Super elevation is the banking of a road's outer edge to counteract the effects of centrifugal force on vehicles during turns.

• Super elevation is the tilt or slope provided to the outer edge of a road or track on a curve.

• It helps vehicles to navigate turns at higher speeds by counteracting the tendency to skid outwards.

• The amount of super elevation required depends on factors like design speed, curve radius, and friction between tires and road surface.

• Excessive super elevation...read more

Different types of junctions include T-junctions, Y-junctions, and cross-junctions.

• T-junctions: Three roads meet at a T-shaped intersection.

• Y-junctions: Three roads meet at a Y-shaped intersection.

• Cross-junctions: Four roads meet at a cross-shaped intersection.

CAD modeling involves creating digital representations of physical objects using specialized software.

• Start by creating a sketch of the part in 2D

• Extrude the sketch to create a 3D model

• Add details such as fillets, chamfers, and holes

• Check for any errors or interferences in the model

• Export the model in the desired file format
