The parking addressing and guidance system aims to guide the user to the nearest free stall and, in the shortest possible time; in order to reduce waiting times, parasitic traffic and increase safety inside the parking lot. The parking guide system provides for the installation of a series of detectors (cameras, ultrasonic sensors, magnetic sensors or optical sensors) with relative indicators and / or Led displays positioned so as to instantly check the occupational status of the single stall or larger areas of the car park.The electronic control units, connected with the detectors, acquire the employment situation of the individual parking areas by sending the data to the display, signal and any management software installed on the server. Led displays and signal lights allow users to be directed quickly to the parking area with free parking spaces; the software allows the car park manager to acquire important information relating for example to: rotation of the stalls, occupational levels, time spent in the car park, most used areas.
