SMART CAR PARKING SYSTEM USING GRAPH ALGORITHM

Abstract

An effective car parking of a condo is conducted in this system with the aim of reducing the time for finding the free parking lots. The condo has an two-way road for each entrance and exit. Smart car parking enables the user to find the nearest parking areas. Push Buttons are used for validation when the user arrives the entrance. If the user presses to Push Button, the system will check for the nearest empty slot and show the user in LCD and the gate is opened by using servo motor. Graph Theory is applied to find the shortest path. As soon as a car has left from a slot, this system redefines the state of the slot as free. This system is implemented by using Arduino mega 2560 microcontroller, Push Button, LCD display, Ultrasonic sensor and Servo Motor. This system is implemented using C++ programming language with Arduino software IDE (Integrated Development Environment).
