23 54,18 ABSTRACT OF THE INVENTION A method of assigning hall calls to a plurality of elevator cars in an ETA strategy in which up hall calls are scanned upwardly and down calls downwardly. A hall call floor at which the scan has stopped for the purpose of assigning or reassigning a hall call at the floor is called a "scan floor". The floor of the advanced position of the car being considered for assignment is called the "AVP floor". In order to favor the clustering of closely adjacent stops in a given car, and thus minimize car bunching, when a car has an intervening stop between the AVP floor and the scan floor, either the travel distance between the AVP floor and the scan floor, or the travel distance from an intervening stop to the scan floor, is used to develop a dynamic bias for the ETA of the associat- ed car. The dynamic or variable bias is inversely propor- tional to the travel distance, i.e., the number of floors, between the relevant floors.
