With the prevailing signal control technique in Japan, a time lag in control is unavoidable due to the time interval required for control data collection. To eliminate this time interval, various schemes have been devised, but as a signal control technique that can meet traffic demands in real time, the prevailing control technique still has room for further improvements or more sophistication. So, the Hokkaido Prefectural Police HQ developed a new control technique which determines control parameters by predicting the arriving states of vehicles at individual intersections based on traffic volume data collected at intervals of several seconds. This paper introduces this new control technique experimented and proved to be effective by the Police HQ. For the covering abstract see ITRD E114174.
