Intellectual Speed Control with GPS and Radar for Emergency Vehicle Pre-Emption

Abstract
:According to several statistics the majority of the Car accidents are caused by highspeedand disrespect of the inter-vehicles security distance. In spite of this, more than 60% of drivers do not comply with speed limits on urban roads or trunk roads. The worst situation is when a trunk road passes through a village. There, almost 80% of drivers break the speed limit. In order to give to drivers the means for controlling the speed of their cars, several constructors have developed various systems such as the speed limiter or regulator already present in some cars. In this field, research continues to give more effective systems, like speed regulator systems with GPS (Global Positioning System) which allows to adapt the car velocity to that authorized in its localization zone. In this paper we describe an Intelligent Cruise Control with GPS and Radar (ICCGR) that combine GPS and radar systems to adapt the vehicle speed to respect the speed limitation and to avoid running up against others vehicles. The system integrates a GPS subsystem which makes it possible to locate the car and to determine authorized speed in its zone of localization. The radar subsystem detects any obstacle In front of the vehicle and gives the optimal speed to avoid the most dangerous one. A traffic signal pre-emption system,and a related method for its use, using differential global positioning system measurements for accurate monitoring of the position , speed and direction of an emergency or service vehicle.
Keywords: GPS, Radar systems, ICCGR.
I.Introduction
The major threats to the world are pollution ,global warming, road accident etc. This project provides solution prevent road accident, and allow priority to the emergency vehicles. Accidents may occur due to various reasons one the main reason is due to over speed. We restrict the speed of the vehicles automatically when it enter the specified zone using IR. The transmitter is specified in a particular area and receiver is fixed at the top of the vehicle. If the speed is less or equal to the given speed, the system does not get activated. After the vehicle leaves the specified location it automatically return to the default position. Therefore, the accident can be reduced to some extent. By using IR transmitter and receivers can prevent accidents at a specified zone only. In RF there are two part transmitter and receiver in the transistor when press the micro switches key given some input of microcontroller , the microcontroller check the key input whose key press and what is the data or information sending after this process the microcontroller1 encoded the input by the RE module the receiver the data by RE module and collected by receiver microcontroller and the microcontroller decoding the information signal and display on the seven segment and microcontroller sending the data in dc Motor, and motors start the receiver part send feedback which data is receives ,sending by the RF module again the transmitter RF module receive feedback information and decoding by microcontroller and display on LCD (liquid crystal display). It’s whole process based on the frequency modulation. In order to avoid accidents at all places by using GPS system.
