... 50 that they could support. The second set of criteria includes a broader range of issues that could also affect the desirability of the potential implementation options, including cost, functional considerations, administrative complexity, and user acceptance.

... 52 Reviewing the entries in Table 4.1, one can see that the GPS-based option provides the greatest flexibility. It is the only option capable of distinguishing applicable fees by route (for example, excluding the assessment of VMT fees for travel on private roads)
From page 54...
... 53 User acceptability • Burden on individual drivers • Burden on private sector • Ability to audit charges • Privacy concerns The previous NCHRP 20-24(69) study evaluated the different implementation options with respect to these criteria from the perspective of implementing a national system of VMT fees.
From page 55...
... 54 4.2.1. Pricing Capabilities The Commission recommended that VMT fees should be able to serve as a single mechanism to be used for all transportation taxation and pricing.
From page 56...
... 55 • Allow for (and eventually require) the metering equipment to be pre-installed with new vehicles and to be retrofitted for existing vehicles • Rely on federal technical standards that would govern the design of any metering equipment provided by states, localities, or private operators or firms 4.3.

... 56 equipment. That is, instead of developing separate AVI devices that were only capable of providing vehicle identification and/or fuel economy information, the trials could include more advanced OBUs (i.e., OBUs with GPS or with cellular location)
From page 58...
... 57 4.3.2. Payment Mechanisms The Commission's recommendations explicitly call for accommodating multiple forms of payment.
From page 59...
... 58 • External DSRC/ANPR checks • Device heartbeat signals • Device distress signals In the event that these could not be demonstrated as effective, in might prove necessary to rely on options that require a greater degree of manual intervention: • Odometer redundancy checks • Metering equipment inspections 4.3.4. Mechanisms for Protecting Privacy The NSTIFIC recommendations also stress the importance of providing strong privacy protection for motorists that desire such functionality.

... 59 consider, within the context of the trials, whether the various metering configurations examined in the trials could later be provided as standard equipment in new vehicles. • Voluntary Opt-In.
