Integrated Real-time Vehicle Speed Control System using RFID and GPS

In today's world as vehicles are increasing on the roads, reducing road accidents is a major concern. Neglecting the rules while driving is a major cause for accidents. In this scenario, this paper proposes a suitable method to reduce the road accidents to a great extend due to over speed. Unlike the existing methods, which controls the speed of the vehicle at a constant rate, this work proposes an integrated approach to effectively control the speed of the vehicle at varying rate based on the maximum permissible speed limit of the protected or restricted zones such as hospitals, schools and crowded areas. A passive RFID integrated with GPS locator in the vehicle provides a promising solution to control the speed of the vehicle based on the allowable speed limit of the particular location. A prototype resembling an electronically controlled road vehicle with customized speed limits is used for our work. RFID reader inside the vehicle captures the unique encoded signal from the RFID tag placed at the speed limit zone and automatically controls the speed of the vehicle, when the vehicle approaches the proximity of RFID tag. The work also simulates speed control through GPS data which overcomes the limitation of RFID, and also proposes a solution to enhance the security of RFID tags.
