ABSTRACT:
An improved traffic demand analyzing system is disclosed in which the past traffic demand data that have occurred during the same predetermined unit time periods as the current time period are computed so that the past data may be implemented in the group control of the elevator operation. The system comprises a unit for measuring and storing the traffic volume for a plurality of predetermined time periods up to the current time period, and a unit for preestimating the traffic volume for the near future through placing greater emphasis on the traffic volume associated with said predetermined time period nearer to the current time or through making use of only traffic values associated with a certain number predetermined time periods near to the current time.
