FABRICATION OF SECURED WIRELESS CONTROLLER FOR TRAFFIC SIGNALS AND REDUCING SPEED OF VEHICLE BY USING SENSORS

Abstract : This paper covers the design and implementation of an intelligent traffic management system for an isolated intersection. Vehicle Speed Detection is used to detect the speed of the running vehicle with the help of video and image processing techniques. We use camera to capture and analyzed the speed of the vehicle in real time. We detect the vehicle speed with the help of Arduino and IR sensor. Speeding is one of the major factor of all fatal motor vehicle crashes and accident. This system is designed to reduce the road accidents in the development of the vehicle speed detector system by using an IR sensor, Camera, 16x2LCD, buzzer, LED and Arduino UNO. In this system we don’t need any human work to record the vehicle speed and informs the nearest authorities about the driver and get punished for it. The vehicular traffic management system employs Field Programmable Gate Array (FPGA) as the central decision-making unit and combines its speed and high number of I/O with other system components such as the ESP8266 Wi-Fi module, to record real-time traffic information and apportion green time for each phase of traffic signal. The design and implementation incorporate three different operational modes namely, fixed time mode, sensor actuated mode and remote control mode, to alleviate vehicular traffic congestion and also reduce the risk of accidents at intersections. The incorporation of remote control mode, which enables an authorized personnel to remotely control the traffic, using a cloud-based application running on a portable device, makes this system different from previous works. Simulation using a prototype of the model on a model intersection, shows that the system can reduce waiting time and increase throughput at the intersections.

 EXISTING SYSTEM :

 • It is compatible with existed traffic signal controller so that it can be fast and cost-effectively deployed. • In the existing method there is a radar gun which works on the principle of Doppler effect. By calculating the speed and if the speed exceeds the limit then camera will be ON and takes the picture of vehicle and sends the image to the server computer. • In order to fast and cost-effectively deploy the STSC system, our idea is that the RSU controller has to be compatible with the existed infrastructure so that there is no need to replace the traditional traffic controllers. • However, some limitations exist for the use of intelligent traffic control, for example avoiding traffic jams is considered beneficial for both the environment and the economy, but improvement in traffic flow can lead to an increase in demand. • The major problem of the existing traffic light systems is that the transition timing slots are fixed within the code. • There are many models for traffic simulation in our research, we use the IR sensor to optimize the traffic light controller in the city and pay attention to the visual monitoring developed using the PIC microcontroller.

 DISADVANTAGE :

 • The problem of vehicular traffic congestion is one that accompanies development and urbanization in every country. • Urbanization is inevitable and hence its accompanying road traffic congestion problem, various ways must be devised to reduce the road traffic congestion as much as possible. • One attempt by government to handle the congestion problem is to construct more roads. • The work seeks to address two main problems, heavy traffic jams during peak hours and allocation of green-time to roads when there is no traffic on them using image processing based traffic light controller. • The ultimate research issues that researchers seek to address in the area of intelligent traffic control include, but not limited to, how to reduce traffic congestion; avoid crashes; automatically give right of way to emergency vehicles; provide road traffic information to users; allow remote control of traffic at intersections; and coordinate the traffic flow through adjacent intersections.

 PROPOSED SYSTEM :

 • A camera sensor-based adaptive traffic signal control has been proposed. This project results in a vehicle counting device that can detect traffic density. PCA is used to categorise cars into different groups. • The Smart Vehicle Over Speeding Detector detects the driving conditions to achieve good detection accuracy. • Over speeding vehicles are tracked and reported to the relevant authority using the proposed device., thus avoiding accidents. • The proposed STSC system is designed by a unified system architecture with an RSU middleware which organized by modular functional design. • In the place of radar speed detector here IR sensors are used to detect the over speed and an LCD display along with server computer to display the required number plate of a vehicle.

 ADVANTAGE :

 • Easy to use. • It has a simple design. • This system may reduce manpower involvement in traffic management systems. • System reliable. • Helps to control accident. • The human traffic controllers are used mostly as a solution to the congestion caused by drastic change in traffic dynamics; malfunctioning traffic signals or to give right of way to priority/emergency vehicles such as fire trucks, ambulances, police responding to duty call, etc. • The remote control mode is used to grant access to emergency vehicles and whenever it becomes necessary for human conductors to step in (example, due to sensor malfunctioning).
