At one of the world’s largest single-structure garages with 12,100 parking stalls, Seattle-Tacoma International Airport recently installed Park Assist’s Parking Guidance System to monitor occupancy and provide guidance throughout the enormous garage. Park Assist’s M4 smart-sensor system enhances the parking experience by indicating which specific spaces are available, occupied or premium using color-coded LED lights. The smart system streamlines parking and reduces congestion. Additionally, Park Assist’s Park Finder software module helps users quickly pinpoint their car upon returning to the garage.
