LED Signs are designed to be the windows of the system, on which real-time parking availability information will be displayed. And there were two category of LED signs: outdoor and indoor.

 

Outdoor LED Sign is deployed at the entrance of the parking facility to display the total number of vacant spaces of the whole parking facility. Such LED signs, however, if installed on the totem on the main avenue, many parkers will be attracted to park.

 

Indoor LED Sign is strategically deployed at every decision-making point to tell driver to which direction to go or to avoid. Drivers simply follow the LED arrows and they will reach an empty space.
