Question

In general, the outer edge is raised above the inner edge in horizontal curves for

Correct answer (B) Highways and Railways only Solution Super-elevation (or cant) is the inward transverse slope provided to the pavement or track to counteract the effect of centrifugal force in horizontal curves. 1. Highways : Super-elevation is a standard design requirement to ensure vehicle stability and passenger comfort at design speeds. 2. Railways : Super-elevation is provided to distribute the load equally on both rails and prevent derailment or excessive flange wear. 3. Taxiways : Aircraft move at very low speeds on taxiways. Providing super-elevation could cause issues for slow-moving or stationary aircraft, such as fuel imbalance or tipping. Therefore, taxiways are generally not super-elevated. Thus, the outer edge is raised above the inner edge for Highways and Railways only . The correct option is (B). Turn this into a strength.
