About this dataset
This app provides the latest traffic volume data for every roadway in the Commonwealth. Traffic volumes are the most recent available and have been approximated in some cases. Click on any roadway to display the traffic volume information. Higher traffic volumes are not necessarily an indication of congestion. Real time mapping on www.511virginia.org provides indications of congestion. 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.
