Application and Evaluation of Traffic Signal Control Algorithm based on Travel Time Information

抄録

This study contained to develop a real-time signal control algorithm based on the sectional travel time and confirmed the reduction and equalization of delay by approach which was the objective function of the algorithm as against TOD control by the field test. The dissolved time of queue was calculated, using the average delay and detection time of probe vehicles, which was collected during the accumulated cycle. Then a delay variation and a targeted red time were calculated, and a phase assignment was conducted. This study was conducted to develop a real-time traffic signal control algorithm based on sectional travel time of individual vehicles, using general-purpose traffic information detectors. With the current of disseminating ubiquitous technology, the aim of this study was a fundamental change of traffic signal control method.
