We propose a system to estimate the traffic congestion distance using IEEE 802.15.4, that is extended by multicommunication frequency division multiplexing. Our proposed system is developed at 20% equipped rate, where five lanes are considered. Furthermore, in our proposed system, it is assumed that the equipped rate in all lanes increases. Our proposed method can estimate an error rate lower than 10% approximately at on equipped rate greater than 50%. Additionally, we use 16 terminals in the actual environment. From the actual experiment, we find that our proposed method involving the use of communication pattern 2 is 300% faster than the existing method. © 2012 Institute of Electrical Engineers of Japan.
