Abstract
In response to a registered hall call, a car announcement is made when and only when an assigned car, of a plurality, has its RRT a calculated number of seconds lower than the car with the next lowest RRT to minimize actual waiting time wherein the calculation is performed as a function of the remaining response time of the assigned car, the waiting time of the passenger, and an RRT inflation factor which is an amount of deviation from the minimum expected remaining response time of the assigned car.
