Some solutions to this funding shortfall are as simple and straightforward as building on the progress made under TEA-21 to restore the "trust" in the Highway Trust Fund. First, every reasonable effort must be made to dedicate more user fees to roads and highways. The 18.3 cents per gallon federal gas tax deposited in the Highway Trust Fund has winnowed through the years; approximately 15.44 cents accumulates in the Highway Account, with the remainder distributed to the Mass Transit Account (2.86 cents). While this formula dedicates 15.6 percent of the revenue from highway users to the Mass Transit Account, billions more also are diverted from the Highway Account to transit under special programs promoted by groups that hope to force people to give up their cars, live close to work and do daily business and errands by bicycle or on foot. The classic case is the $1 billion a year Congestion Mitigation and Air Quality program, which cannot be used for highway-capacity projects and diverts more than half its funds to transit. This despite the fact that traffic-bottleneck removal, the surest means of reducing air pollution and congestion, is ineligible for funding. Since 1992, $14 billion has been spent on this program with little or no congestion or air-quality relief.
