absolute charging error

difference between the measured charge (toll) value and the actual value as measured by a reference system where a positive error means that the measurement exceeds the actual value.

difference between the measured charge (toll) value and the actual value as measured by a reference system where a positive error means that the measurement exceeds the actual value.

accepted charging error interval

interval of the relative charging error that the toll charger considers as acceptable, i.e. as correct charging

interval scale parameters

scale of measurement of data, according to which the differences between values can be quantified in absolute but not relative terms and for which any zero is merely arbitrary
NOTE: Interval scaled parameters are applicable in mathematical equations using the operators plus or minus. Interval scales having a zero offset are equal to ratio scales.
EXAMPLE: The temperature scale in Celsius…

NOTE: Interval scaled parameters are applicable in mathematical equations using the operators plus or minus. Interval scales having a zero offset are equal to ratio scales.
EXAMPLE: The temperature scale in Celsius is an interval scale, in Kelvin it's a ratio scale.

nominal scale parameters

discrete classification of data, in which data are neither measured nor ordered but subjects are merely allocated to distinct categories
NOTE: Nominal scaled parameters are applicable in Boolean equations using the operators equal or not equal.
EXAMPLE: A nominal scale parameter for vehicles could consist of cars, trucks, vans and motorcycles.

ordinal scale parameters

scale on which data is shown simply in order of magnitude since there is no standard of measurement of differences
NOTE: Ordinal scaled parameters are applicable in Boolean equations using the operators greater, greater or equal, less or less or equal.
