Statewide Traffic Volume Historic and Forecast Historic traffic volume observations, future traffic volume forecasts, and adjustment factors -- are summarized using Utah's roadway planning summary segments -- for the Wasatch Front Regional Council metropolitan planning organization travel model area. This dataset can be viewed in an interactive map at: https://wfrc.org/traffic-volume-map/. This dataset provides segment level traffic volume data (historic estimates and future forecasts) within the state of Utah. Wasatch Front Regional Council (WFRC) metropolitan planning organization's travel model boundaries (including Salt Lake, Davis, western Weber, and southern Box Elder counties' urbanized areas). Future forecasts have been developed with the support of the Wasatch Front Travel Demand Model (v8.3.1) in conjunction with the adopted 2019 Regional Transportation Plan (RTP). This dataset was first released May 5th, 2020 (check the RELEASE field/column attribute for most recent update date). MAG travel model boundaries include the urbanized areas of Utah County. Cache travel model boundaries include Cache County. Dixie travel model boundaries include Washington County. Also contained within this dataset are adjustment factors, developed as part of a statewide effort led by UDOT, that can be used to scale the Average Annual Daily Traffic (AADT) volumes estimates and forecasts to provide more time-period specific volumes for a time period subsets (e.g. weekdays, weekends, specific months, seasons, maximum month, etc).
