Map-Based Speed Violation Alerts Using Location-Specific Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fleet operation management systems, such as Electronic Logging Devices (ELDs), are unable to effectively monitor and notify administrators of location-specific speeding violations, as they rely on global speed limits and may cause latency or resource management issues with real-time speed limit monitoring using image recognition or GPS.
Innovation Solution
A map-based notification system that accesses base-maps with location-specific speed limits and traffic rules, compares vehicle speed data to these limits, and generates notifications for speeding or rolling stop violations, providing in-cab and external alerts via visual, auditory, or SMS notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If global speed limits are used for monitoring, then the system is simple to implement, but it cannot detect location-specific speeding violations
Solution Approach 1:
The patent applies local quality by transitioning from a uniform global speed limit approach to location-specific speed limits. The system divides the monitoring area into different geographic zones, each with its own speed limit parameters stored in a database. The ELD device determines the vehicle's current location and retrieves the appropriate speed limit for that specific location, enabling precise detection of speeding violations tailored to local conditions.
2Measurement precision
If image recognition or GPS is used for real-time speed limit monitoring, then location-specific detection is improved, but latency and resource management issues occur
Solution Approach 1:
The patent applies preliminary action by pre-loading speed limit data for upcoming routes into the ELD device's memory before the vehicle reaches those locations. The system receives route information, identifies geographic zones along the route, and retrieves corresponding speed limit parameters in advance. This preparation eliminates the need for real-time image recognition or continuous GPS queries during travel, reducing latency and resource consumption while maintaining accurate location-specific monitoring.

AI summary
A map-based notification system configured to perform operations that include: accessing a base-map that comprises a map-tile, the map-tile defining a speed limit of a location; receiving vehicle data that includes speed data; determining that the speed data from the vehicle data transgresses the speed limit associated with the location defined by the map-tile; and causing display of a notification in response to determining that the speed data from the vehicle data transgresses the speed limit associated with the location defined by the map-tile.
