Grade Separation and Interchanges
Grade separation is a method developed to avoid the disruption of traffic flow at intersections. Grade separation is adopted at junctions where two or more surface transport axes cross with each other. Different types of grade separation structures, advantages and ...
Curves in Alignment of Highways – Types of Curves
What is a Curve in Roads? A curve is nothing but an arc which connects two straight lines which are separated by some angle called deflection angle. This situation occurs where the alignment of a road way or rail way ...
