VANET Based Embedded Traffic Control System

Globally traffic congestion is considered to be an important issue, which can be reduced by proper traffic monitoring system. More recently, the advancement in wireless sensor technology shows a great promise in designing intelligent transport system due to its flexibility and cost-effectiveness for deployment. This paper proposes a prototype vehicle traffic monitoring system using piezo based density calculation and RFID wireless technology for smart control. In conventional system traffic lights are designed on fixed time basis. The main objective of the proposed system is to operate the traffic light on instantaneous traffic density or have an adaptive traffic signal. The piezo sensors continuously senses the pressure of the vehicle and sends output voltage to the microcontroller which determines the length of time the signal must be given as green signal. Vehicular ad-hoc network is the best technology to improve the traffic security, proficiency and to enable various other related applications in the domain of vehicular communication. Applications using vehicular ad-hoc networks have diverse properties. Applications such as clearance to emergency vehicles (Ambulance, Fire truck), Vehicle-to-Vehicle communication plays a major rule in properly manage traffic situations. In this proposed system RFID reader detects the RFID tag of given to special vehicles allowing those vehicles to gain first priority. These applications are the classic models of an intelligent traffic control system which aims to enhance security and efficiency in traffic management using new technology for measuring instantaneous traffic and vehicle to internet communication to provide smart control.
