The main aim of this project is to construct a smart vehicle system with minimizing the limitations of existing methods and also enhancing the security of vehicles and human beings and also reduces the accidental injuries. smart vehicle system will entail a speed and other parameters of vehicle sensing mechanism which automatically messages to personal contacts with the details of vehicle position when an accident occurs using the GSM/GPRS system. The system also contains fire sensor and an eye blink sensor. A fire sensor, eye blink sensor which senses various parameters of the vehicle is connected to a microcontroller which detects when the abnormal conditions occur or any accidents occur then sends text message, using GSM technology, to the driver’s private contacts. The text send to various authorities contains the details of the vehicle and its position. If any ignition occurs in the vechicle ,then the fire sensor sends text to the driver’s selected contacts. The accidents and the accident injuries in the world is increasing in our day today life so there must be good and efficient control for the safety of human life violation of traffic rules drunk driving, careless driving are some causes of road accidents as we know we cannot stop the accidents but we can reduce the accidents by some precautionary measures. Road accident is most unwanted thing to happen to a road user, though they happen quite often. The most unfortunate thing is that we don’t learn from our mistakes on road. Most of the road users are quite well aware of the general rules and safety measures while using roads but it is only the laxity on part of road users, which cause accidents and crashes. Most of the fatal accidents occur due to over speeding. It is a natural psyche of humans to excel. But when we are sharing the road with other users we will always want to take a control. Increase in speed multiplies the risk of accident and severity of injury during accident. A vehicle moving on high speed will have greater impact during the crash and hence will cause more injuries. some deaths also happen due to the lack of immediate first aid. Another problem is that the lack of information about the vehicle position. So,in our project we have used GSM/GPRS modem to locate the exact position of the vehicle. We propose an intelligent vehicle system for accident prevention and making the world a much better and safe place to live.Passive IR sensor is reliable for detecting human or animals and this technique certainly can save lots of lives.Pre crash detection system must be equipped with combination of different sensors. Detecting humans or animals including obstacles will certainly give us a better solution to reduce the death of human in road crash. IMPACT OF THE PROPOSED SOLUTION: At present criteria, we cannot detect where the accident has occurred and hence no information related to it, leading to the death of an individual. The research work is going on for tracking the position of the vehicle even in dark clumsy areas where there is no network for receiving the signals. In this project GPS is used for tracking the position of the vehicle, GSM is used for sending the message. Hence with this project implementation we can detect the position of the vehicle where the accident has occurred so that we can provide the first aid as early as possible. This project presents vehicle accident detection and alert system with SMS to the user defined mobile numbers. The GPS tracking and GSM alert based algorithm is designed and implemented with LPC2148 MCU in embedded system domain. The proposed Vehicle accident detection system can track geographical information automatically and sends an alert SMS regarding accident. Experimental work has been carried out carefully. The result shows that higher sensitivity and accuracy is indeed achieved using this project. This made the project more user-friendly and reliable. The proposed method is verified to be highly beneficial for the automotive industry. The Rapid growth of technology and infrastructure has made our lives easier. The advent of technology has also increased the traffic hazards and the road accidents take place frequently which causes huge loss of life and property because of the poor emergency facilities. Our project will provide an optimum solution to this draw back. Microcontroller sends the alert message through the GSM MODEM including the location to police control room or a rescue team. So the police can immediately trace the location through the GPS MODEM, after receiving the information. Then after conforming the location necessary action will be taken. If the person meets with a small accident or if there is no serious threat to anyone`s life, then the alert message can be terminated by the driver by a switch provided in order to avoid wasting the valuable time of the medical rescue team. As there is a scope for improvement and as a future implementation we can add a wireless webcam for capturing the images which will help in providing driver`s assistance. The high demand of automobiles has also increased the traffic hazards and the road accidents. Life of the people is under high risk. This is because of the lack of best emergency facilities available in our country. An automatic alarm device for vehicle accidents is introduced in this project. This design is a system which can detect accidents in significantly less time and sends the basic information to first aid centre within a few seconds covering geographical coordinates, the time and angle in which a vehicle accident had occurred. This alert message is sent to the rescue team in a short time, which will help in saving the valuable lives. A Switch is also provided in order to terminate the sending of a message in rare case where there is no casualty, this can save the precious time of the medical rescue team. When the accident occurs the alert message is sent automatically to the rescue team and to the police station. The message is sent through the GSM module and the location of the accident is detected with the help of the GPS module. This application provides the optimum solution to poor emergency facilities provided to the roads accidents in the most feasible way.
