Nohyeong Jeongjon Public Parking Building

This four-level parking building already used an overhead ultrasonic guidance system on floors one to three, but its rooftop spaces were not included in the availability displays.

Woojoo Sensor was installed in 48 rooftop spaces and connected to the existing guidance system, enabling displays to show availability across all floors. Drivers can also check congestion and available spaces through the Woojoocha app before or during their trip.
