New Developments in Elevator Traffic Analysis

In this paper, certain algorithms in elevator traffic analysis have been verified by site measurements and improvements have been made. Beebe, in 1980, proposed several measuring parameters to identify the occurrence of up-peak and down-peak conditions. Site measurements in Hong Kong have been carried out to test the validity and usefulness of these parameters. Regarding improvements to existing algorithms, studies into the inverse S-P estimation and bunching factors of different orders for traffic status identification introduced by Al-Sharif were made. In this paper, a few suggestions have been proposed for improving the two methods to make them more practical in real applications at least in the Hong Kong environment and hopefully, applicable in other places throughout the world.
