An elevator control system to govern elevator movement to avoid or minimize passenger discomfort caused by pressure changes associated with an elevator's movement and to optimize elevator operation. In one exemplary embodiment, the system uses the passenger's natural relief which occurs while the elevator car is stopped to reduce the pressure difference experienced by the passengers' ears as a factor to optimally control the operation of the elevator. In another example, the system obtains input regarding the traveling speed and conditions of the elevator system. This system then simulates individual trips for passengers that includes monitoring the pressure changes being experienced by passengers throughout the elevator's travels in order to ensure that the pressure differential level for each passenger remains below a designated maximum comfortable and safe level. This system uses the parameters of a successful simulation to govern the actual operation of the elevators. 1.
