Kirkland, Wash. -- San Francisco commuters on average wasted 48 hours in traffic last year, the third highest figure in the U.S., according to a new report from Inrix. Honolulu (58 hours) tops the list, followed by Los Angeles. All told, 70 of the nation's 100 most populated cities showed decreases in traffic congestion last year -- a trend Inrix attributes to a lack of employment combined with high fuel prices. The report also cited an 11-mile stretch of the CA-4 EB (California Delta Highway) from Bailey Rd. to Somersville Rd. as the country's 10th worst traffic corridor. The stretch takes 16 minutes on average to travel, with 11 minutes of delay.
