In this paper, a traffic data exchange protocol (TDXP) will be introduced. TDXP is an application layer data exchange protocol for the pull-mode and push-mode communication from vehicle to vehicle or from vehicle to roadside infrastructure. In TDXP, real-time traffic data are generated by a group of relevant vehicles and organized by the leader of this group. A group of vehicles, not an individual vehicle, is applied as basic communication unit. The communication mode based on vehicle group also provides a promising method for real-time traffic data collection for intelligent transportation system. At the same time, TDXP as a stateless and lightweight protocol, it can be easily deployed in vehicles that are equipped with basic communication and computing components.
