All over the world, road transportation has increased tremendously. The issue with increased road transportation is undesirable accidents. Accidents are highest in India amongst other countries in the world. The actual number of casualties due to accidents may be higher than documented. There are some particular places where accidents occur more, they are road crossings, turns on highways etc. It is required to minimise the accidents with an intelligent system that alerts before the occurrence of accidents. Also, the accidents on highways can be prevented by understanding the psychological state of driver. This project has proposed a smart system for accident prevention that is an ideal concept for smart roads. This smart system uses sensors to send digital data using internet of things (IoT) to take immediate actions under emergency conditions and to communicate through wireless protocol. The main object of the propose system is to prevent accident by sensing the nearby zones through signal or message alert through Wi-Fi technology. If narrow Bridge zone nearer to vehicles within 100 meters it will give alert notification to mobile through Wi-Fi. After this indication the person reduces the speed of the vehicle. Similarly, if school zone is nearer to vehicles within 100 meters it will give alert notification to mobile through Wi-Fi. After this indication the person can slow down the vehicle. Same as if Fog zone nearer to vehicles within 100 meters it will give message alert to mobile through Wi-Fi. After this indication the person reduces the speed of the vehicle. By this indication we can reduce the accidents on Highways. In this project we are using IOT module ESP 8266, AT89S52, switches. Here, in this project, IOT module is connected to the controller and using internet from any place speed can be controlled. This project uses regulated 5V, 1A power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac output of secondary of 230/12V step down transformer.
