Weekly Traffic Volume Report
The Traffic Volume report estimates the vehicle miles traveled (VMT) for interstate highways and how the total travel measured by VMT compares with travel that occurred in the same week of the previous year. The VMT is further split into passenger vehicle and truck components. The information gives new insights into the effect on traffic by storm activity, economic fluctuations, and other variables that could not be evaluated using the monthly report.
The Office of Highway Policy Information serves as the national source of surface transportation data; providing the U.S. DOT, Congress, and transportation community with accurate information products in a timely manner to inform the development and implementation of decisions, policies, legislation, programs, and performance goals, while constantly striving to improve the efficiency and effectiveness of data collection and analysis on travelers and the physical, operational and financial condition of our transportation system.
