Importance of Roadway Condition 

1.Increase the efficiency and life of roads.

2.Reduces traffic congestion

3.Provide better means for development of

    infrastructures.

4.To find the need of improvement of a roadway or

    side walk or any other basic road component.

 5.To improvisation of pedestrian or vehicle

  movement or parking facility

Curbs

1. A curb the edge where a raised pavement/sidewalk /footpath, road median/central eservation, or roads shoulder/hard shoulder meets an unraised street or other roadway.

2. Curbs may fulfill several

functions.

3.Curbs can be used to channel runoff water from rain, or melted snow and ice into storm drains.

Shoulders

A hard shoulder, or simply

shoulder, is a reserved area

by the verge of a road or

motorway. Generally it is

kept clear of motor vehicle

traffic.

Super Elevation

Super elevation is tilting the

roadway to help offset centripetal

forces developed as the vehicle

goes around a curve. Along with

friction they are what keep a

vehicle from going off the road.

Link Road

A link road is a transport infrastructure road that links other major road transport facilities, often added because of increasing road

traffic. They can be controversial, especially if they threaten to destroy natural habitat and green field land 16

Side road

A side road or side roadway is a

narrow lane found in urban

areas, often for pedestrians only,

which usually run between or

behind the buildings…

Road Marking

Road marking is any kind of device or material

that is used on a road surface in order to

convey official information. They can also be

applied in other facilities used by vehicles to

mark parking spaces or designate areas for

other uses. Road surface markings are used on

paved roadways to provide guidance and

information to drivers and pedestrians.

Uniformity of the markings is an important

factor in minimizing confusion and uncertainty

about their meaning, and efforts exist to

standardize such markings across borders.

However, countries and areas categorize and

specify road surface markings in different

ways. Road surface markings are either

mechanical, non-mechanical, or temporary.
