1. Understanding Autonomous Vehicles
What Are Self-Driving Cars?
- Vehicles that use AI, sensors, and advanced computing to navigate without human intervention.
- Operate using deep learning algorithms, cameras, radar, and LiDAR sensors.
Levels of Vehicle Autonomy (SAE Levels)
- Level 0: No automation, full human control.
- Level 1: Driver assistance (adaptive cruise control).
- Level 2: Partial automation (lane-keeping, autopilot features).
- Level 3: Conditional automation (driver required in certain situations).
- Level 4: High automation (fully autonomous in controlled environments).
- Level 5: Full automation (no human intervention needed anywhere).
2. The Role of AI in Autonomous Transportation
How AI Powers Self-Driving Cars
- Machine Learning: Processes vast amounts of data to recognize road patterns.
- Computer Vision: Uses cameras and sensors to detect objects, lanes, and pedestrians.
