Injuries caused by the operator's negligence or lack of attention by laborers to the surrounding environment during the road construction process are one of the main reasons for accidents in road construction sites. The use of sound cues in construction vehicles is a widely used method to alert people in the vicinity. However, in real-world applications, the voice alert of the vehicle may not be efficient in letting people notice it due to the noise of the construction site and people wearing sound insulation equipment to protect their hearing. Vibration might be a better way to apply in construction sites that are less affected by surrounding noise, and it can indicate the potential hazard direction to people. On the other hand, ultrasonic sensors are a well-developed technology used for distance and size measurement in homogeneous materials. With recent advancements in microprocessor ability, detection and distance estimation using ultrasonic sensors are possible. The aim of this project is to build an alert device that combines ultrasonic sensors with vibration sensors to notify people of the direction in which an object is approaching and to be aware of the potential hazard.
