Speed-dependent capacity of an escalator for different values of the time gap <i>T</i>.

The diagram compares Eq (16) for different T-values with maximum observed flows summarized in Table 1 and ‘practical’ capacities provided by manufacturers [3–5]. The escalator parameters are fixed by dstep = 0.4 m and w = 1 m . By definition, the capacity should be as big as or larger than observed flows.
