An optimized solar traffic control and alert system using wireless sensor networks

Abstract : The optimized solar traffic light control and alert system provides the better approach for traffic congestion. The system is composed of wireless modem and solar panel designed inside the modem itself. The design makes use of solar energy rather electrical energy which makes it energy efficient. The wireless modem tracks the vehicle in highway and lights the vehicle with the help of solar panel. The solar panel is composed of solar tracker that helps to detect the vehicle in highway. The system also helps to avoid the accidents in highways and also sends the SMS to respective RTO authority .the approached system uses solar energy as a major source which makes it economic The main aim behind this system is to control the accidents in broad section of highway with optimal use of solar energy.

 EXISTING SYSTEM :

 ? Existing systems do not support any type of real time information exchange or interactive communication for adapting to changes in their surroundings. ? However, such a system requires not only the necessary communication infrastructure but also specific sensors to understand those changes. ? Due to increase of environmental concerns, lighting control systems will play an important role in reduction of energy consumption of the lighting without impending comfort goals. ? Automatic Street Light Control System is a simple and powerful concept, which uses transistor as a switch to switch ON and OFF the street light automatically.

 DISADVANTAGE :

 ? The energy is the single most important parameter to consider when assessing the impacts of technical systems on the environment. ? Therefore people need to be very safe and secure. In order to address this problem, Lighting appears to be major solution in highways. ? Moreover, the circuit is carefully designed to avoid common problems like overload, relay chattering and inductive kick back in relay. ? While building a software-controlled road lighting test bed, various research problems are addressed. ? This system will address community issues concerning poor visibility during winter time by the use of high-visibility LEDs.

 PROPOSED SYSTEM :

 • A solar light pole that stays on all night long, a control system is proposed to save battery energy and provides light efficiently. • The proposed system is particularly suitable for street lighting in urban and rural areas where the traffic is low at a given range of time. • The main purpose of road lighting system should be to consider information regarding transportation via sensor data and take necessary action. • The purpose behind establishing the architecture of the system is to build the connection between the IP network level and the wireless sensors at the physical level.

 ADVANTAGE :

 ? The Wireless Sensor is Operating Continuously to track the Vehicle, the Energy Efficiency of Wireless sensor becomes very low. ? In order to improve the Energy Efficiency of Wireless sensors, the Protocols like LEACH (Low Energy Adaptive Clustering Hierarchy) and PEGASIS (Power Efficient Gathering Sensor Information Systems) are implemented. ? The source of light has moved from conventional source of energy to green source of energy where solar panel is used to light the roads and highways. ? The design makes use of solar energy rather electrical energy which makes it energy efficient.
