基于城乡一体化的公交线网优化模型研究

Optimization Model for Transit Network Based on Urban-Rural Unification

在基于若干假设的前提下,用数学寻优法建立城乡公交线网优化模型,其上层规划以最小化公交车运行时耗为目标,下层规划以最小化乘客步行距离为目标,最后采用遗传算法来求解算例。结果表明,合理设置公交站点能优化公交线网。

This issue uses a mathematical optimization method to establish a public transportation network optimization model for urban and rural areas on several assumptions,in which the top planning takes minimize the buses run-time of consumption as the goal,and the lower planning takes minimize the walking distance of passengers as the target.Finally,the genetic algorithm is used to solve the numerical example.The result shows that reasonable setting of bus station can optimize transportation network.
