In order to deal with the significant variation of the relationship between the supply and demand of the signalized intersection,the method to allocate a dynamic lane-use was discussed.Based on the analysis of the optimization objective,optimization variables and the optimization model,a dynamic lane assignment optimal method was proposed based on the approach-group concept.The method was formulated as an integer-non-linear-programming model.To minimize the sum of the critical flow ratio was the most important design objective.The accuracy and the computation time of the method were tested by numerical examples.Results show thatthe approach-group concept can reduce the number of control variables significantly without reducing the accuracy of the optimization results and the proposed model can achieve the goal of real-time dynamic lane assignment control.
