SAN FRANCISCO -- Any Bay Area motorist who has brought their vehicle into a repair shop won't be shocked by the finding of a national study of roadway conditions released Wednesday. San Francisco, Oakland and San Jose roads inflict some of the most expensive damage to fix in the country.

TRIP, a national transportation research group, found that poor road conditions end up costing motorists $413 annually in additional vehicle operating costs due to accelerated vehicle deterioration, additional maintenance needs and increased fuel consumption.

But the $413 is a bargain to Bay Area drivers.

The 10 urban regions with at least 500,000 people where motorists pay the most annually in additional vehicle maintenance because of road condition were -- Los Angeles, $778; San Francisco-Oakland, $761; Honolulu, $760; San Jose, $746; San Diego, $684; Tulsa, $682; Oklahoma City, $661; Sacramento, $655; and New Orleans, $636.

Going hand-in-hand with those findings was the poor conditions found on local roads.

The Trip survey found that the 10 largest urban regions with the greatest share of major roads and highways with pavements in poor condition were -- Los Angeles, 65%; San Francisco-Oakland, 62%; Honolulu, 62%; San Jose, 60%; San Diego, 53%; New Orleans, 50%; New York City, 49%; Sacramento, 46%; Baltimore, 42%; and Oklahoma City.

"With state and federal transportation funding falling short, the cost of materials and repairs rising and traffic volumes increasing, transportation agencies will face a significant challenge in improving urban pavement conditions," said William M. Wilkins, TRIP's executive director. "The nation needs to develop a new long-term vision for its highway system that would include improving conditions and safety and reducing traffic congestion."

According to the TRIP report, continued increase in urban traffic was putting significant wear and tear on the nation's roads. Overall travel on urban roads increased by 39 percent from 1990 to 2005; urban travel by large commercial trucks grew at an even faster rate, increasing by 49 percent from 1990 to 2005.

Large trucks place significant stress on road surfaces. Overall vehicle travel was expected to increase by approximately 30 percent by 2020 and the level of heavy truck travel nationally is projected to increase by approximately 39 percent by 2020.

Although the share of major urban roads in poor condition has decreased since 2002, conditions were likely to worsen -- survey officials said -- in the future under current transportation funding projections.
