V2X Emergency Assistance Priority — Project proposal

Abstract

Project proposal. # Overview The **V2X Emergency Assistance Priority (EASP)** system uses **Vehicle-to-Everything (V2X)** communication to clear a path for emergency vehicles through congested traffic. When an ambulance, fire truck or police car is dispatched, it broadcasts its approach to the vehicles and traffic lights ahead of it — the surrounding traffic opens a dedicated lane, and the intersections along its route are handed over to it before it arrives. The goal is a measurable one: **minutes**. When an ambulance cannot reach its destination within four minutes, the likelihood of survival drops by about **30%**, and every additional minute of delay raises the mortality risk by **8–17%** across all emergencies. Conversely, cutting the response time by a single minute raises the survival rate by roughly **5.2%**. --- # Why V2X **Vehicle-to-Everything** lets a vehicle exchange information with everything around it — other vehicles, roadside infrastructure, pedestrians and networks. This project builds on two of its domains: - 🚘 **V2V (Vehicle-to-Vehicle)** — vehicles exchange speed, position, acceleration and direction directly with one another, which is what makes cooperative manoeuvres and collision avoidance possible. - 🚦 **V2I (Vehicle-to-Infrastructure)** — vehicles talk to traffic signals and intelligent transportation systems, receiving signal state and traffic conditions in real time. --- # System Architecture The solution is built from three cooperating sub-systems. ## 1. Emergency Declaration The sub-system that announces the emergency vehicle to everything in front of it. - The emergency vehicle broadcasts a signal to the traffic light and to every vehicle ahead of it on both lanes. - Receiving vehicles and the traffic light switch into **emergency mode** to begin forming a dedicated lane. - After verification, only the non-emergency vehicle that is actually obstructing the emergency vehicle receives a warning message with instructions, so it can shift safely to the other lane. Targeting only the blocking vehicle is deliberate: a broadcast that tells the whole road to move at once creates the congestion it is meant to remove. ## 2. Shift Handling The sub-system that makes the lane change safe once a vehicle has been asked to move. - Through **V2V**, the blocking vehicle exchanges its position and its intention to move with the vehicles in the adjacent lane. - The vehicle in the adjacent lane responds by adjusting its own position, opening a gap for a synchronized and coordinated movement. - Constant communication plus onboard sensing lets both vehicles complete the manoeuvre without any risk of collision. ## 3. Intersection Handling The sub-system that carries the emergency vehicle through junctions without stopping it. One road at the junction is treated as the **master road** and the crossing one as the **other road**, each with its own traffic light. The emergency vehicle broadcasts to the master traffic light, which reads its speed and location and negotiates with the crossing light: - **No emergency vehicle on the other road** — the master light opens and the other stays closed. - **An emergency vehicle on each road, different priorities** — the light serving the higher-priority vehicle opens first. - **An emergency vehicle on each road, equal priority** — the distance from each vehicle to its own light is computed, and the light for the closer one opens first. Once the emergency vehicle has passed, the intersection returns to normal mode. --- # Technologies - **V2V communication** — cooperative messaging between vehicles - **V2I communication** — vehicle-to-traffic-light coordination - **Embedded systems** — the on-board emergency, shift and intersection logic - **Intelligent traffic light control** — emergency mode and priority arbitration --- # Team | Member | Role | | --- | --- | | Al-Hasan Sharaf El-Deen | Team Leader | | Omar Ashour | Member | | Mohamed Mostafa Gad | Member
