This paper attempts to explore the potential capacity of right turn movement when there are conflicts between right turn vehicles, pedestrians, and bicycles at signalized intersections. In order to take this impact into account in the capacity estimation, it is necessary to assume that all pedestrians and bicycles observe the traffic regulation, which means pedestrians cross intersections only when the pedestrian's signal indication is on. The objective of this study is to quantitatively analyze pedestrians' and bicycles' impacts on the capacity of right-turn vehicle at signalized intersections. New concepts of "pedestrian group" and "equivalent factor of bicycle versus pedestrian (PBF)"were introduced in this paper. The PBF was computed and its value is 1.7. With these concepts, a pedestrian-grouping based model was developed to estimate the potential capacity of right turn movement under green indication. The model was calibrated using the collected data from eight signalized intersections of Beijing and proved robust after hypothetic test.
