Monthly Vehicle Miles Traveled (VMT) is an essential metric in transportation planning, used to assess the total distance vehicles travel within a given region or network over the course of a month. This data provides insights into traffic patterns, road usage, and environmental impacts. Regular analysis of VMT helps identify trends, allocate resources, and improve infrastructure.

Monthly VMT plays a crucial role in shaping policy decisions regarding transportation efficiency and sustainability.

Various factors influence VMT, including:

  • Population growth
  • Fuel prices
  • Seasonal weather conditions
  • Economic activity and commuting patterns

To analyze and compare VMT data, transportation planners often use a combination of methods such as:

  1. Surveys and traffic counts
  2. GPS data collection
  3. Predictive modeling
