A vehicle parking system that helps drivers find a vacant spot. Using sensors in each parking space that detect the presence or absence of a vehicle, signs direct incoming drivers to available locations. For example, in the early 2000s, a smart parking system was installed at the Baltimore-Washington International Airport. Prior to installation, the parking garages closed when they were about 90% filled. With the Smart Park system, the garages close only at 99% occupancy. See smart car, smart home and smart.
