1. A method for managing vehicles on a road network, the method comprising: accessing a matrix of vehicle performance parameters of a plurality of communicating vehicles on the road network; representing the plurality of communicating vehicles in a graph with a plurality of nodes corresponding to the plurality of communicating vehicles and edges corresponding to the vehicle performance parameters; partitioning, with a processing device, the graph to reduce disruptions to the road network below a threshold level to support safe and efficient traffic flow; assigning one or more exclusion zones within the road network to each partition of the graph by associating the vehicle performance parameters for each vehicle; establishing, based on analysis of the vehicle performance parameters of the plurality of communicating vehicles, a set of security requirements for additional vehicles to join the plurality of communicating vehicles on the road network; identifying geographical boundaries of the road network; establishing a policy prohibiting vehicles that are unable to pass the set of security requirements from entering the geographical boundaries of the road network; and wirelessly communicating, with a processing device, between a central computing facility and at least one of the plurality of communicating vehicles to enforce the one or more exclusion zones.
