Emergency Vehicle Notification System with Acknowledgement Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Emergency service vehicles face challenges in ensuring that all entities within their vicinity, including pedestrians and other vehicles, are aware of their presence and status, especially during emergency operations, due to varying awareness levels and communication limitations among entities.
Innovation Solution
A method and system that enables emergency service vehicles to transmit notifications of their presence to surrounding entities, obtain acknowledgments, and present information about non-responsive entities to the operator, using wireless communication networks and awareness levels defined by sensing capabilities, allowing for two-way communication when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If emergency service vehicles transmit notifications to multiple entities, then situational awareness is improved, but communication reliability deteriorates due to varying awareness levels among entities
Solution Approach 1:
The system implements a feedback mechanism where entities receive notifications from the emergency service vehicle and send back acknowledgments. The vehicle's device receives these acknowledgments and determines which entities have confirmed awareness. This closed-loop feedback system allows the vehicle operator to know the current awareness status of surrounding entities, improving situational awareness while maintaining communication reliability through verification.
2Reliability
If the system monitors acknowledgments from all entities, then safety is improved, but device complexity increases
Solution Approach 1:
The vehicle's device performs multiple functions: it transmits notifications to entities, receives acknowledgments from entities, determines awareness status based on acknowledgments, and presents information to the operator. By consolidating these functions into a single multi-functional device, the system achieves comprehensive safety monitoring without proportionally increasing overall system complexity.
3Reliability
If the system presents information about non-responsive entities, then operational safety is improved, but information processing complexity increases
Solution Approach 1:
The system extracts and identifies specifically those entities that have not sent acknowledgments (non-responsive entities) and separates this information for presentation to the operator. By extracting only the critical information about non-responsive entities rather than processing and displaying all entity data, the system improves operational safety through targeted information presentation while minimizing information processing complexity.

AI summary
A processing system including at least one processor may transmit a notification of a presence of an emergency service vehicle to a plurality of entities, obtain, from at least a first entity of the plurality of entities, at least a first acknowledgement of the presence of the emergency service vehicle, determine that at least a second acknowledgement is not obtained from at least a second entity of the plurality of entities, and present information associated with the at least the second entity to a device of the emergency service vehicle.
