Which term refers to the average rate of flow of people or vehicles through an access point?

• A. Flow rate
• B. Throughput
• C. Turnstile rate
• D. Occupancy rate

Answer: (B)

This question is about the rate at which people or vehicles pass through an access point over time. The term that captures this idea is throughput: the average number of units that pass through the point per unit of time, such as people per minute or vehicles per hour. Throughput reflects how efficiently the access point is moving people through, combining both the capacity of the point and the actual flow it handles. For example, if 180 people pass through in 6 minutes, the throughput is 30 people per minute. This metric is central to assessing performance and capacity of entry control points. Why the other terms don’t fit as precisely: flow rate is a related concept but can be ambiguous in everyday security contexts and isn’t the standard operational term used to describe how many units pass per time. Occupancy rate describes how full a space is at a given moment, not how quickly people are moving through the point. Turnstile rate is not a widely used, generic metric for overall access-point performance, and it focuses on a single device rather than the entire access point’s flow. Throughput specifically conveys the rate of passage through the point over time, which is what’s being asked.
