Abstract: A method of controlling a drive-thru operation of a quick-service restaurant (QSR) includes detecting using a range finding device, when a vehicle enters a drive-thru proximity zone of the QSR; measuring a plurality of range data of the vehicle entering the drive-thru proximity zone; transmitting simultaneously the plurality of range data to a controller device; calculating at the controller device, a dwell time of the vehicle based on the plurality of range data; determining at the controller device, whether the dwell time of the vehicle exceeds a pre-set dwell time threshold; transmitting the dwell time of the vehicle to a cloud server when a violation occurs; and instructing a central station from the cloud server to send a notification message to the QSR when the dwell time of the vehicle exceeds the pre-set threshold.
