mbuf

Sounds like a good confab.

We've given too much publicity here to schemes for mileage-based user fees (MBUFs) or vehicle-miles traveled (VMT) charges. Those acronyms MBUFs or VMT fees are just proposals for comprehensive tolls - tolls on virtually all roads. We say we've given too much publicity to them, not because they aren't important, or don't make sense as substitutes for the old fuel taxes, but because they aren't going anywhere.

A group at the University of Minnesota (UMinn) says that fuel taxes are dysfunctional as the principal means of funding roads and recommends what they call 'mileage-based user fees' (MBUFs) or more simply nationwide tolls.

Skymeter's Bern Grush calls it TDP pricing - standing for charges that involve measures of Time, Distance, Place. Others call them vehicle-miles fees or mileage charges. Sometimes they become VMT charges for Vehicle Miles Traveled. Others again call them road user charges or road use charges, hence RUCs. Texas Transportation Institute scholars call them Mileage Based User Fees, MBUFs.
