Solution Overview
Problem
Maintaining road safety and efficiency is challenging due to unpredictable weather conditions, microclimates, and limited resources, making it difficult to effectively manage treatments such as snow removal and ice control across multiple roads.
Innovation Solution
A road maintenance analytics system that collects data from various sources, including vehicle-mounted sensors and network services, analyzes road conditions and weather, and uses artificial neural networks to optimize treatment recommendations, including type, distribution rate, and route planning for service equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual road condition assessment and treatment decision-making is used, then operational flexibility is maintained, but response time and treatment efficiency deteriorate
Solution Approach 1:
The system enables self-service through automated road condition monitoring using sensors embedded in the pavement structure, automatic data transmission to central servers, and algorithm-based treatment recommendations that operate without continuous human intervention, thereby improving efficiency while maintaining operational flexibility
Solution Approach 2:
Manual visual inspection and subjective treatment decision-making are replaced with automated sensor-based monitoring systems and computer algorithm analysis, substituting mechanical human operations with electronic detection and computational processing to reduce response time
2Measurement precision
If extensive sensor networks and data collection systems are deployed, then measurement precision improves, but device complexity increases
Solution Approach 1:
The sensor network is designed with multi-functionality where single sensor units perform multiple detection tasks (temperature, strain, moisture, ice detection), and the central server handles diverse functions including data reception, analysis, treatment recommendation generation, and equipment control, reducing overall system complexity while maintaining high measurement precision
Solution Approach 2:
The system is segmented into modular components: distributed sensor units embedded in road sections, centralized server for data processing, and separate control systems for treatment equipment. This segmentation allows each component to be optimized independently while maintaining overall system precision without excessive complexity
3Reliability
If real-time data collection and analysis is implemented, then treatment recommendation accuracy improves, but energy consumption increases
Solution Approach 1:
The system implements periodic data collection and analysis cycles rather than continuous operation. Sensors transmit data at intervals based on detected changes or predetermined schedules, and the server performs batch processing of accumulated data, maintaining high recommendation accuracy while significantly reducing energy consumption compared to continuous real-time processing
Data Source
AI summary
Road maintenance activities are subject to data analytics. Data regarding a road can be received from a variety of sources including vehicle mounted sensors and network accessible services. A road treatment recommendation, such as plowing or treatment material distribution, can be automatically determined or inferred based on received data. The treatment recommendation can be conveyed to a service center or driver to facilitate road maintenance.
