Abstract
Methods and systems are disclosed for monitoring vehicular traffic congestion through the use of inter-vehicle communication and traffic chain counters. Data packets including counter, vehicle identification, direction, location, and speed information are transmitted between vehicles via short-range wireless communications. A receiving vehicle edits a data packet if the data packet reflects that the receiving vehicle has not yet edited the packet and is traveling in substantially the same direction as the vehicle which transmitted the packet to the receiving vehicle. If a receiving vehicle is the last vehicle to edit a packet, the receiving vehicle transmits a reporting packet to a traffic monitoring server via long-range wireless communications.
