Skip-Stops. Many schemes have been tried to reduce the number of stops an elevator will make, thereby attempting to improve operating efficiency and to reduce equipment costs. Each has disadvantages with respect to floor access and most are not legal where legislation for disabled persons has been enacted. The most notable are schemes involving skipped stops on either a single elevator or groups of elevators. 12a and b). The disadvantage is obvious: With the singleskip scheme, persons on the floor skipped must walk either up one floor or down two.
Knowing or estimating the number of stops provides a means to calculate the total time for functions and leads to the cycle time or round-trip time of a single elevator. The number of stops can be established by applying a statistical formula, by inspecting the various attractions of each floor at which an elevator is required to stop, or by a combination of statistical and logical determinations. The various approaches are discussed in Chapter 19, on evaluating elevator performance. On a single elevator or escalator, once the time required to serve a given number of people is determined, the number and size of elevators or escalators that will serve the critical pedestrian traffic can be established.
