The Collision Warning System (CWS) for Autonomous Vehicles (AVs) in the TiHAN Testbed is designed to enhance vehicle safety by using standalone sensors and integrated ones . It detects potential collisions by monitoring the vehicle's surroundings, identifying obstacles, and calculating risk. The system triggers visual or auditory alerts to warn the driver or initiate automatic interventions like braking or steering adjustments. TiHAN’s controlled environment allows testing CWS under various dynamic conditions, ensuring reliability and effectiveness in preventing accidents and improving the overall safety of autonomous vehicles
