Improved concept for derivation of velocity profiles for elevator systems

We concentrate on some important timing characteristics of elevator group control (EGC) systems. The main discussion and calculations should be considered as a further development of the three passages concept. To achieve better global performance of the EGC system, especially to reduce hall call waiting time, a calculation methodology of car kinematics is presented. The importance of detailed kinematics considerations is demonstrated with data taken from a real high-speed EGC system in 63-floor building in Seoul, Korea.
