To adapt the time-varying traffic at the intersection, the concept of a variable lane is proposed, which allows the dynamic change of the lane function to make full use of the spatial resource of the intersection. In this paper, an integrated model is developed to optimize lane use and signal timings for isolated signalized intersections with variable lanes. Aiming to minimize the intersection delay, the proposed binary-mixed integer nonlinear model can optimally allocate the time-space resources of an intersection. To illustrate the application of the model, an example is designed and analyzed. Compared to just optimizing the signal timings, the proposed method yields better results in terms of minimizing the intersection delay. The variable lane will influence the average delay per vehicle on different approaches and for different lane groups to varying degrees. The maximum degree of saturation in the model may affect the model results and should be carefully set.
