Abstract: Worldwide, vehicles have become a very significant means of transport in which results into a huge number of cars that are owned in various cities, in turn traffic congestion and pollution leads. At top of all, parking has become the sparking factor of the mentioned problems. This paper puts an eye on various techniques as far as the smart parking system (SPS) is concerned which are already implemented. In looking after this parking issue, big number of authors contributed a lot in monitoring SPS and management of SPS with the help of various technologies including wireless sensor network, Bluetooth, Zigbee, RFID, GSM, Cameras, Image processing, IoT accompanied by a number of software solutions based on mobile application. Following this survey will enhance researcher’s thought on SPS which will result in a real solution of the technique and algorithms for ultimate SPS.
