    Significance of Traffic Volume Studies

    • Necessary for highway planning, design, and traffic control
    • Helps determine the capacity of roads and intersections
    • Provides data for traffic signal timing

    Intersection Differences

    • At-Grade: Intersections where roads cross at the same level
    • Grade Separated: Intersections where roads cross at different levels, usually with overpasses or underpasses

    Camber

    • Transverse slope provided to the road surface
    • Helps drain rainwater and prevent ponding
    • Ensures better stability and traction for vehicles

    Super Elevation

    • A banking of curves on roads to counteract centrifugal force
    • Reduces the tendency of vehicles to skid outwards while navigating a curve
    • Improves vehicle safety and comfort

    Station Yards

    • Railroad areas specifically designated for train operations like arrival, departure, and shunting
    • Types: Marshalling yards, classification yards, passenger yards, goods yards
