Based on the phase conflict matrix and safety principle, a phase design optimization model is proposed to minimize the sum of flow-capacity ratios concerning critical phases. Both dynamic programming method and improved elite multi-population genetic algorithm are used to automatically generate the optimal phase design scheme. Finally, the model and its algorithm are verified by a numerical example, which shows this optimization model can reduce the total flow-capacity ratio of critical phases by 6.5%, compared with the current phase design.
