Real-time Parking Availability (RTA) RabbitMQ Occupancy API is capable of sending updates about parking occupancy with its a calculated summary. RabbitMQ Occupancy is also referred to as RTA (Real-Time Availability).

When you use this API, you are getting full occupancy info about parking. Nwave cloud calculates the number of occupied and vacant spaces according to parking type, parking sensors health and other secondary data.
