摘要
为了提高公路选线的效率和选线质量,最终实现智能选线,本文从控制公路路线质量的技术、经济及安全性指标出发,建立路线优化数学模型,以MATLAB为实验平台,基于遗传算法适应度函数和遗传操作编程,通过参数设定,最终实现公路选线方案的自动寻优.选线实例表明,基于遗传算法的公路智能选线方法,可在选线区域自动随机搜索公路路线交点,并自动完成公路路线优化,得到最佳公路路线方案.结果证明,将遗传算法应用到公路自动选线中可在一定程度上实现公路路线方案的自动寻优,提高公路选线效率和选线质量.
For improving the efficiency and quality of highway route selection and finally realizing intelligent route selection,this paper establishes a mathematical model of route optimization based on the technical,economic and safety indexes of controlling highway route quality.Taking MATLAB as the experimental platform,based on genetic algorithm fitness function and genetic operation programming,this paperrealizes the automatic optimization of highway route selection scheme through parameter setting.An example of route selection shows that the intelligent route selection method based on genetic algorithm can automatically and randomly search the intersection point of highway route in the route selection area,and automatically complete the optimization of highway route to obtain the best highway route scheme.It turns out that the automatic route selection scheme can be optimized to improve the efficiency and quality of route selection.
