Grade Category


Grade Category identifies a change in slope based on driver perception.


Grade Category can be used to identify multiple levels of roads that may be present at a single place. For example, multiple flyovers, one over the other. Grade Category may be used to differentiate between ramps connecting to flyovers at different levels.


Grade Category is applied only for specific countries. Refer to the Country Specific Rules document for more information.
