Exploration of Potential Capacity of Right-Turn Movement at Signalized Intersections Under Mixed Traffic Conditions

China is a country where bicycles are commonly used in urban travel. There are no conflicts on the link of the roadways between bicycle traffic and vehicular traffic because a side median is used to separate these two flows. However, there are heavy conflicts between bicycle traffic and vehicular traffic at intersections. Due to the layout of carriageway for vehicles and bicycles, the right turn vehicles will conflict with through bicycles at intersections. The objective of this study is to explore the potential capacity of right turn movement at signalized intersections under mixed traffic condition. A new concept of a bike grouping was introduced in this study. The critical gaps and follow-up times of right turn movement traversing bicycle fleets were analyzed using Logit model. Thus, a bike-grouping based model was developed to estimate the potential capacity of right turn movement under the green indication. The model was calibrated using the collected data from 8 signalized intersections of Beijing. This model is very useful for the estimation of capacity under mixed traffic conditions, which is a unique feature of transportation network in China.
