| 摘 要： | 中国长期传统封闭的生活和工作模式，使城市存在大量的封闭式居住和单位（含公共活动）小区，这些小区内部道路不列入城市道路范畴，外部出行者不能从小区中间穿越。本文从影响交通便捷的因素可替代路径入手，提出了了方形小区对城市方格交通网络的影响度度量指标——任意起讫点对间交通便捷度方形小区影响因子和网络交通便捷度方形小区影响因子的定义．给出其计算方法和性质，并结合西安市交通网络进行了实例分析。目的在于为城市道路改造和新道路设计提供依据。

| Abstract: | The numbers of big close blocks surrounded by the wall are subsistent on city transportation network in China for long traditional close life and work, so the traveler can not across the block via the road in it which do not belong to city transportation network. In order to giving a suggestion to policy-maker, a concept of transportation convenience coefficient of square block is proposed for the transportation convenience capability measure on a grid network. An algorithm is proposed and the characters of coefficient are analyzed for arbitrary couple of vertices and a network. Finally, a practice example analysis is shown and the algorithm is validated. |
