Examples
A scale or examples should be provided: what is a poor, average, high pphpd, regarding cities, hours, type of transport mode chosen, capacity, etc. — Preceding unsigned comment added by 89.211.37.178 (talk) 11:02, 27 May 2012 (UTC)

Lowercase
This is generally used lowercase (pphpd) rather than uppercase. —Sladen (talk) 16:19, 10 July 2008 (UTC)

British escalator configuration
The caption for the image mentions a choice between (↑↑↓ or ↑↓↓). I think such a bank of escalators in the United States would more likely offer a choice between (↓↑↑ or ↓↓↑) since pedestrian traffic tends to follow a "walk on the right" rule adopted from the "drive on right" rule applied to motor traffic. 69.119.27.73 (talk) 14:41, 20 June 2009 (UTC)
