Devices charge fees based on road use

Engineers at Oregon State University are working on a pair of devices that measure the number of miles driven between pit stops, then factor in a mileage-based fee at the gas station. State and federal officials hope that the system, which combines wireless Global Positioning System and odometer technology with shortwave radios, will transform how states tax road use.

As gas prices rise, many consumers are turning to more fuel-efficient cars and gas-electric hybrids to cut costs. That means states are losing valuable road revenue, said James Whitty, a manager at the Oregon Department of Transportation.
A mileage-based tax would ensure that those drivers pay for road maintenance, he said, ultimately replacing the fuel tax. Oregon's fuel tax provides 68 percent of the revenue of the state highway fund, which pays for road maintenance and construction, Whitty said.
The first device, located on the vehicle, monitors how many miles the driver travels before refueling. One version acts like an odometer. The other version relies on GPS satellites to pinpoint the vehicle's location within a certain zone – whether it's downtown or on the highway. At the gas station, the vehicle's device sends a shortwave radio transmission to a device on the pump. The device tallies the per-mile tax and adds it to the price of gas, replacing a fuel tax.

There are provisions to vary the rate based on the location or the time of day, such as evening rush hour on crowded roadways, said David Porter, the other Oregon State professor heading the project... California and Washington have expressed interest in the program, Cox said. And officials from 15 states recently met at the University of Minnesota to discuss the research.
