Intelligent instruments are used in every part of our lives. It won’t take much time to realize that most of our tasks are being done by Electronics. They will perform one of the most complicated tasks that a person does in a day, that of driving a vehicle. As the days of manned driving are getting extremely numbered, so are those of traffic jams, dangerous and rough drivers and more importantly, accidents. According to Mr Willie D. Jones in the IEEE SPECTRUM magazine (September 2001), a person dies in a car crash every second. Automation of the driving control of vehicles is one of the most vital needs of the hour. This technology can very well implement what was absent before, controlled lane driving. The ultimate aim of this project is to automatically control the speed of the vehicles at speed restricted areas such as school and hospital zone etc. This project is mainly developed to avoid accidents due to high speed vehicles and also to enable the public to cross the road without any danger from high speed vehicles. Usually the drivers drive the vehicles at high speed without considering the public in speed limited areas too. Even though the traffic police control them we cannot achieve full response from them. Also it is not possible to monitor those areas at all time to regulate their speed. Thus this project paves way for controlling the speed of the vehicles within certain limit in those restricted zones without the interruption of the drivers. Here we use RF communication method for controlling purpose. In order to implement this in public then we want to attach the RF receiver along with the vehicle and the Transmitter with these Zones. These transmitters are programmed to send the coded signals continuously with certain delay in between. Whenever the vehicles enter into these zones their receivers will receive this code and then the speed of the vehicles is controlled automatically by taking control action in the throttle valve. This will reduce the over speed to the desired speed limit.
