V2X Server Geofencing for Emergency Vehicle Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle-to-everything (V2X) communication systems lack effective mechanisms to enhance road safety by efficiently managing interactions between vehicles, infrastructure, and pedestrians, particularly in emergency situations, leading to potential congestion and inadequate response coordination.
Innovation Solution
Implementing a centralized V2X server that assigns geofencing areas along the projected path of emergency vehicles, identifies relevant V2X components within these areas, and sends notifications to improve traffic awareness and coordinate responses, while applying policies to manage call congestion.

Engineering Contradiction Analysis
1Reliability
If V2X communication systems are expanded to include more emergency services and infrastructure components, then road safety and emergency response capability are improved, but system complexity and call congestion increase
Solution Approach 1:
The system segments the service area into multiple geofenced regions along the emergency vehicle's projected path. Each geofence area can be independently managed and notified to relevant V2X components, reducing the complexity of managing all components simultaneously while improving coordinated response.
Solution Approach 2:
The V2X server acts as an intermediary that receives emergency calls, determines projected paths, identifies relevant V2X components within geofenced areas, and sends targeted notifications. This intermediary function reduces call congestion by pre-processing and routing information efficiently before it reaches individual components.
2Productivity
If geofencing areas are assigned along the projected path of emergency vehicles, then communication efficiency and targeted notifications are improved, but calculation time and processing requirements increase
Solution Approach 1:
The system calculates and assigns geofencing areas along the projected path in advance before the emergency vehicle reaches those locations. This preliminary action allows the system to prepare notifications ahead of time, reducing real-time processing requirements and improving communication efficiency when the vehicle approaches each zone.

AI summary
Techniques are described herein for improving road safety use cases in a vehicle-to-everything (V2X) communication environment. The techniques include assigning of a plurality of calculated/precalculated geofencing areas on a projected path of a responding emergency vehicle. With the assigned geofencing areas, a remote management network such as a V2X communications server may identify the V2X components (user equipment, traffic lights, vehicle embedded devices, etc.) and send notifications to the identified V2X components in each assigned geofencing area and at different timing periods. The identification of the V2X components and the sending of the notifications at different timing periods improve the traffic awareness between the V2X components in the V2X communication environment.
