Classification of Roads 

roads

Road road classification system groups a limited number of clearly defined types.
Road classification purposes

A road network consists of several types of paths, each of which performs a particular service to facilitate vehicular traffic between points of origin and destination of the trip, and in providing access to the property. Road Classification is the array of roads in the systems according to the type and level of service offered to the public.
Consideration of classification - Factors that influence the classification of roads

Many different classification systems have been introduced and used for a particular purpose. The basis for some of these classifications is:

      The legal control

      type of surface
      function
      geometric elements
      location
      Traffic volume

Rarely these classification system to differentiate between roads under a service that is essential for the designer of the road.
Design rating system

This system separates the roads;

      Based on the differences in service and traffic services land.

      Based on the geometric design features.

The eight main divisions of this system are:
rural

urban-local

local-collector

collector-arterial

arterial-freeway

freeway

1. rural and urban:

      Refers to the predominant feature of the use of the adjacent land and not only the jurisdiction boundaries or features of typical cross section.

2. Geometric Design:

      For purposes of geometric design is essential to divide each of these divisions. For a given road geometric design elements are affected by traffic volume. However, it is important for classification only in determining the number of lanes of the road and whether to split or divide.

3. Other variables

Are affecting geometric design;

      The type of road passes through the ground

      The financial resources available
      population density

          Developmental characteristics of the surrounding land, road and travel habits of the local population.

      Design speed is a measure of the quality and thus is the final sub division.
