摘要
基于遗传算法建立了高速公路OD反推模型,通过对OD矩阵进行修正和流量分配,将得到的路段分配流量与实测流量之差的最小值作为所求OD流量,仿真结果表明,该算法效果良好,精度较高,可以为高速公路的优化控制提供理论与工程帮助。
The paper establishes the OD matrix estimation along expressways based on genetic algorithm,concludes the minimal value of the balance between the distribution flow and the measured flow of the sections as the OD flow,and proves by the simulation results that the calculation has better effect,higher accuracy,so as to provide the theoretical and engienerign assistance for the optimization control of the expressways.
