Abstract Driver Fatigue is one of the major reasons causing most fatal road accidents around the world. This shows that in the transportation industry specially, where a heavy vehicle driver is often open to hours of monotonous driving which causes fatigue without frequent rest period. Due to the frequent driver fatigue occurrence, this has become an area of great socio economic concern. Consequently, it is very essential to design a road accidents prevention system by detecting driver’s drowsiness, which determines the level of driver inattention and give a warning when an impending hazard exists. In this paper the aim is to design a prototype system which detects driver’s drowsiness based on eye blinking to prevent road accidents.

1. Introduction Vehicle accident is one of the leading causes of death in the world. It is occurring due to poor indication of sign boards, drowsy state and drunken state. Most accidents are minor, such as sideswipes and rear end hits. But some, such as head on collisions can kill peoples instantaneously. Vehicle accidents happen all the time one drive down the freeway can attest to that. To avoid getting in to one accident, you need to account safety for yourself as well as for those who are around the drive way. It is obvious that now a day’s fatality rate is increases due to car accidents. Most of the time this occurs because of drunken driver, over speed, fatigue, driving during bad weather ,drowsy driver and drivers extra activities while driving such as talking on a cellphone, reading magazines, talking with passengers etc. But in this project vehicle accidents caused by drowsy drivers and deal with the scientific technique to overcome this problem. Drowsiness, which may also be referred to as sleepiness, is a naturally occurring bio physiological process. Although it is possible for a person to be fatigued without being drowsy, drowsiness may be a product of a variety of factors, including fatigue. Therefore, the difference between the concepts of fatigue and drowsiness is important. One of the most dangerous out comes of driver drowsiness is rapid onset micro sleeps. The project mainly emphasis on an eye glass attachable alarm signal device for drivers, preventing them to fall asleep while driving. It is designed both for day time and for night time driving. The system designed in this project, will detect driver drowsiness. Once drowsiness is detected then buzzer will on and turns the vehicle ignition off. Then vehicle will stop immediately.

2. Statement of the problem Driver fatigue is a significant factor in a large number of vehicle accidents. The development of technologies for detecting or preventing drowsiness at the wheel is a major challenge in the field of accident avoidance systems. Because of the hazard that Drowsiness presents on the road, methods need to be developed for counteracting its affects. In today’s world where science has made amazing advances so have the recent cars. These cars are more advanced than ever. But now a days, due to driver drowsiness accidents are increasing on daily bases. Hence many of passengers and drivers are died due to this case. This resulted in economic crises and reducing productive human power of the country. HARAMAYA INSTITUTE OF TECHNOLOGY

3. Objective 3.1 General objective  To prevent accident which caused by drowsiness.

3.2 Specific objective  To alert the driver who are at sleep.  To reduce accident that occur in the road or to reduce the amount of accidents caused by sleepy drivers.  To save drivers and passengers life

4. Scope of the project Sleep related accidents solved or reduced by designing the sensor which is called eye blink sensor. The system works in the car for the driver who drives the car during night and also day time. But it is mostly used by night time drivers because mostly drowsiness becomes high in night time by nature. This sensor senses the eye position either closed or open mode. Then, if eye is in closed mode the sensor output is high and gives to microcontroller in order to give alarm sound for preventing that accident which is result of drowsiness driver. Here, the main scope of this project is to reduce the accidents in cause of driver drowsiness. The system does not prevent another accidents which are not in cause of drowsiness driver.

5. Literature review Sensing of physiological characteristics is the possible techniques for detecting drowsiness in drivers. A man who is Neeta Parmer detect drowsiness of drivers in Ryerson University by this technique. He illuminates the driver’s face using a 60W light source. The light source is placed in such a way that the maximum light being reflected back is from the face. To prevent the light source from distracting the driver, he uses an 850nm filter over the source. Since 850nm falls in the infrared region, the illumination cannot be detected by the human eye, and hence does not agitate the driver. The system consists of camera that takes images of the driver’s face. Based on the use of image processing technology that will be able to accommodate individual driver differences. The camera is placed in front of the driver, approximately 30 cm away from the face. The camera must be positioned such that the following criteria are met:  The driver’s face takes up the majority of the image. HARAMAYA INSTITUTE OF TECHNOLOGY

B.SC THESIS PROPOSAL  The driver’s face is approximately in the center of the image. The greyscale image is converting to a binary image via thresholding. The output binary image has values of 0 (black) for all pixels in the original image with luminance less than level and 1 (white) for all other pixels. The criteria used in choosing the correct threshold was based on the idea that the binary image of the driver’s face should be majority white, allowing a few black blobs from the eyes, nose and/or lips [3]

6. Significance The main aim of the project is that designing an accident avoidance systems for fatal, accidents which are caused by drowsy drivers. The focus will be placed on designing a system that will accurately monitor the open or closed state of the driver’s eyes in real-time. According to this project to diminish car accidents eye blink sensor must be designed to monitor the movement of driver eyes and alerting buzzer circuit which alerts if the blinking rate of the driver eye is changed. The most important benefit of an in vehicle system is to promote safety.

7. Methodology 7.1 Eye blink sensor design An eye blink sensor senses either the driver is sleep or not by using IR sensor that designed in this project. The sensor consists of two parts. They are IR transmitter and IR receiver. The IR transmitter is used to transmit the infrared rays in the driver eye and The IR receiver is used to receive the reflected infrared rays of eye. If the eye is closed means the output of IR receiver is high otherwise the IR receiver output is low. This to know the eye is closing or opening position. The eye blink sensor is connected through microcontroller, by using this eye sensor to sense blinking time of eye, eye blinking data is send to the microcontroller. The micro controller compare the overall data and send warning signal to the driver circuitry system, then it gives alert the entire system. The block diagram depicts the total blue print of the project. The total essence and the functioning of the project is represented in a single block diagram. The block diagram mainly consists of eight parts. They include:  LCD  GPRS  LCD HARAMAYA INSTITUTE OF TECHNOLOGY

In this project we will use LCD in order to display a certain additional information to easily understand the system during simulation in proteus.

7.3 Buzzer A buzzer or beeper is an audio signaling device, which may be mechanical, electromechanical, or piezo electric. Typical uses of buzzers and beepers include alarm devices, timers and confirmation of user input such as a mouse click or keystroke.

7.4 Power supply All power supplies have a power input, which receives energy from the energy source, and a power output that delivers energy to the load. The power supply circuits built using filters, rectifiers, and then voltage regulators. Starting with an ac voltage, a steady dc voltage is obtained by rectifying the ac voltage, then filtering to a dc level, and finally, regulating to obtain a desired fixed dc voltage. The regulation is usually obtained from an IC voltage regulator unit, which takes a dc voltage and provides a somewhat lower dc voltage, which remains the same even if the input dc voltage varies, or the output load connected to the dc voltage changes
