Today in a fast-moving world, all peoples do not have self-control. These people are driving vehicles at high speed. So the police are not able to control all those things. This document provides a way to control speed without harming others. The driver does not control anything during those places; The controls are automatically taken by the use of the electronic system. In this project we use RF to indicate the areas of speed limit that is placed in front of and behind the restricted areas. The RF receiver is placed inside the vehicle. The speed is acquired with the help of speedometer in the vehicle. The controller compares the speed. If it exceeds the limited speed the driver alerts the driver and the controls are automatically taken. If this message is not answered, an information along with the vehicle number is transmitted to the nearest police station by using GSM and the amount of the fine is collected at the nearest toll gate.
It is important to know the density of road traffic in real time, especially in mega cities for signal control and effective traffic management. In recent years, video surveillance and surveillance systems have been widely used in traffic management. Traffic control is a very difficult task for the traffic control department, especially in metropolitan cities. The project is designed to verify the density of traffic at a particular location and the information is transmitted to the traffic control station. This project uses a regulated 5V, 500mA power supply. 7805 Three-terminal voltage regulator is used for voltage regulation. The Bridge Type Full Wave Rectifier is used to rectify the set transformer secondary side out of the 230 / 12V downstream transformer.
