McCain's parking guidance solution is a combination of intelligent software and hardware that easily guides drivers to closest available parking structure and space. The system utilizes variable message signs strategically located along the roadside and freeways, parking guidance signs located at the entrance of the parking structure, aisle boards located on the levels, and LED bay sensors located in each parking stall. With this system installed parking structures are able to utilize every space in their structure through single space detection and accurate space counting. Utilizing every space in your parking facility is equivalent to adding a brand-new level to your parking structure.
