Preventing Traffic Over-Reporting via Misleading Probe Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Navigation and mapping service providers face challenges in suppressing misleading traffic incident reports, as existing systems struggle to differentiate between genuine traffic congestion and manipulated data, leading to over-reporting of traffic incidents.
Innovation Solution
A computer-implemented method and apparatus that detect connection attempts between wireless communication infrastructure devices and probe devices, process wireless signals to determine height data, and identify if multiple probe devices are carried by a single entity, thereby adjusting traffic reports to prevent over-reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple probe devices are used to collect traffic data, then data coverage and reporting frequency are improved, but false traffic reports increase due to manipulated data from single entities carrying multiple devices
Solution Approach 1:
The system changes the parameter of probe device height by comparing it against expected height ranges for legitimate vehicles. By processing wireless signals to determine actual height data and comparing it with known height data of infrastructure devices, the system identifies probe devices that are abnormally positioned (e.g., carried in backpacks or on bicycles) and excludes them from traffic reporting, thereby maintaining data coverage while improving report accuracy
Solution Approach 2:
The system introduces wireless signal processing as an intermediary mechanism to verify the legitimacy of probe devices. By using wireless communication infrastructure devices as reference points and processing signals between them and probe devices, the system creates a verification layer that distinguishes between legitimate traffic participants and manipulative single-entity deployments without reducing data collection capacity
2Quantity of substance
If existing systems accept all probe data, then traffic reporting coverage is maximized, but misleading data from manipulated probe devices causes over-reporting of traffic incidents
Solution Approach 1:
The system performs preliminary verification of probe device legitimacy before accepting their data for traffic reporting. By proactively determining height data of probe devices and comparing it with expected ranges, the system pre-filters out manipulative devices from the data pool, ensuring that only legitimate probe data contributes to traffic incident detection while maintaining comprehensive coverage from valid sources
Solution Approach 2:
The system applies parameter-based filtering by changing the acceptance criterion from simply accepting all probe data to accepting only data from devices within expected height parameters. This parameter change enables the system to maintain high data volume from legitimate sources while automatically excluding manipulative devices, thus improving measurement precision without reducing overall data quantity

AI summary
An approach is provided for preventing traffic over-reporting via identifying misleading traffic data. The approach involves, for example, detecting a connection attempt between a wireless communication infrastructure device and a plurality of probe devices. The wireless communication infrastructure device is associated with a known height. The approach also involves processing one or more wireless signals associated with the connection attempt to determine height data of the plurality of probe devices. The approach further involves determining based on the height data that at least two of the plurality of probe devices are carried by a single entity. The approach further involves providing data indicating the at least two of the plurality of probe devices as an output.
