42 • Accurate mileage counts. Given an intent to consider possible designs for a VMT-based system of road use charge, an ability to at least estimate mileage with reasonable accuracy must be presumed.

43 • Time of travel. Traffic congestion also varies by time, so this travel characteristic is also judged as a requirement for the policy goal of reducing congestion delays by charging higher per-mile fees for congested travel.

VMT-Fee System Evaluation Criteria Beyond the technical capabilities of a system for metering road use, which govern the feasibility of pursuing alternate policy goals, there are additional criteria that can be used to assess the relative merits of alternate VMT-fee implementation mechanisms intended to accomplish the same set of goals.
