Lane load on a road is described as which type of load in structural terms?

• A. Point Load
• B. Uniform Load
• C. Uniformly distributed Load
• D. Concentrated Load

Answer: (C)

Lane load represents the weight of traffic spread across the wheel track, not concentrated at a single point. In structural terms, this load is modeled as a constant intensity along the length of the lane, since vehicles continuously place pressure over an extended contact area and along a length of pavement. That is why it is described as a uniformly distributed load (a constant load per unit length, often treated as a line load w per meter). Treating it as a point or concentrated load would exaggerate local effects and not reflect how traffic weight is actually carried by the lane.
