Annual Vehicle Miles of Travel (VMT)

Montana's Estimated Monthly Vehicle Miles of Travel (MVMT)

This report shows Montana's urban, rural and statewide estimated monthly vehicle miles of travel. Montana's estimated MVMT is generated by FHWA using traffic and roadway data from the Highway Performance Monitoring System (HPMS) and monthly traffic data supplied by TDCA. The monthly traffic data is collected from the permanent counters (ATRs and WIMs) located on public roadways across the state.

Nationwide Estimated Monthly Vehicle Miles of Travel (MVMT)

Traffic Volume Trends is a monthly report based on hourly traffic count data reported by the States. These data are collected at approximately 4,000 continuous traffic counting locations nationwide and are used to estimate the percent change in traffic for the current month compared with the same month in the previous year. Estimates are re-adjusted annually to match the vehicle miles of travel from the Highway Performance Monitoring System and are continually updated with additional data.

Annual Traffic By Sections (TBS) Reports

Traffic By Sections – On System routes only - The new Traffic By Sections (TBS) report displays three years of traffic data using MDT's Departmental Route naming protocol (I-90, N-1, P-9, etc.). Referencing and description information, the Annual Average Daily Traffic (AADT) and the Daily Vehicle Miles of Travel (DVMT) for all vehicles (Types 1-13) is reported for each roadway segment. Commercial truck information is provided where available.

The report contains the historical traffic data available for each permanent count site.

Monthly ATR and WIM Reports

The Monthly Comparison reports provide the change in traffic volumes, as compared to the same month last year (i.e. January 2016 as compared to January 2015), at each of MDT's permanent traffic counter locations.

Vehicle Classification Schematics:

The Monthly Calendar provides traffic volumes by day, by direction and by roadway from MDT's permanent traffic counters.

These reports provide a general overview of the monthly traffic trends at each of Montana's permanent counter locations but the trends are not necessarily representative of the statewide trend.
