Now, congestion is a seriouscity disease of medium/large cities in China, which makes some streets of cities become "Parking Sites" at given time, and even it's considered as an "Intestinal Obstruction" for urban traffic.
According to "China Smart Parking Report" issued by ARI in 2016,the average GAP ratio of parking spaces in Beijing, Shanghai, Guangzhou and Shenzhen is up to 76.3%, at least 2 million cars in each city have no formal parking spaces, especially in some old residential districts, the insufficiency of parking spaces has brought a lot of trouble to car owners in these districts.
In fact, the traffic development of cities has been obstructed due to explosive increase of motor vehicles or continual acceleration of traffic congestion.
So we urgently need more automated parking garages to solve the traffic congestion in our cities.
