V2X Traffic Management for Emergency Vehicle Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traffic management systems are inefficient in facilitating the movement of priority vehicles, such as emergency vehicles, through roads and intersections, relying on specialized infrastructure-based equipment with limited communication capabilities.
Innovation Solution
A cooperative and connected traffic management system that enables vehicles with V2X communication capabilities to adapt their movement and routing, and coordinates with traffic control devices to prioritize the passage of priority vehicles, while also considering vulnerable road users, using modules like network data acquisition, sensor data acquisition, collaboration group formation, and preemption/prioritization and path planning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If specialized infrastructure-based equipment with limited communication capabilities is used, then the system can provide priority vehicle passage, but the system efficiency and communication capability are limited
Solution Approach 1:
The patent applies universality by enabling standard V2X communication infrastructure to serve multiple functions: general traffic communication and priority vehicle passage coordination. Instead of requiring specialized infrastructure, the system uses existing vehicle-to-everything communication capabilities to achieve both universal traffic management and priority vehicle assistance, thereby improving system efficiency while maintaining reliable priority passage.
2Reliability
If preemption systems with specialized infrastructure are used, then priority vehicles can be facilitated, but the device complexity and cost increase
Solution Approach 1:
The patent extracts the priority vehicle facilitation function from specialized infrastructure and relocates it to standard V2X communication systems. By taking out the core functionality (priority passage coordination) and implementing it through existing communication protocols and vehicle systems, the system reduces infrastructure complexity and cost while maintaining reliable priority vehicle facilitation.
3Reliability
If existing preemption systems are used, then priority passage can be achieved, but the adaptability to real-time traffic conditions is limited
Solution Approach 1:
The patent applies dynamics by implementing a real-time adaptive system that continuously monitors traffic conditions, vehicle locations, and road status through V2X communications. The system dynamically adjusts priority passage decisions based on current conditions such as traffic density, road blockages, and vehicle speeds, thereby improving adaptability to real-time traffic conditions while maintaining reliable priority passage through coordinated control.

AI summary
The disclosure relates to systems, methods, and devices for managing traffic through a road segment and/or intersection. The traffic management system may place traffic objects in a collaboration group for coordinating movements in the road segment and/or intersection in response to a received indication that an emergency vehicle has a planned route that includes the road segment and/or intersection. The traffic management system may determine a movement plan for each traffic object in the collaboration group based on received measurements about the road segment and the planned route of the emergency vehicle. The traffic management system may control a transmitter to send the movement plan to each traffic object in the collaboration group.
