Passenger conveyors are used at locations where a large concentration of passengers has to be moved from one place to another. Escalators are used to convey passengers from one level to another. Examples of location of passenger conveyors are :
(a) Airport passenger terminals
(b) Metro rail
(c) Shopping Malls
The speed at which passengers are moved in passenger conveyors at one level is about 1.0-1.5 m/sec to make it comfortable. The speed of escalators is about 0.5-1.0 m/sec to make it comfortable for alighting and embarking passengers.
