On Traffic Planning Methodology

Measurements in office buildings show that passenger traffic intensity is often highest during the lunch hour period. Up-peak boosters are used to increase handling capacity during heavy incoming traffic. Boosters decrease round trip time and the number of stops elevators make. Control methods such as floor zoning, or guiding passengers with the same destination to the same cars are used. If up-peak boosters are used at the planning stage, handling capacity during the lunch hour period becomes critical. During mixed interfloor traffic pattern, efficient call allocation algorithms provide better service than up-peak boosters. This paper considers traffic planning methods and the capability of different control algorithms to handle lunch hour traffic.
