Abstract: A vehicle presence detection system for determining whether a parking space is vacant or occupied and utilizing this information to guide vehicles to available parking spaces. generally includes a LIDAR device, a cloud-based processing unit, a database, and a guidance light. The LIDAR device generally includes a light emitter, a light sensor, a CPU, a memory unit, and a communications device. The LIDAR device determines the distance between itself and a parking spot or a vehicle parked in that parking spot using an algorithm that accounts for variances in the ambient conditions. This status information can be communicated to a cloud-based processing unit, which can store this information in a database and/or use this information to send parking status indications to an autonomous vehicle dynamic sign, mobile device, or guidance light.

Abstract: A vehicle flow monitoring system for detecting both a car count and direction of movement of vehicles passing a point of interest. The vehicle flow monitoring system generally includes a car counter which may include a microcontroller and a pair of distance sensors. Each of the distance sensors is oriented toward a unique point of interest. Each of the distance sensors includes a threshold distance reading which is used to detect whether a vehicle has passed underneath the car counter. The system may determine direction of travel of the vehicle based on which of the distance sensors is passed by the vehicle first. The microcontroller may assign an Event ID to each time a vehicle passes each of the sensors, with the Event ID being used to identify when and if the vehicle should be counted, or whether a non-vehicle object has passed the car counter.

Abstract: A vehicle presence detection system for effectively detecting the presence of a vehicle in a location based upon a measured radio wave signal strength by a receiver. The vehicle presence detection system generally includes a main receiver adapted for receiving a radio wave signal from a transmitter and a control unit in communication with the main receiver that determines a signal strength of the radio wave signal received by the main receiver. The control unit determines that a vehicle is near the transmitter or the main receiver when the signal strength of the radio wave signal is reduced by a threshold loss.
