Traffic Collision Avoidance Systems (TCAS) are advanced safety technologies designed to prevent accidents between vehicles. These systems use sensors, cameras, and radar to monitor the surrounding environment, detecting potential collisions with other vehicles, pedestrians, or obstacles. When a risk is identified, TCAS can alert the driver through visual or auditory warnings. In some cases, TCAS can take automatic actions, such as applying brakes or steering to avoid a crash. These systems are increasingly integrated into modern vehicles, contributing to road safety and reducing the likelihood of serious injuries. They are part of a broader movement towards autonomous driving technologies.
