🚗🤖 Autonomous Vehicles (AVs): Driving the Future of Transportation
Autonomous vehicles—also known as self-driving cars or driverless vehicles—use a combination of sensors, AI, and real-time data to navigate roads without human input. From improving safety to transforming mobility services, AVs are a cornerstone of the next-generation transportation ecosystem.
🧠 What Are Autonomous Vehicles?
Autonomous vehicles are capable of:
-
Perceiving their environment using cameras, LiDAR, radar, and GPS.
-
Making decisions via AI algorithms and onboard computing systems.
-
Navigating without driver intervention, under varying road and traffic conditions.
📊 SAE Levels of Autonomy (0–5)
