The Study on Right-Turn Vehicle Capacity under Mixed Traffic Flow Conditions

Traffic conflicts exist among mixed traffic conditions. Considering influences of pedestrians, bicycles and mixed traffic flows, this paper first summarized the right-turn capacity calculation methods based on conflict analysis by applying the gap theory. Furthermore, the key of this paper is the right-turn capacity calculation formula based on statistical analysis (i.e., the vehicle capacity is presented as a curve with the capacity as the vertical axis and the pedestrian or bicycle flow as the horizontal axis) which is fitted using traffic survey data of six typical intersections in Beijing. Comparing the above two methods upon influences from pedestrians, bicycles and mixed traffic flows, the characteristics of right-turn capacity in different situations could be acquired. By comparing the queue length obtained from inputting right-turn capacity calculation data from this paper with that from existing methods, the results of this paper were closer to the practical situation and more accurate because the calculation formula of this paper not only applied the gap theory, but also adequately took the influence of pedestrians, bicycles and mixed traffic flows into account.
