Graph-based Modeling of Information Flow Propagation under Vehicle-to-Vehicle Communications

A vehicle equipped with a vehicle-to-vehicle (V2V) communica-tions capability can continuously update its knowledge using its own experience and anonymously obtained travel experience data from other such equipped vehicles. 

In a V2V communications based traffic system, the dynamics of traffic flow and inter-vehicle communication lead to the dyna-mics of information flow propagation. 

In this context, this study proposes a graph-based multi-layer network framework to represent the V2V communications based traffic system as a complex system which is comprised of three coupled network layers: a physical traffic flow network, and virtual inter-vehicle communication and information flow networks. 

The potential benefits of the proposed graph-based modeling of the information flow propagation are illustrated by the ability to identify vehicle knowledge in time and space using a simple graph-based reverse search algorithm and the storage of the information flow network as a single graph database.
