ATR) Characteristic Table and Map

The Automatic Traffic Recorder (ATR) Characteristic Table (XLS) can be used to estimate seasonal traffic count adjustments. For information on how to use this table, see Section 5.4.2 of the Analysis Procedures Manual (APM).

The ATR Characteristic Map is web based mapping tool that displays ATR’s based on their characteristic trend. Detailed information can be displayed on the map by clicking on ATR symbols. The ATR Characteristic Table and map are updated on a yearly basis, typically in September.
