The morning drive southbound on I-880 from San Leandro to Milpitas kept it’s number two ranking on the list from last year, second only to the westbound morning commute along Interstate 80 from Hercules to Oakland.
The commission defines “congested delay” as time spent in traffic moving at speeds of 35 miles per hour or less; the average delay per commuter has been steadily ticking up since 2010.
“A few things really stand out when you look at the data,” explained Santa Clara County Supervisor and MTC Chair Dave Cortese. “One is that congestion is concentrated in a select few corridors, primarily on routes leading into or out of Silicon Valley and San Francisco. Another is that over three-quarters of the congested delay is found on freeways in Alameda, Santa Clara and Contra Costa counties.”
The data comes from the commission’s Vital Signs performance-monitoring initiative.
