Targeted Roadway Alert Transmission via Cellular Polygon Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current traffic management systems rely on broadcast methods with limited geographic targeting, resulting in reactive and inefficient communication of environmental information, particularly in determining and transmitting impact areas for roadway incidents, which can lead to delayed alerts and increased latency.
Innovation Solution
A system that utilizes highly accurate maps and real-time analytics to generate a continuously updated geographic polygon representing the impact area of an incident, allowing for targeted transmission of alerts through cellular infrastructure, independent of wireless networks, using a combination of collection devices, a network, and a location cloud to process and redistribute event data for relevant traffic participants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If broadcast methods with limited geographic targeting are used, then communication coverage is provided, but alert transmission latency increases and precision of impact area delivery deteriorates
Solution Approach 1:
The system segments the geographic area into specific impact zones defined by polygon coordinates rather than broadcasting to entire cellular coverage areas. This segmentation allows alerts to be transmitted only to devices within the precise impact area, improving both precision and reducing unnecessary network traffic that contributes to latency.
Solution Approach 2:
The system performs preliminary determination of impact area coordinates and affected cellular networks before alert transmission. By pre-calculating the geographic polygon and identifying which cellular networks overlap with this polygon, the system prepares transmission targets in advance, reducing actual alert transmission latency.
2Measurement precision
If cellular infrastructure is used for alert transmission, then targeted delivery to impact area is improved, but network overload may occur during high incident volume
Solution Approach 1:
The system applies local quality by transmitting alerts only to specific cellular networks that overlap with the impact area polygon, rather than broadcasting to all networks. This localized approach maintains high targeted delivery precision while minimizing the number of networks affected, thereby reducing the risk of network overload during high incident volume periods.
3Measurement precision
If geographic polygon with continuously updated parameters is generated, then impact area precision is improved, but system complexity increases
Solution Approach 1:
The system implements dynamics by using a geographic polygon with continuously updated parameters that reflect changing impact conditions. The polygon coordinates and affected cellular networks are dynamically determined based on real-time incident data, maintaining high impact area precision while using automated algorithms to manage the complexity of continuous updates.

AI summary
A method and apparatus for transmission of targeted roadway alerts. A server receives a first description of an incident. The server determines an impact area of the incident based on the description. The server generates a geographic polygon based on the impact are of the incident. The server overlays the geographic polygon on a first cellular map and transmits an alert message to one or more devices located within a cell of the first cellular map that contains at least a portion of the geographic polygon.
