Classification of Roads and Highways 1Road Classification

Orderly grouping of roads into systems according to the type and degree of service they provide to the public2PurposeThere are different types of roads. Each of which performs a particular service in facilitating vehicular travel between points of trip origin and destinationTo guide future decision about the operation, maintenance, planning and development of the networkTo guide expectations about the level of service that might be experienced by those who will use or interact whith the facility. To ensure funds are spent on proper roads3Factors Affecting ClassificationBasis of these classifications are : 1 legal control2 surface type3 Function4 Geometric Elements5 Location6 Traffic Volume4Design Classification SystemThese system separates the roads; on the basis of difference in traffic service and land service.

However, it is significant for classification only in determining the number of lanes and whether roads should be divided or undivided Design Classification System143.
