A method of assigning hall calls to a plurality of elevator cars which biases the assignment process to balance the number of cars serving up and down service directions. Prior to each call assignment update the method determines the number of cars serving each service direction (78, 80, 82). A predetermined relationship (88) between these two numbers is used to determine if up hall calls should be assigned first, or down hall calls (90, 92, 94, 96). The balancing of cars serving the two service directions lowers the average waiting time, and it results in dispersing the cars throughout a building when service subsides, to enable prompt service for newly entered calls without the necessity of moving the cars during periods of low service to be in position for new calls.
