Hi Spike
The system probably varies between different brands of robo cars.
But, asking an AI how it does it  -----

Phind AI:
Self-driving vehicles use sophisticated computer vision systems to reliably
detect and classify traffic signals among various environmental light
sources. This complex process involves multiple layers of detection and
verification to ensure accurate signal recognition.

###  Core Detection Methods

1. **Visual Processing Pipeline**  - High-resolution cameras capture
detailed images of the scene
  - Advanced algorithms detect circular shapes characteristic of traffic
lights
  - Color analysis distinguishes between red, yellow, and green signals
  - Multiple frames are analyzed to confirm consistent readings


2. **Signal Verification Techniques**  - Position tracking: Traffic lights
appear in predictable locations
  - Pattern recognition: Known shapes and arrangements of signals
  - Motion analysis: Traffic lights remain stationary
  - Contextual understanding: Relationship to intersections and roads

###  Safety Measures

1. **Multiple Confirmation Systems**  - Requires agreement between multiple
detection methods
  - Implements voting systems among different sensors
  - Maintains historical context of signal states
  - Continuously verifies detections

2. **Error Prevention**  - Regular software updates
  - Sensor calibration checks
  - Weather condition monitoring
  - Fallback procedures for uncertain situations

The reliability of these systems comes from their multi-layered approach,
combining visual detection with contextual awareness and sensor fusion. By
verifying traffic signals through multiple independent methods, autonomous
vehicles can maintain safe operation even in challenging environmental
conditions.
