Solution Overview

Problem

Current traffic monitoring and management systems are inadequate due to reliance on manual, inconsistent, and expensive methods such as infrared receivers, video image vehicle detection systems, and loop detectors, which are not reactive or precise enough to effectively manage traffic flow, reduce fuel consumption, and ensure safety and energy efficiency.

Innovation Solution

A system comprising remote sensor devices in vehicles, communication hubs along roadways, a central server, and a network interface that collects and analyzes traffic data to calculate optimal traffic flow and transmit adjustments to traffic lights, using RFID and GPS modules for real-time data collection and communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual monitoring methods (infrared receivers, video image systems, loop detectors) are used, then traffic monitoring can be implemented, but the systems are not reactive enough, require human monitoring, have high failure rates, and are too imprecise for sophisticated traffic flow management

Engineering Contradiction:
Improvetraffic detection precisionVSAvoidautomation level
Core Design Contradiction:
Measurement precisionVSExtent of automation

Solution Approach 1:

The system employs automated sensor devices in vehicles that self-monitor traffic conditions and transmit data without human intervention. The remote sensors automatically detect traffic parameters, the communication hubs autonomously relay information, and the central server independently processes data to generate traffic flow management decisions, creating a fully self-service automated monitoring system

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual visual observation methods with electronic sensor-based detection systems. Remote sensors in vehicles automatically capture traffic data, substituting human operators with automated detection devices. This mechanical-to-electronic substitution enables continuous, precise, and automated monitoring without human fatigue or inconsistency

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If existing traffic monitoring systems are deployed, then basic traffic detection is possible, but they cannot provide sophisticated management for vehicles, energy consumption readouts, or vehicular maintenance warnings

Engineering Contradiction:
Improvetraffic management capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system integrates multiple functions into a unified platform: traffic flow monitoring, energy consumption tracking, vehicle maintenance warning, and route optimization. The central server processes diverse data types from multiple sources and provides comprehensive traffic management capabilities, making the system versatile and multi-functional rather than specialized for单一 purpose

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system divides traffic management into separate functional modules: remote sensors for data collection, communication hubs for data transmission, central server for processing, and application layers for specific functions (traffic flow, energy monitoring, maintenance warnings). This segmentation allows each component to specialize while contributing to overall system versatility

Inventive Principle:
Principle #1Segmentation

3Productivity

If traditional traffic light timing is used, then traffic flow management is simple, but congestion, fuel consumption, and idling time cannot be effectively reduced

Engineering Contradiction:
Improvetraffic flow efficiencyVSAvoidfuel consumption
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The system dynamically adjusts traffic light timing based on real-time traffic conditions detected by remote sensors. Instead of fixed timing schedules, the traffic management system continuously monitors actual traffic flow and adapts signal timings to current conditions, enabling dynamic optimization of traffic flow efficiency and reduction of idle time

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements closed-loop feedback by monitoring traffic conditions, analyzing data at the central server, and automatically adjusting traffic light timings based on detected congestion levels. This feedback mechanism enables continuous optimization of traffic flow and energy efficiency by responding to actual road conditions rather than predetermined schedules

Inventive Principle:
Principle #23Feedback
