A system for determining elevator car locations, the system comprising: a sensor, wherein the sensor is operated by a controller; and wherein the controller is configured to: determine that the elevator car is in motion based at least in part on the sensor; determine a direction of the elevator car while the elevator car is in motion based at least in part on the sensor; collect, from the sensor, sensor data associated with the elevator car while the elevator car is in motion, wherein the sensor data includes a travel time while the elevator car is in motion; access elevator car travel data from a travel time profile associated with the elevator car; compare the travel time to the elevator car travel data to determine a location of the elevator car in a hoistway; wherein the elevator car travel data comprises a plurality of origin-destination pair travel times for the elevator car in the hoistway, wherein the plurality of origin-destination pair travel times for the elevator car in the hoistway comprise: a first set of origin-destination pair travel times comprising actual travel times between a first set of floors serviced by the elevator car; and a second set of origin-destination pair travel times comprising calculated travel times between a second set of floors serviced by the elevator car, wherein the calculated travel times are based at least in part on the actual travel times, characterized in that the sensor is affixed to a moving component of the elevator system. a sensor, wherein the sensor is operated by a controller; and wherein the controller is configured to: determine that the elevator car is in motion based at least in part on the sensor; determine a direction of the elevator car while the elevator car is in motion based at least in part on the sensor; collect, from the sensor, sensor data associated with the elevator car while the elevator car is in motion, wherein the sensor data includes a travel time while the elevator car is in motion; access elevator car travel data from a travel time profile associated with the elevator car; compare the travel time to the elevator car travel data to determine a location of the elevator car in a hoistway; wherein the elevator car travel data comprises a plurality of origin-destination pair travel times for the elevator car in the hoistway, wherein the plurality of origin-destination pair travel times for the elevator car in the hoistway comprise: a first set of origin-destination pair travel times comprising actual travel times between a first set of floors serviced by the elevator car; and a second set of origin-destination pair travel times comprising calculated travel times between a second set of floors serviced by the elevator car, wherein the calculated travel times are based at least in part on the actual travel times, characterized in that the sensor is affixed to a moving component of the elevator system. determine that the elevator car is in motion based at least in part on the sensor; determine a direction of the elevator car while the elevator car is in motion based at least in part on the sensor; collect, from the sensor, sensor data associated with the elevator car while the elevator car is in motion, wherein the sensor data includes a travel time while the elevator car is in motion; access elevator car travel data from a travel time profile associated with the elevator car; compare the travel time to the elevator car travel data to determine a location of the elevator car in a hoistway; wherein the elevator car travel data comprises a plurality of origin-destination pair travel times for the elevator car in the hoistway, wherein the plurality of origin-destination pair travel times for the elevator car in the hoistway comprise: a first set of origin-destination pair travel times comprising actual travel times between a first set of floors serviced by the elevator car; and a second set of origin-destination pair travel times comprising calculated travel times between a second set of floors serviced by the elevator car, wherein the calculated travel times are based at least in part on the actual travel times, characterized in that the sensor is affixed to a moving component of the elevator system. a first set of origin-destination pair travel times comprising actual travel times between a first set of floors serviced by the elevator car; and a second set of origin-destination pair travel times comprising calculated travel times between a second set of floors serviced by the elevator car, wherein the calculated travel times are based at least in part on the actual travel times, characterized in that the sensor is affixed to a moving component of the elevator system.
