IoT-Enabled Ultrasonic Sensing and Bidirectional Alert System for Blind-Curve Accident Prevention

Blind Curves on country and hilly roads are always more dangerous than straight ones because limited line-of-sight prevents drivers from perceiving oncoming vehicles, while the lack of direct vehicle-to-vehicle communication. Common measures such as convex mirrors and warning signs can increase driver awareness of dangerous traffic situations, however, they are unable to provide dynamic, distance-based warnings that adapt to the presence of approaching vehicles.
