Phase 4.1: Build Emergency Vehicle Detector & Corridor Logic

[archittmittal]

Goal

Automatically detect emergency vehicles and create green corridors.

Tasks

• Extend YOLOv8 logic to specifically flag 'bus' or 'truck' classes that display emergency visual cues (e.g., flashing lights, using OpenCV color filtering) or use audio detection (sirens).
• Implement pathfinding (via NetworkX) from current location to destination.
• Implement corridor override logic: force green signals on the path, overriding the RL agent temporarily.
• Release the override once the vehicle passes.

Deliverable

A working emergency preemption system that clears traffic dynamically.
