Work Zone Tracking System for Automated Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack real-time and comprehensive tracking of work zones, leading to safety hazards and inefficiencies in traffic management, particularly for short-term road construction projects, where information dissemination is limited and manual inspections are often inadequate.
Innovation Solution
The Statewide Work Zone Information System (SWIS) utilizes asset tracking devices to provide real-time location data of traffic control devices, automating the inspection process by determining if work zones comply with regulations, and integrating this information into a centralized server for user interfaces and navigation systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual inspection methods are used to ensure work zone compliance, then regulatory oversight is maintained, but inspection efficiency and real-time monitoring capability deteriorate
Solution Approach 1:
The work zone inspection system performs self-monitoring and self-reporting through automated asset tracking devices that continuously report their locations and statuses to the central server, eliminating the need for manual inspection while maintaining regulatory oversight
Solution Approach 2:
The patent replaces manual mechanical inspection processes with an automated electronic system using GPS tracking devices, wireless communication, and computer processing to monitor work zone compliance in real-time
2Reliability
If real-time tracking of traffic control devices is implemented, then safety and regulatory compliance improve, but system complexity and initial costs increase
Solution Approach 1:
The asset tracking devices perform multiple functions including GPS location tracking, work zone boundary definition, regulatory compliance verification, and real-time status monitoring, reducing the need for separate specialized systems
Solution Approach 2:
The patent introduces a centralized server as an intermediary that receives data from multiple asset tracking devices, processes the information, and generates compliance reports, simplifying the overall system architecture
3Loss of information
If comprehensive tracking of all work zone assets is implemented, then information completeness improves, but data processing requirements and system resource needs increase
Solution Approach 1:
The asset tracking devices transmit location and status data periodically rather than continuously, reducing energy consumption while maintaining real-time awareness of work zone positions and compliance status
Solution Approach 2:
The system extracts and processes only the essential information needed for compliance verification from the data collected by tracking devices, reducing processing requirements while maintaining information completeness
Data Source
AI summary
A computer system includes a memory and a processor. The processor executes instructions to perform steps that include receiving a message from an asset tracking device, the message comprising position information for the asset tracking device and a traffic control device type for a traffic control device that the asset tracking device is attached to. The processor uses the received message to determine a road that the traffic control device is positioned on and a location of the traffic control device along the road.
