Abstract
In one aspect, an exemplary method for sharing traffic data among a plurality of vehicles includes: a first vehicle receiving current traffic data from at least a second vehicle over a first network protocol; the first vehicle transmitting current traffic data from the first vehicle and the current traffic data received from at least the second vehicle to a roadside unit over a second network protocol; the first vehicle receiving processed traffic data from the roadside unit over the second network protocol, the processed traffic data being based on the current traffic data received from the first vehicle and from at least the second vehicle; and the first vehicle transmitting the processed traffic data received from the roadside unit to at least the second vehicle over the first network protocol.
