ratio scale

scale of measurement of data, having a fixed zero value, which permits the comparison of differences of values
NOTE: Ratio scaled parameters are applicable in mathematical equations using the operators multiplication and division.

relative charging error (RCE)

ratio between the absolute charging error and the reference value
NOTE 1 to entry: The topic of reference values (actual values) and how to handle them will be dealt with in the examination framework.

relative time

point in time relative to a defined event e.g. the entrance of a vehicle into an EFC specific area in minutes and/or hours

representative trip

trips that are of a distance larger than a defined threshold and so have to be considered by the related metrics
NOTE 1: Only trips which exceed the threshold and cover the specific types of roads of the Toll Regime have to be considered.
NOTE 2: The threshold may be defined as zero.

Satellite-based Toll System

An electronic toll system that uses a satellite navigation system (GNSS) to determine the position of a vehicle on toll road and a mobile data network to communicate with the central system. This approach eliminates the need for special roadside equipment (RSE), such as toll gates. The payment may also be defined using more complex rules (e.g., charges based on entry, time or distance) and can be…
