基于遗传算法的城市混合型路网设计问题研究

针对目前城市路网设计中存在的一些缺陷，提出一种基于遗传算法的城市混合型路网设计的多目标优化模型，它可一次性求得多个可供规划决策者进行选择的路网设计方案，并利用一个算例进行仿真试验，结果表明，该模型和算法是可行的、有效的，可以为城市路网规划提供借鉴。

Study on urban mixed network design problem based on genetic algorithm

In order to reduce the deficiency in urban road network design, a multi-objective optimization model of network design based on genetic algorithm was presented in this paper, which can calculate a lot of layouts of road network for decision-makers. A simulation test has been made in an urban road network design by using the model and algorithm. The results indicate the model and algorithm are feasible and effective, and they have provided a reference for urban road network design.
