Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intelligent traffic management systems face challenges in efficiently utilizing newly installed Vehicle-to-Vehicle (V2V), Vehicle-to-Infrastructure (V2I), and Vehicle-to-Everything (V2X) communication infrastructure to optimize traffic flow and data transmission, particularly at intersections where vehicles are stationary or moving at low speeds.
Innovation Solution
User equipment and infrastructure equipment are designed to switch between communication protocols based on speed, using a higher bandwidth protocol when stationary and a lower bandwidth protocol when moving, allowing for reliable and efficient data transfer with infrastructure equipment such as traffic lights, enabling seamless communication and data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a higher bandwidth communication protocol is used when user equipment is stationary or moving at low speeds, then data transmission reliability and bandwidth are improved, but device complexity and energy consumption increase
Solution Approach 1:
The system dynamically switches between communication protocols based on the user equipment's speed. When the UE is stationary or moving at low speeds (below threshold), the higher bandwidth first communication protocol is used. When the UE exceeds the speed threshold, the system transitions to the second communication protocol. This dynamic adaptation resolves the contradiction by only employing the more complex protocol when its benefits are needed.
Solution Approach 2:
The system changes the communication protocol parameter based on speed conditions. The controller circuitry monitors the speed of the user equipment and switches between different communication protocols (first protocol with higher bandwidth vs. second protocol) according to whether the speed is below or above a threshold value, optimizing performance while managing complexity.
2Productivity
If communication protocol switching is implemented based on speed, then bandwidth efficiency is improved, but device complexity increases
Solution Approach 1:
The communication system implements dynamic protocol selection based on real-time speed monitoring. The controller circuitry automatically determines whether to use the first or second communication protocol by comparing the UE's current speed against a threshold, enabling bandwidth optimization without requiring complex manual configuration or intervention.
Solution Approach 2:
The user equipment autonomously manages its own communication protocol selection based on its speed. The controller circuitry performs self-monitoring of speed and self-decision on which communication protocol to use, eliminating the need for external control or complex infrastructure-based protocol management.
3Speed
If the higher bandwidth protocol is used continuously, then data transmission speed is improved, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts energy consumption by selecting communication protocols based on speed conditions. The higher bandwidth first communication protocol is only activated when the UE is stationary or moving at low speeds, where it provides meaningful benefit. When the UE is moving at higher speeds, the system switches to the second protocol, reducing energy consumption without significantly impacting data transmission effectiveness.
