"Researchers at the Texas Transportation Institute found that motorists in Los Angeles and Orange counties wasted an average of 72 hours in rush-hour traffic in 2005. That's one day shy of two full work weeks a year and 20 hours more than in 1985."

"In Riverside and San Bernardino counties, drivers wasted an average of 49 hours stuck in peak-period congestion during 2005. But the increase in delays since 1985 -- a stunning 40 extra hours -- is twice what Los Angeles motorists experienced."

"The average annual delay in the Oxnard-Ventura area at rush hour was eight hours in 1985. It hit 39 hours in 2005, according to the institute, which is based at Texas A&M University."

"Nationally, the study shows that time wasted in rush-hour traffic has steadily risen from an average of 14 hours in 1982 -- the first year of the study -- to 38 hours in 2005."
