Auto detecting signal using sensor in hair-pin bends for heavy vehicles

Abstract Considering the increase in road accidents in recent years, road accidents are accepted as an exceptional dimension of a serious problem. Accidents have occurred due to the fact that the driver's signal, particularly its faint curves, is particularly difficult when it comes to driving in mountainous areas, particularly in severe twists. The human factor can not do much to improve the drivers' awareness level and the stress experienced by the drivers. Hence, the intelligence system places roads to the roads of the hill to help drivers avoid the threat. This research created a system of stronger sensors that combined with a microprocessor to achieve a lower price, but the most reliable indicator. Infrared sensors installed at a specified height at the initial and closing section of the hard road are capable of detecting only a heavy vehicle. The IR sensor module consists mainly of Infra Red Transmitter and receiver, output Light Emitting Diode. Infra Red LED emits light, in the range of Infrared Frequency and IR light is invisible to us as its wavelength (700 nm–1 mm) is much higher than the visible light range. An IR sensor emits and/0r detects IR radiation to sense its surroundings, which is used as Obstacle detector is to transmit an infrared signal, this infrared signal bounces from the surface of an object and the signal is received at the infrared receiver. The use of microcontroller for generation and controlling logic of infrared signal helps the immediate collision calculation when approaching the range of the vehicle, thereby providing some controls for a warning LED. As a result, the driver is controlled by the driver.
