Entry signs guide the driver to the actual parking area and the number of available spaces in each area or level can be displayed along the route. Highly visible green or red light indicators above each parking spot show the occupancy or availability of the space. While customers can easily locate available parking spot without painstaking searching, there is also less traffic and idling during parking. A good thing for the environment as well! When the customer leaves the parked car, a welcoming audio message or a commercial will be played automatically on each individual indicator. This unique feature creates an excellent opportunity for advertising and reaching customers, even with customized messages.
