摘要：为使大城市周边城镇道路网规划更为合理，首先分析了最主要的2类城镇的发展模式和出行特征。基于规划年城镇交通供需平衡原则，提出了大城市周边城镇道路网级配合理性的判定方法。建立了路网级配结构合理性判定模型，并对模型参数进行了标定。以江苏省昆山市花桥镇为例，计算相关变量，对道路网级配结构合理性进行了判定，并对路网级配结构提出相应的调整建议，验证了合理性判定方法的实用性。

Abstract：Aimed at realizing rational planning for road networks in towns around metropolitan areas, the paper starts with an analysis on development patterns of two main types of towns and their travel characteristics. Based on the principle of balance between traffic supply and demand for a target year, this paper proposes an approach to evaluate the rationality of road networks in towns around a large city. A model for evaluating the structure rationality of road networks is established, followed by parameter calibration. Finally, the paper illustrates an application of the model to evaluating the structure rationality of road networks through a case study in Huaqiao, Kunshan (Jiangsu province). Relevant variables are calculated, and suggestions for adjustments are proposed correspondingly to the results.
