Work includes identification of data sources, analyzing those data for useful insights, and providing measures of congestion and vehicle travel. Examples of current work are:
Seasonal adjustment of monthly highway congestion data
Trending and seasonal adjustment of vehicle miles traveled
Improved estimates of freight ton-miles .
Rail freight performance measures
