Dynamic Lane Permission Control for Connected Traffic Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in the context of 5G NR, lack efficient mechanisms for dynamic lane management and traffic optimization in vehicular networks.
Innovation Solution
The implementation of a method where vehicles can transmit lane use request messages to a network entity, which then grants permission based on lane and vehicle information, allowing for dynamic lane use and traffic balancing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional wireless communication systems are used for vehicular networks, then basic communication functionality is provided, but dynamic lane management and traffic optimization are not achieved
Solution Approach 1:
The patent implements dynamic lane management by enabling real-time communication between vehicles and network entities through wireless messaging. The system dynamically assigns lane permissions based on current traffic conditions, vehicle requests, and network entity decisions, transforming static lane assignments into adaptive, time-varying configurations that optimize traffic flow.
Solution Approach 2:
The system establishes a feedback loop where vehicles transmit lane use requests to network entities, which respond with grant or denial messages. This closed-loop communication enables continuous monitoring and adjustment of lane assignments based on actual traffic conditions, vehicle priorities, and road infrastructure status, thereby achieving traffic optimization.
2Productivity
If dynamic lane use permission system is implemented, then traffic congestion is reduced and road infrastructure utilization is improved, but system complexity increases
Solution Approach 1:
The network entity serves as an intermediary between vehicles and road infrastructure, centralizing the decision-making process for lane assignments. This mediator receives requests from vehicles, evaluates them against current traffic conditions and infrastructure status, and issues binding decisions, thereby simplifying the overall system architecture while enabling complex dynamic management.
Solution Approach 2:
The patent segments the traffic management function into distinct components: vehicle-side request generation, network entity decision-making, and infrastructure-side permission enforcement. This segmentation allows each component to be optimized independently and facilitates modular implementation, reducing overall system complexity while maintaining dynamic management capabilities.
3Reliability
If lane use permission is granted based on vehicle information and lane information, then safe and optimized routing is achieved, but communication overhead increases
Solution Approach 1:
The system implements partial action by only initiating communication when vehicles need lane permission changes or when traffic conditions warrant reassignment. Rather than continuous communication, the system activates messaging only when necessary, reducing overall communication overhead while maintaining safety through timely information exchange.

AI summary
A vehicle may transmit, to a network entity, a lane use request message associated with a lane for the vehicle. The network entity may identify lane information associated with a lane for a vehicle. The network entity may identify vehicle information associated with the vehicle. The network entity may transmit, to the vehicle, and the vehicle may receive, from the network entity, a lane use grant message based on at least one of the identified lane information or the identified vehicle information. The lane use grant message may be indicative of a permission for the vehicle to use the lane. The vehicle may not be permitted to use the lane without the permission. The lane may correspond to a flexible direction lane, an emergency lane, a road shoulder, an HOV lane, or a passing lane.
