VDOT Bidirectional Traffic Volume 2024

This layer consists of Average Daily Traffic (ADT) volumes with Vehicle Classification Data for most recent years, on Interstate, Arterial and Primary Routes. It also includes a list of each Interstate and Primary highway segment with the estimated Annual Average Week Day Traffic (AAWDT) for that segment. It includes data from 1986 through 2024. Please note that traffic volume data here are bidirectional volume. The latest directional and bidirectional traffic volume data are also available in TMPD’s Pathways for Planning (P4P), https://vdotp4p.com.
