Vehicle Kilometres Travelled (VKT) is a transportation metric measuring total distance driven by all vehicles within an area over a time period. VKT indicates transportation activity levels and relates to road wear, traffic congestion, fuel consumption, and transportation emissions. Transportation planners track VKT trends to understand travel patterns and evaluate policy effects. Reducing VKT per capita is often a goal for sustainability and congestion reduction—lower VKT may indicate successful transit investment, land use changes, or remote work adoption. VKT data comes from travel surveys, traffic counts, and fuel consumption estimates. The American equivalent metric, Vehicle Miles Traveled (VMT), measures the same concept in imperial units. VKT growth typically correlates with population and economic growth.
