Geospatial Emergency Broadcast Radius Algorithm
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency communication systems often fail to effectively alert nearby individuals who can provide immediate assistance during emergencies, as messages sent through mobile devices may reach irrelevant recipients and do not efficiently inform capable neighbors in close proximity.
Innovation Solution
A method and system for emergency broadcast data generation and publication in a constrained geospatial vicinity, using a processor and memory to validate and publish emergency data from a mobile device, ensuring it reaches verified users within a threshold radial distance, with features like geospatial validation, radial distribution, and push notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If emergency messages are sent through mobile devices using traditional social media platforms, then the messages can reach a large number of recipients, but the messages reach irrelevant recipients who are not nearby and may miss the important message
Solution Approach 1:
The system applies local quality by geographically segmenting the recipient population and delivering emergency messages only to users within a specific radius of the emergency location. This ensures that message relevance is maintained by targeting only nearby recipients who can actually respond to or assist with the emergency situation.
Solution Approach 2:
The system segments the broad recipient base into geographically defined groups using radial distance calculations from the emergency location. By dividing the potential recipient population into relevant (within radius) and irrelevant (outside radius) segments, the system eliminates information loss to irrelevant recipients while maintaining comprehensive coverage of all nearby potential responders.
2Speed
If emergency messages are broadcast to all users, then the speed of notification is maximized, but the efficiency of reaching capable neighbors in close proximity is reduced
Solution Approach 1:
The system performs preliminary action by pre-establishing user location data and emergency contact information in the database before emergencies occur. When an emergency message is received, the system immediately calculates radial distances and identifies eligible recipients without delay, enabling fast targeted notification rather than slow broad broadcasting followed by filtering.
Solution Approach 2:
The system introduces a geographic radius calculation as an intermediary mechanism between the emergency message and the recipient population. This intermediary filters and directs messages efficiently to capable neighbors within the specified radius, maintaining notification speed while maximizing productivity by ensuring every recipient is a potential responder.
3Reliability
If traditional emergency services are called, then professional help is provided, but the response time may be delayed due to distance from the emergency location
Solution Approach 1:
The system performs preliminary action by pre-collecting and storing location data, emergency contacts, and user capabilities in the database before emergencies occur. This preparation enables immediate identification and notification of the nearest capable responders when an emergency happens, reducing response time while maintaining reliability through verified user information.
Solution Approach 2:
The system enables self-service by allowing users to pre-register their emergency contacts, medical information, and response capabilities. During an emergency, nearby users can autonomously respond without requiring dispatcher intervention, reducing response time while maintaining reliability through pre-verified user profiles and capabilities.
4Loss of information
If neighbors are contacted one-at-a-time, then the message reaches relevant recipients, but critical time is wasted in the contact process
Solution Approach 1:
The system merges individual neighbor contact processes into a single automated batch operation. By combining multiple recipient notifications into one simultaneous broadcast to all users within the radial distance, the system achieves both message delivery accuracy (targeting only relevant nearby neighbors) and time efficiency (notifying all neighbors simultaneously rather than sequentially).
Data Source
AI summary
Disclosed are a method, a device and a system of emergency including crime broadcast data generation and publication in a constrained geospatial vicinity around a broadcast location of a neighborhood social network. In one embodiment, the emergency broadcast data is radially distributed as a notification data through an on-page posting, an electronic communication, and/or a push notification delivered to (1) a set of recipients through an internet protocol (IP) based network associated with users and/or their user profiles around an epicenter defined at a set of geospatial coordinates associated with the emergency broadcast data generated through a computing device or (2) a set of service providers through a cellular network using the radial algorithm in addition to the set of recipients through the IP based network associated with users and/or their user profiles.
