Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current traffic safety technologies face challenges in scaling across multiple participants and industries due to privacy concerns and reluctance to share location data, limiting their effectiveness in protecting vulnerable road users.
Innovation Solution
A 'connected safety' system that utilizes a location-based server with a vulnerable road user protocol, a hybrid simulation engine, and a risk assessment module, which anonymizes data and employs noise-cancelling headphone and 3D audio algorithms to provide alerts, ensuring interoperability and mitigating privacy concerns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If location data is shared among traffic participants to prevent collisions, then traffic safety is improved, but privacy concerns arise and information sharing is limited
Solution Approach 1:
The patent extracts and removes personally identifiable information (PII) such as vehicle identification numbers, license plate numbers, and driver information from the shared location data. Only anonymized data containing location coordinates, timestamp, and road user type is shared among participants, enabling safety functionality while eliminating privacy risks associated with PII transmission and storage.
Solution Approach 2:
The patent introduces an intermediary server that acts as a mediator between road users. This server receives location data from participants, performs anonymization by removing PII, and redistributes the cleaned data to other participants. The intermediary handles the privacy-sensitive processing centrally, allowing data sharing without direct exposure of personal information between participants.
2Reliability
If databases are used to store location data for traffic control, then collision prevention is enabled, but the system cannot scale openly across multiple industries and actors
Solution Approach 1:
The patent designs a universal protocol that can be implemented by any road user (vehicles, pedestrians, cyclists) and any service provider without requiring industry-specific databases or infrastructure. The anonymized location data format and communication protocol are standardized, allowing the system to scale across multiple industries and actors using existing networks and devices.
Solution Approach 2:
The patent enables road users to independently participate in the safety network by simply sharing their own anonymized location data and receiving alerts from others. No central authority or complex infrastructure is required for participation - each participant autonomously implements the protocol using their existing devices and networks, facilitating open scaling across industries.
3Reliability
If personalized alerts are provided to vulnerable road users, then alert effectiveness is improved, but data processing complexity increases
Solution Approach 1:
The patent applies different alert strategies based on the specific road user type and situation. Vulnerable road users receive enhanced alerts with additional information such as suggested evasive maneuvers, while other road users receive standard alerts. The risk assessment algorithm adjusts its analysis depth and alert granularity according to the vulnerability level and context, optimizing effectiveness without uniformly increasing complexity for all users.

AI summary
The present disclosure provides a set of tools that enable traffic safety developments across multiple participants and industries, with location and other safety related data being shared in an anonymized fashion. Specifically, a location based server is provided that implements a vulnerable road user protocol. This vulnerable road user protocol avoids the use of global vehicle identification numbers and does not utilize persistent storage for such information, thereby mitigating location based privacy concerns. Further, the present disclosure provides a “hybrid” simulation engine that can be used to tailor and provide specific road user alerts, and specifies a risk assessment module that acts as a logic for quantifying the risk level associated with each unique road user relationship. Finally, the present disclosure provides an alert methodology for certain vulnerable road users based on noise-cancelling headphone and 3D audio algorithm technologies.
