Currently, parking area constitutes nearly most of the traffic congestion is caused by vehicles searching around their destination and looking for a place to do parking. Due to this reason, many day-to-day activities are affected such as fuel wastage, time wastage, pollution, etc. These factors motivated us to build a new method for smart parking systems. [7] In this paper we have presented the Android based smart parking system based on how users are able to find parking slots online and reserve it. Also, in this system, users can reserve the parking slot in the specific zone, checking the free slots and reserving it as per the needs of the vehicle. Further the QR code is generated which encodes the unique details of the user. QR code is used for encryption and to ease the process of authentication. The Vehicle entering into or leaving the parking slot is controlled by an Android-based application. With various payment methods, users can make their transaction safely. The algorithm helps improve the probability of successful parking and minimizes the user waiting time. Thus, by using this system it becomes more convenient for users to make booking and park the vehicle in the peak hours.
