Autonomous vehicles represent an advanced transportation technology that can sense their environment and navigate without human intervention through sophisticated integration of artificial intelligence, sensors, and control systems. These self-driving vehicles interpret sensory information to identify navigation paths, obstacles, traffic conditions, and relevant signage, making driving decisions that traditionally required human intelligence and reflexes.
Unlike conventional vehicles requiring constant human control, autonomous vehicles operate on a spectrum of automation ranging from driver assistance features to full autonomy where no human attention is necessary. This technological evolution promises to fundamentally transform mobility by enhancing safety, improving traffic efficiency, expanding transportation access, reducing environmental impacts, and liberating human time otherwise spent on driving tasks.
