Features

Parking session correction is the most important functionality of Parking Session Logging API 2.0. The wireless data reception is not perfect, so some messages may be lost. To minimize this effect, Nwave recommends to use at least 2 stations in the same area, but message loss is still possible. Nwave Cloud analyzes additional data from parking sensors and recovers most of the lost messages. When a message is recovered, the Nwave Cloud analyzes occupancy history and makes a correction. It may correct the session’s start or end time as well as create new parking sessions.

Another feature is the addition of error start and end time. When 2 consecutive messages are lost, the Cloud cannot make a high-quality session correction, but to minimize negative effect Nwave has added delta_time_sec field. This field represents the maximum deviation in seconds from event time. This way, our API users can have information about sessions that are definitely correct and sessions that possibly had a time error and the duration of that error. This is useful in systems which generate data for parking enforcement applications - an inspector can be directed only to parking lots where cars are parked too long.
