Nowadays the drivers drive vehicles at high speed even in speed limited areas without considering the safety of the public. Most of the road accidents occur due to over speeding and traffic violation. The traffic police are not able to control them with full effect. Also, it is not practical to monitor these areas throughout. Even though we have signboards at all the riskier zones like schools and hospitals but most of the drivers won’t look into them. Our project paves way for controlling the speed of the vehicles within certain limits in restricted zones without interruption of the drivers. Here, we make a survey on the model based on wireless technology by which we will be able to control the speed of the vehicle. This project composed of two separate units namely the zone status transmitter unit and the receiver unit. The RFID reader is attached along with the vehicle and the RFID Tag with these Zones. These tags are programmed to send a coded signal when the reader comes in proximity. A controlling module in the vehicle then takes the decision and control the speed accordingly by making use of the pulse width modulation concept Whenever the vehicles enter into these zones their receivers will receive this code and the speed of the vehicles is controlled automatically with the help of the speed controller attached to microcontroller unit present inside the vehicle. The tags are placed at the beginning and the end of the regions for which the speed should be reduced.
