Speed Categories

The speed category classifies the general speed trend of a road based on posted or legal speed and is provided to enhance route calculation and the timing of route guidance. Speed category values represent the combination of several factors besides legal speed limit (e.g., physical restrictions or access characteristics). Therefore speed category values can differ from speed limit values, which represent the legal speed limit only.
