We analyzed county-level Daily VMT (DVMT) data from 2019 to 2023, primarily sourced from the Highway Performance Monitoring System (HPMS). Our comprehensive approach relied on two primary methodologies: GIS-supported spatial analysis and advanced predictive modeling.
Vehicle miles traveled (VMT) is a fundamental metric for assessing mobility trends and infrastructure needs. This study examines the spatial-temporal
