Field Experiment of Offline Traffic Signal Control using Probe Data Collected via Infrared Beacons

Recently application of probe data to traffic management has attracted attention of traffic researchers. The probe data enables traffic administrators to observe road traffic conditions of ordinary roads including local streets with no vehicle detector installed. This paper describes the possibility of making use of probe data for traffic signal control on a local road without vehicle detectors. The authors conduct a field experiment on a local route in the city of Yokohama to evaluate their previous simulation study. First the authors collect probe data by using passenger cars installed onboard units and estimate travel time using the probe data. Second, they calculate the traffic indexes by the estimated travel time every thirty minutes and classified them into nine traffic patterns. Moreover, they design new coordinated control parameters corresponding to each pattern. Finally they apply the new parameters to actual signal controllers and verify the effectiveness of the proposed method. The experimental results show that the revised signal control parameters can successfully lessen the queue length and carbon dioxide emissions. The authors conclude that probe data can be applied to offline signal control.
