are 3 main types of Parking Guidance Systems available in the market: indoor
standard, indoor spot control, and wireless. The first relies on ultrasonic
sensors to indicate the vacancy, the second is camera-based, and the third is
usually used in outdoor applications. In any case, there are 3 things any engineer
should consider when designing a parking guidance system.
Parking Space Usage
The first step is to determine the exact usage of the parking space with the client. If the client wishes to use the spaces to indicate vacancy only, then a 2-color system is sufficient. However, if he wishes to reserve places for handicapped people, VIPs, guests, or other residents than a 3-color system is preferred.
Choice of Sensors
Determine the number of sensors as per the parking
spaces available. Each parking space
should accommodate a sensor and an indicator. A combined sensor/indicator could
be a cheaper solution if the project is tight on budget. Also, make sure to
conduct a site survey to determine the mounting options available. This is
critical in determining the accessories needed before installation.
Type of Displays
Displays are a major part of the Parking Guidance System because they act as prime indicators for residents. The number and location of the displays depend on the natural flow of cars. Position the displays such that they indicate the number of available spaces in each segment. Finally, consider mounting a master display, sometimes called Totem display, at the parking entrance showing the empty parking spaces in all the floors.
