Even if some of the money comes out of their own pockets, most Americans believe the federal government should invest more than it currently does on roads, bridges and mass transit, according to a new AAA survey.

Two-thirds of survey respondents supported an increase in transportation funding, while more than half (52 percent) said they would be willing to pay higher fuel taxes if it meant smoother rides.

On average, AAA said, U.S. drivers contribute about $8 a month in federal fuel taxes. Twenty-one percent of Americans said they would add $10 or more to that monthly tab to fix the nation's aging infrastructure.

"I think particularly after this last winter, people are seeing what has happened to our roadways," said Cathleen Lewis of AAA New Jersey. "They're seeing more potholes, they're seeing more delays, and there's a real need for there to be a bigger investment."

A Rutgers-Eagleton poll earlier this year showed similar support for an increased tax at the pump.

A federal gas tax increase has strong support from AAA, which is calling on Congress for action. The federal pot for transportation money is expected to run dry without help from legislators.

Lewis said an increase in fuel taxes would result in a lesser expense for drivers than they currently put out for vehicle repairs due to deteriorated roads.

Democratic lawmakers in New Jersey have constantly pushed for a hike, but the proposal lacks support from the governor.
