This project presents the design and implementation of a real-time GPS-based online ambulance booking and dispatch system aimed at improving emergency medical services. Many regions face delays due to manual ambulance allocation, lack of tracking, and poor coordination. To solve this, the system uses a Flask backend, React frontend, and live geolocation tracking to automatically assign the nearest ambulance within a 50 km radius. It provides real-time tracking, ETA updates, OTP-based secure patient pickup, and complete trip lifecycle management. The system reduces response time, improves transparency, ensures secure matching, and supports efficient ambulance management in real-world emergency situations
