For the effective use and management of urban traffic control systems, it is necessary to collect and process traffic data and produce traffic information. Average travel speed is typically used for classifying traffic conditions of traffic signalized intersection networks. The purpose of this paper is to solve the pitfall caused by the usage of average travel speed estimated by conventional technique for the signalized intersection networks. To do this, this paper has suggested the basis of criteria for selecting the speed data to be used for final estimation of travel speed. The key point is to check the relevancy of travel time of the vehicles traveled during the same evaluation time period.
