Solution Overview

Problem

Conventional traffic control devices, such as freeway on-ramp lights and traffic lights, require invasive and costly installation processes, are prone to damage from weather conditions, and suffer from reduced functionality due to external factors, leading to inefficiencies and increased traffic accidents.

Innovation Solution

Implementing sidelink positioning-based traffic control systems that utilize network entities like roadside units to receive position data from vehicles via sidelink communications, enabling real-time road congestion analysis and control of traffic devices, such as on-ramp lights and smart traffic lights, to optimize traffic flow and reduce accidents.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional traffic control devices use invasive sensors installed under road surfaces, then traffic control functionality is achieved, but installation cost and complexity increase significantly

Engineering Contradiction:

Improvetraffic control functionalityVSAvoidinstallation process

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses wireless communication devices in vehicles as intermediaries to provide traffic control data. Instead of installing sensors under the road, the system receives position data from vehicles' onboard wireless devices, using these vehicles as mobile sensors that eliminate the need for invasive infrastructure installation.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system creates a virtual representation of traffic conditions by collecting and processing position data from multiple vehicles. This digital copy of traffic flow information replaces the need for physical sensors embedded in the road infrastructure, achieving the same traffic monitoring function through data aggregation.

Inventive Principle:

Principle #26Copying

2Reliability

If conventional traffic control devices are installed using road excavation, then traffic control capability is provided, but traffic disruption and installation time increase

Engineering Contradiction:

Improvetraffic control capabilityVSAvoidinstallation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Vehicles serve as mobile intermediaries that carry wireless communication devices, eliminating the need for stationary infrastructure installation. The system leverages the existing movement of vehicles through the traffic control area to gather necessary data, requiring no road excavation or construction work.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

Vehicles equipped with wireless communication devices automatically provide their position information to the traffic control system without requiring any installation or configuration at the traffic control location. The vehicles themselves serve the function of traffic monitoring through their routine operation.

Inventive Principle:

Principle #25Self-service

3Reliability

If traffic control devices rely on fixed sensors under road surfaces, then continuous monitoring is achieved, but vulnerability to weather damage and functional loss increases

Engineering Contradiction:

Improvecontinuous monitoringVSAvoidweather damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system transitions from static, fixed sensors embedded in the road to dynamic, mobile vehicles that continuously move through the monitoring area. This dynamic approach allows the system to maintain continuous monitoring coverage while avoiding the weather-related damage that affects stationary underground infrastructure.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Vehicles act as mobile intermediaries that are not susceptible to road surface weathering, freezing, or water damage. By using vehicles already in operation as the monitoring platform, the system eliminates exposure to environmental factors that degrade fixed underground sensor installations.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Measurement precision

If conventional traffic control systems use extensive sensor networks, then accurate traffic data is obtained, but system cost and maintenance requirements increase

Engineering Contradiction:

Improvetraffic data accuracyVSAvoidsensor quantity

Core Design Contradiction:

Measurement precisionVSQuantity of substance

Solution Approach 1:

Vehicles with wireless communication devices perform multiple functions: their primary transportation role plus serving as mobile traffic monitoring sensors. This multi-functionality eliminates the need for dedicated sensor installations, reducing the total quantity of monitoring equipment while maintaining data collection capabilities across the entire traffic area.

Inventive Principle:

Principle #6Universality (Multi-functionality)
