Road Damage Detection via Mobile Sensor Data Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for reporting and addressing road conditions and damage are inefficient, as they rely on manual reporting by drivers, which can be inaccurate and time-consuming, especially in large metropolitan areas, leading to delayed identification and repair of hazardous road issues.
Innovation Solution
A system and method that utilizes mobile devices equipped with sensors to detect road anomalies and report them to a central database, where the data is compared to previous reports and prioritized for maintenance, allowing for efficient allocation of repair resources based on severity and location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual reporting by drivers is used to report road conditions, then the system is simple to implement, but the accuracy and timeliness of road damage detection deteriorates
Solution Approach 1:
The patent replaces manual visual inspection and subjective driver reporting with automated sensor-based detection systems. Mobile devices equipped with sensors (accelerometers, gyroscopes, cameras) automatically detect and report road anomalies, eliminating human error and subjectivity while maintaining system simplicity through widespread mobile device deployment.
Solution Approach 2:
The patent introduces a centralized server as an intermediary that collects, processes, and validates reports from multiple mobile devices. This intermediary analyzes sensor data, compares reports across multiple sources, and determines road damage severity, thereby improving detection accuracy while keeping individual mobile device functions simple.
2Device complexity
If manual reporting by drivers is used, then the system complexity is low, but the time required to identify and locate road damage increases
Solution Approach 1:
The patent enables continuous road monitoring by having mobile devices constantly collect and transmit sensor data as vehicles travel. This continuous data stream allows for real-time detection of road anomalies, eliminating the intermittent and delayed nature of manual reporting systems while maintaining manageable complexity through automated processing.
Solution Approach 2:
The patent implements a feedback mechanism where the centralized server analyzes incoming reports, identifies patterns, and prioritizes road damage locations. This automated feedback loop rapidly processes multiple reports, compares them against historical data, and quickly identifies confirmed road damage, significantly reducing the time to locate and address problems.
3Productivity
If driver reports are used without verification, then the reporting process is quick, but the reliability of road damage information deteriorates
Solution Approach 1:
The patent merges multiple independent reports from different mobile devices to verify road damage. When multiple sensors detect similar anomalies at the same location, the system consolidates this data to confirm road damage, thereby maintaining quick reporting while significantly improving reliability through cross-validation.
Solution Approach 2:
The patent applies partial verification by requiring a threshold number of corroborating reports before confirming road damage. This approach processes reports quickly by not requiring exhaustive verification of each individual report, while still ensuring reliability through multiple independent confirmations of the same anomaly.
Data Source
AI summary
Methods and systems for distributed detection of road conditions and damage are described. In one embodiment, a method for distributed detection of road conditions and damage is provided. The method includes receiving, from one or more mobile devices, a plurality of reports of anomalies associated with roads in a geographic area. The method also includes storing the received reports of anomalies in a database and comparing each report of an anomaly to stored reports of previous anomalies in the database. The method further includes determining whether each report of an anomaly indicates road damage or a temporary problem. The method includes generating a prioritized list of locations of anomalies associated with one or more roads that have been determined to have road damage that needs maintenance and/or repair.
