Road User Study Underway

The PPC National Evaluation of a Mileage-based Road User Charge, a federally-funded study, is evaluating the technical feasibility and public acceptance of a mileage-based charging system as a possible long-term replacement for the current motor fuel tax (gas tax). Participants have been recruited in six locations nationwide. The study involves temporary installation of an on-board computer in your vehicle to record charges due from road use. For the study, however, no actual usage fees will be collected. Participants will be compensated for their participation in the study.
