Refer to the exhibit (graph of moving walkway speed vs.

The graph plots moving walkway speeds (feet per minute) on the horizontal axis against the nominal number of passengers per hour on the vertical axis. The curve labeled “Single Lane (90 cm tread width)” shows the passenger capacity for different speeds of a single moving walkway lane.

For a nominal passenger flow of 4,500 passengers per hour on a single lane, trace horizontally from 4,500 on the vertical axis to intersect the single lane curve.

The intersection corresponds approximately to a speed of 150 feet per minute (fpm).

Speeds lower than 150 fpm (e.g., 110 or 130 fpm) correspond to lower passenger capacities (below 4,500), while 170 fpm exceeds 4,500 capacity.

This data is important for architects and planners to size and specify moving walkways in transit terminals, airports, or large public buildings to maintain efficient flow and minimize congestion.

According to NCARB’s ARE Project Planning & Design guidelines, understanding capacity and circulation rates for building systems such as moving walkways is essential for designing efficient pedestrian movement and circulation within complex buildings.
