Coordinating Timing and Data Fusion in an Emergency Vehicle Detection Use Case

This use case demonstrates the implementation of an Emergency Vehicle Detection (EVD) system using Lingua Franca, with support from the edgeai-python library. The system combines Audio Classification and Object Detection models to identify fire trucks approaching an intersection.

When the outputs of these models are fused and confirm the presence of a fire truck, the system triggers an actuation to prioritize the emergency vehicle by:

1. Changing the traffic light to green on the lane where the emergency vehicle is approaching (if it is currently red), or
2. Extending the green light duration to ensure the emergency vehicle passes through the intersection smoothly.

This use case addresses the Traffic Signal Preemption challenge, where traffic signals dynamically adapt to provide priority for emergency vehicles, ensuring their swift and safe passage through intersections.
