Rankings are for routes in which continuous stop-and-go conditions occur with few, if any, breaks in the queue. Thus, corridors that have equally severe delays but where congestion is broken into several segments may rank lower in this type of congestion listing. Similarly, the length of congested corridors in 2016 may be longer or shorter than those identi� ed in the 2015 report.

*2015 rankings have been updated to correct an error in data originally reported for the I-680/I-280 corridor in Santa Clara County.
