An elevator system , comprising: a destination entry device configured to allow a passenger to indicate an intended destination prior to entering an elevator car ; at least one detector , wherein the detector is configured to: detect a proximity between the passenger and at least one other individual that has not indicated an intended destination through the destination entry device ;and a controller configured to determine whether the detected proximity between the passenger and the at least one other individual satisfies at least one criterion indicating that the at least one other individual is likely associated with the passenger and will board an elevator car with the passenger and travel to the intended destination with the passenger, and assign an elevator car to carry the passenger and the at least one other individual to the intended destination when the detected proximity satisfies the at least one criterion; characterized in that : the detector is configured to provide an indication of a first zone in which the passenger is located; and provide an indication of a second zone in which the at least one other individual is located; and the controller is configured to determine whether a relationship between the first zone and the second zone satisfies the at least one criterion. a destination entry device configured to allow a passenger to indicate an intended destination prior to entering an elevator car ; at least one detector , wherein the detector is configured to: detect a proximity between the passenger and at least one other individual that has not indicated an intended destination through the destination entry device ;and a controller configured to determine whether the detected proximity between the passenger and the at least one other individual satisfies at least one criterion indicating that the at least one other individual is likely associated with the passenger and will board an elevator car with the passenger and travel to the intended destination with the passenger, and assign an elevator car to carry the passenger and the at least one other individual to the intended destination when the detected proximity satisfies the at least one criterion; characterized in that : the detector is configured to provide an indication of a first zone in which the passenger is located; and provide an indication of a second zone in which the at least one other individual is located; and the controller is configured to determine whether a relationship between the first zone and the second zone satisfies the at least one criterion. determine whether the detected proximity between the passenger and the at least one other individual satisfies at least one criterion indicating that the at least one other individual is likely associated with the passenger and will board an elevator car with the passenger and travel to the intended destination with the passenger, and assign an elevator car to carry the passenger and the at least one other individual to the intended destination when the detected proximity satisfies the at least one criterion; characterized in that : the detector is configured to provide an indication of a first zone in which the passenger is located; and provide an indication of a second zone in which the at least one other individual is located; and the controller is configured to determine whether a relationship between the first zone and the second zone satisfies the at least one criterion. the detector is configured to provide an indication of a first zone in which the passenger is located; and provide an indication of a second zone in which the at least one other individual is located; and the controller is configured to determine whether a relationship between the first zone and the second zone satisfies the at least one criterion. <EOS>
