PARKING OCCUPANCY DETECTION USING IOT

one of the major challenges faced by busy cities is traffic congestion. Parking vehicles in a traffic dense environment is time consuming and fuel wastage, the driver may loss time by driving in search for free space which ends up in congestion and increases the environmental pollution. Lack of information of vacant parking spaces is one reason for inefficient parking behavior. Smart parking sensors and machinery facilitate guidance of drivers to free parking spaces thereby improving parking order. Currently, no such sensors or technologies are in use for open parking lot. Ultrasonic sensors and machine vision were few of the extensively used sensors and technologies on closed parking lots. As the number of vehicles keeps on increasing an efficient parking system must be implemented. As a solution this paper aims to set up a Smart Parking System by using technologies like Internet of Things. This system helps to find the parking slots with real-time data being stored in cloud, we also build an android application which shows all the details of the parking lots in the city and free spaces present there. Using this application the user can prebook a parking space in their desired location if there is empty parking space available. This reduces time loss in search for parking space and also decreases the air pollution. Also another main feature of this application is that people with large space can register their place in it, which can be used as parking ground using our technology. This will be very helpful in times of sudden demand for parking spaces the nearby people can register their grounds to our application and the people visiting can park their vehicles in the spaces available.
