Average Traffic Volumes - Local Jurisdictions

Periodically, local jurisdictions collect traffic count data on significant roadways. SANDAG compiles this information to present average weekday traffic counts, which are two-way, 24-hour volumes. The table below shows roadway descriptions and five-year (2009-2013) volumes.

Note: If counts were not made in a particular year, the previous year’s count will be shown along with an N. An E will appear by the volume if the traffic count was estimated. A V indicates that the street did not permit through traffic for that year. Additional counts may be available by contacting each jurisdiction's Public Works Department.

Average Traffic Volumes - Regional Freeways and State Highways

For traffic volumes on regional freeways and state highways, Caltrans offers two online resources. The Caltrans Traffic Census presents annual average daily traffic counts. Caltrans also maintains the Performance Measurement System, which is a more interactive tool to query and visualize a variety of highway information, including traffic volumes.

Vehicle Miles of Travel

The Caltrans Highway Performance Monitoring System and its data archives (1996-2000) are a statewide source for daily vehicle miles of travel (VMT) data. These tables list VMT for San Diego County by jurisdiction and roadway type.
