VMT

This layers shows the traffic volume in an area measured by the annual vehicle miles traveled (AVMT) for HPMS segments in the Thrive Study Region. Data is from the Bureau of Transportation Statistics, and depicts the Federal Highway Administration's data that reflects the extent, use, condition, and performance of the public roads in the United States. Annual Vehicle miles traveled (AVMT) is a measure used in transportation planning for a variety of purposes. It measures the amount of travel for all vehicles in a roadway segment over one year period. AVMT is calculated by multiplying the average annual day traffic (AADT) by the length of the roadway segment. According to the Texas A&M's Transportation Policy Research Center, Vehicle Miles Traveled has many use cases, such as: Assess the differences in travel demand and impact between regions and other states. Project future revenue streams from fuel taxes and proposed VMT fees. Compare personal travel and freight/commercial vehicle travel. Project future congestion levels. Estimate the amount of travel resulting from local residence and freight activity versus external travel. Assess the impact of various population forecasts.
