Roadside Infrastructure Localization Under Snow and Obstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to precisely locate and monitor roadside infrastructure assets, such as fire hydrants, due to obstructions like snow, ice, leaves, or vehicles, which can delay emergency responders and violate regulatory clearances, potentially increasing fire damage and incurring fines.
Innovation Solution
A vehicle-mounted UWB radar and optical camera system detects infrastructure assets and assesses obstruction severity, providing alerts and navigation assistance to ensure clear access, using templates, geofencing, and predictive algorithms for obstruction management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If snow or other obstructions accumulate around fire hydrants, then accessibility for emergency responders is blocked, but clearing operations require precise location detection which is difficult under obstruction
Solution Approach 1:
The system performs preliminary detection of infrastructure asset locations using radar and camera systems before snow or obstructions accumulate. The detected locations are stored in a database with geofencing parameters, enabling rapid retrieval and alert generation when obstructions are later detected without requiring real-time precise location determination
Solution Approach 2:
The patent introduces an intermediary processing system that combines radar transceiver data with optical camera imagery. The radar provides initial location detection while the camera captures visual confirmation, and the controller integrates both data sources to accurately determine asset locations even when partially obscured by snow or other obstructions
2Loss of time
If emergency responders manually locate infrastructure assets during emergencies, then response time is delayed, but automated systems increase device complexity
Solution Approach 1:
The system employs a multi-functional vehicle-mounted platform that combines radar transceiver, optical camera, GPS location tracking, and database management capabilities. This single integrated system performs detection, location verification, geofencing, and alert generation functions that would otherwise require multiple separate systems, reducing overall complexity while enabling automated response time reduction
Solution Approach 2:
The automated system performs self-service by automatically detecting infrastructure assets, determining their locations, comparing them against regulatory clearance requirements, and generating alerts to appropriate authorities without human intervention. The vehicle's own sensors and processing systems enable it to independently complete the monitoring and notification function
3Manufacturing precision
If regulatory clearance requirements are monitored manually, then compliance accuracy decreases, but automated monitoring increases system complexity
Solution Approach 1:
The system pre-loads regulatory clearance requirements into the controller's database along with infrastructure asset templates. When an asset is detected, the system automatically retrieves the applicable clearance standards and performs compliance assessment by comparing the detected asset location and surrounding environment against these predetermined requirements, ensuring accurate compliance evaluation
Solution Approach 2:
The system provides feedback by generating automated alerts when compliance violations are detected. The controller analyzes the spatial relationship between detected assets and surrounding obstructions, compares this against regulatory clearance requirements, and sends notifications to appropriate authorities when clearance is insufficient, creating a closed-loop compliance monitoring system

Implementation Method 1
a surface penetrating radar transceiver configured to interrogate a region adjacent a pathway of the vehicle
Data Source
AI summary
Surface penetrating radar interrogates a region adjacent a pathway of the vehicle in response to activation by a user. An object detection system which is responsive to the radar transceiver is configured to recognize one or more spatial signatures of one or more detected objects in the region. A controller coupled to the radar transceiver and the object detection system is configured to (i) compare a respective spatial signature of at least one of the detected objects to a plurality of predetermined target signatures to detect an infrastructure asset, (ii) assess a perimeter around the detected infrastructure asset to estimate a severity of an obstruction blocking the infrastructure asset, and (iii) convey an alert message to the user when the estimated severity is greater than a threshold.
