Abstract
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.
