摘要
讨论了单个交叉口定时控制的周期和绿信比优化模型,并且在一般条件下满足交叉口控制条件的约束,提出应用遗传算法解出该非线性模型的最优解或近似最优解,并结合实际交叉口控制案例对模型和算法进行了验证,结果表明模型和算法具有适用性。
First, this paper made an analysis of the cycle and split optimization model of pre-timed signals control at isolated intersections. In general, the restriction of the model met the conditions of intersection control. Then, a genetic algorithm was put forward to solve the nonlinear model that the optimal solution or the approximate optimal solution can be available. Finally, the model and algorithm were verified by the actual cases of intersection control, and the results show the applicability of the model and algorithm.
