This data is part of the SANDAG Commercial Vehicle Survey 2022. It shows the proportion of trips by origin-destination segment and vehicle type.

Trips with neither trip end inside the region are labeled “external to region". Although sampled establishments included only those with business locations inside the San Diego region, the survey recorded stops made outside the region by the vehicles that those establishments operate. In such cases, external-to-region trips may not involve any travel that is within the San Diego region. For all vehicle types, most trips are internal to internal, accounting for 98% of trips made by light and medium vehicles and 90% of trips made by heavy trucks. All other light- and medium-vehicle origin-destination segments account for only 1 to 2% of all trips, while less than 5% of heavy-truck trips are either external-internal or internal-external, and the remaining 5% are external to the region.
