Now a day the number of personal vehicles usage is increasing on a large scale. People prefer personal vehicles than public transportation. It is very difficult and frustrating as well to find parking space in most metropolitan areas, especially during the rush hours. It is often costly in almost every major city in the world to find proper and secure parking space. Due to this, there is a need to provide sufficient parking places providing plenty of slots to help the user park his vehicle safely. The aim of this paper is to propose a design of Android-based smart Parking System that regulates the number of cars to be parked in the designated parking area. This is done by automating the parking and unparking of the car with the help of an Android Application.
