In this paper, we propose a website to exhibit the traffic information for every 5 minutes at certain places of street measured by three radio frequency identification (RFID) readers for 125 tags installed on two different urban-bus companies and transmit those information via GPRS modem from testing point to control center. Each data can be used to indicate the exact point of traffic condition in a big city. The result is very valuable for the local government to make a decision on the adjustment of urban-bus for their future use. The result shows that the application of RFID tag and reader is an alternative way to extract the traffic information instead of traditional loop detector. It is suggested that the vehicle speed estimated by 2 tags from RFID reader is more accurate than that of by 1 tag compared with historical data.
