## Overview

This repository combines a sensor-based pothole classifier with a browser dashboard for location, routing, and hazard alerts. The user journey is: start detection, send motion readings to the Flask prediction endpoint, publish predictions to Firebase, and show a warning when a pothole is reported; the dashboard also tracks GPS and draws routes. Separately, pothole.py contains dataset training and a Firebase-backed proximity-alert flow. The README describes additional preprocessing and dashboard features, but the excerpts do not show all their implementation details.
