This paper presents a general signal control model for roundabout intersections. By studying the characteristics of signal control and vehicle movements occurring at roundabout intersections, the wave theory, along with the HCM2000 delay function, is employed to analyze the features of each part of the vehicle delay, respectively. By setting the objective function and constraints on timing split and phase sequence, the paper proposes a theoretical optimal timing model for roundabout intersections based on the traditional dual ring control pattern. Finally, a case study was provided to illustrate the effect of the model with numerical results indicating that the proposed optimal timing model is capable to produce satisfying timing splits.
