Drunken driving and rash driving prevention system

As is needless to say; a majority of accidents, which occur, are due to drunk driving. As such, there is no effective mechanism to prevent this. Here we have designed an integrated system for the same purpose. Alcohol content in the driver's body is detected by means of an infrared breath analyzer placed at the steering wheel. An infrared cell directs infrared energy through the sample and any unabsorbed energy at the other side is detected. The higher the concentration of ethanol, the more infrared absorption occurs (in much the same way that a sunglass lens absorbs visible light, alcohol absorbs infrared light). Thus the alcohol level of the driver is continuously monitored and calibrated on a scale. When it exceeds a particular limit the fuel supply is cutoff. If the device is removed also, the fuel supply will be automatically cut off or an alarm is sounded depending upon the requirement. This does not happen abruptly and special indicators are fixed at the back to avoid inconvenience to other drivers using the highway signals. Further, in this paper we intend to present the designed mechanical system for controlling the speed of vehicles in densely populated regions. Advance digital maps have the capacity for real-time updating duly including information on areas where speed limits should be reduced due to adverse weather conditions or around accident scenes and road-works. This paper also discusses the on-board vision system by evaluating the surroundings of the vehicles and thereby improving the safety and efficiency of driving. It lies on important ability for various recognitions like traffic signals, signs and pedestrians are presented. Frame work for integration of sensors and control module in a scalable multi-agent system is provided. A SMS which contains the current GPS location of the vehicle is sent via a GSM module to the police control room to alert the police. The system is foolproof and the driver cannot tamper with it easily. Thus it provides an effective and cost effective solution for the problem of drunk driving in vehicles.
