        abstract = {Fixed speed breakers slow every vehicle that passes over them, regardless of how fast the vehicle is actually moving. They also slow emergency vehicles, where every second matters. This paper presents a low-cost prototype of an adaptive speed breaker that estimates the speed of an approaching vehicle using a pair of ultrasonic sensors, then raises a hinged road panel to a height that is proportional to the measured speed. Slow vehicles experience little or no bump. Fast vehicles encounter a fully raised breaker, capped at a forty-five-degree servo angle so the road remains passable. Emergency vehicles carry a passive RFID tag, and when that tag is read the breaker drops flat and stays flat for a fifteen-second window. A wireless dashboard served from the on-board microcontroller logs every vehicle that crosses, along with its estimated speed and the angle that was applied. A scaled hardware prototype was constructed and used to validate the control law with nine test passes. The system behaved as expected in all nine runs and the dashboard logged the values without loss. The paper also reports the mechanical design carried out in SolidWorks, including the scissor linkage geometry and the steels chosen for the load-bearing parts.},
