Abstract

This study develops the framework of a temporary signal control system using the traffic counts from movable vehicle detectors and the vehicle trajectory data from probe vehicles equipped with GPS. Also it includes not only the concept of minimizing the volume of total travel time but also CO 2 emission. In order to achieve effective signal control, signal parameters should be determined in accordance with traffic flows. However, monitoring systems, which are installed on roads as a fixed infrastructure, is usually not installed for temporary use. Therefore, after a method of estimating the volume of CO 2 emission is proposed, this study develops a framework of signal control system with movable monitoring tools and validates the movable detectors by checking the accuracy of their counts. Through the validation, we confirm that the accuracy of the observed traffic volume is fairly good but the estimated saturation flow rate has the tendency of over-estimation.
