    Mileage-Fee Design Strategies to Reduce System Cost and Increase Public Acceptance

    As traditional transportation revenue sources primarily based on gas tax continue to dwindle or stay even at best, the notion of transitioning to a vehicle-miles-traveled fee or mileage-based user fee has come under substantial consideration. Some design strategies can reduce system costs and increase public acceptance of mileage-based fees.

    America's Great Yellow School Buses

    One of the things taken for granted in the United States is the vast network of school buses—about 26 million children ride 480,000 buses every day.

    Paying for Infrastructure, a Taxing Issue

    If the “user pays” idea is worth saving, the United States needs a different calculation, writes Liisa Ecola. Some states are looking at mileage fees. With mileage fees, you pay based on the number of miles you drive, rather than the number of gallons of gas used.

    Modelling Long-Distance Travel in Great Britain

    Trips longer than 50 mi account for less than one-fortieth of all trips but nearly one-third of all distance traveled within Great Britain. Because of the small proportion of all travel that they form, long-distance trips may not be adequately represented in national databases and models.
