Question

Traffic capacity is defined as:

• A. Ability of roadway to accommodate traffic volume in terms of vehicles per hour
• B. Number of vehicles occupying a unit length of roadway at a given instant expressed as vehicles per km
• C. Capacity of the lane to accommodate the vehicles width wise (across the road)
• D. Maximum attainable speed of the vehicles

Hint:

Remember: Capacity = maximum flow (vehicles/hour), Density = number of vehicles/km, Speed = distance/time.

Answer 1

The Correct Option is A

Phase 1: Traffic Capacity Assessment.
Traffic capacity refers to the maximum volume of vehicles that can traverse a specific point on a lane or roadway within a defined timeframe, given current conditions.

Phase 2: Evaluation of Alternatives.
- (A) Accurate: This aligns with the established definition of traffic capacity (vehicles per hour).
- (B) Inaccurate: This describes traffic density, not capacity.
- (C) Inaccurate: This pertains to physical dimensions, not capacity.
- (D) Inaccurate: This defines speed, not capacity.

Phase 3: Determination.
Therefore, option (A) accurately defines traffic capacity.
