Geofenced Traffic Alerts for Low-Data Vulnerable Road User Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for providing location-dependent traffic information to vulnerable road users generate excessive data volumes and require significant server capacity, even when the traffic situation is non-critical.
Innovation Solution
A method and system where mobile devices define a monitoring area, transmit location data only when within that area, and a server checks predefined conditions between devices for potential traffic situations, transmitting alerts only when necessary, using cellular connections and satellite positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If location data is transmitted continuously to servers over a large area, then comprehensive traffic monitoring is achieved, but data volume and server capacity requirements increase significantly
Solution Approach 1:
The patent applies local quality by defining specific monitoring areas (geofences) where location data transmission is activated. Instead of continuous transmission over large areas, the system selectively monitors only those geographic zones where vulnerable road users are present and potential conflicts may occur. This localized approach maintains comprehensive monitoring coverage in critical areas while significantly reducing overall data volume transmitted to servers.
Solution Approach 2:
The patent segments the monitoring approach by dividing the service area into discrete geofenced zones. Each geofence represents a distinct monitoring unit with its own activation conditions. This segmentation allows the system to manage data transmission in manageable chunks rather than as a continuous large-scale operation, reducing server load and data processing requirements while maintaining effective coverage.
2Reliability
If location data is transmitted continuously to servers over a large area, then comprehensive traffic monitoring is achieved, but server capacity requirements increase significantly
Solution Approach 1:
By implementing location-dependent activation where servers only process data from devices within defined geofenced monitoring areas, the system reduces server capacity requirements. Servers receive and process information only when devices are present in specific zones of interest, rather than continuously processing data from all devices across large areas. This localized processing approach maintains comprehensive monitoring coverage while significantly reducing computational power and server resources required.
3Loss of information
If all location data is processed by the server, then complete traffic situation analysis is achieved, but unnecessary data processing occurs in non-critical situations
Solution Approach 1:
The patent implements preliminary action by pre-defining geofenced monitoring areas and activation conditions before data transmission occurs. The system establishes geographic boundaries and conflict criteria in advance, so that location data is only transmitted and processed when devices enter these predefined zones and meet specified conditions. This preliminary setup prevents unnecessary data processing in non-critical situations while ensuring complete analysis when actual traffic conflicts are detected within monitoring areas.
4Reliability
If monitoring covers large areas continuously, then all potential traffic conflicts are detected, but data transmission volume increases excessively
Solution Approach 1:
The patent applies local quality by creating discrete geofenced monitoring areas where conflict detection is activated. Instead of continuous monitoring across large geographic regions, the system concentrates monitoring resources within specific bounded zones where vulnerable road users are present. This approach ensures all potential traffic conflicts within these localized areas are detected while minimizing data transmission volume by excluding areas outside the geofences from continuous monitoring.
