最近看了新周刊的一篇推送，有关地铁名字的分析，链接如下。

我们分析了3447个地铁站，发现了中国城市地名的秘密

于是乎也想着自己去获取数据，然后进行分析一番。

当然分析水平不可能和他们的相比，毕竟文笔摆在那里，也就那点水平。

大家看着乐呵就好，能提高的估摸着也就只有数据的准确性啦。

文中所用到的地铁站数据并没有去重，对于换乘站，含有大量重复。

即使作者一直在强调换乘站占比很小，影响不是很大。

但于我而言，去除重复数据还是比较简单的。

然后照着人家的路子去分析，多学习一下。

/ 01 / 获取分析

地铁信息获取从高德地图上获取。

上面主要获取城市的「id」，「cityname」及「名称」。

用于拼接请求网址，进而获取地铁线路的具体信息。

找到请求信息，获取各个城市的地铁线路以及线路中站点详情。

/ 02 / 数据获取

具体代码如下。

最后成功获取数据。

包含换乘站数据，一共3541个地铁站点。

/ 03 / 数据可视化

先对数据进行清洗，去除重复的换乘站信息。

通过城市及地铁线路进行分组，得到全国地铁线路总数。

一共183条地铁线路。

已经开通地铁的城市数据，还有各个城市的地铁线路数。

一共32个城市开通地铁，其中北京、上海线路已经超过了20条。

城市分布情况。

大部分都是省会城市，还有个别经济实力强的城市。

线路数量分布情况。

可以看到大部分还是在「0-5」这个阶段的，当然最少为1条线。

探索一下哪个城市哪条线路地铁站最多。

北京10号线第一，重庆3号线第二。

还是蛮怀念北京1张票，2块钱地铁随便做的时候。

可惜好日子一去不复返了。

去除重复换乘站数据。

一共包含3034个地铁站，相较新周刊中3447个地铁站数据。

减少了近400个地铁站。

接下来看一下哪个城市地铁站最多。

32个城市，上海第一，北京第二。

没想到的是，武汉居然有那么多地铁站。

现在来实现一下新周刊中的操作，生成地铁名词云。

统计一下，大家最喜欢用什么字来命名地铁。

路最多，在此之中上海的占比很大。

不信往下看。

统计上海所有的地铁站，一共345个。

选取包含路的地铁站。

有210个，约占上海地铁的三分之二，路的七分之二。

看来上海对路是情有独钟的。

具体缘由这里就不解释了，详情见新周刊的推送，里面还是讲解蛮详细的。

武汉和重庆则是对家这个词特别喜欢。

武汉共有17个，重庆共有20个。

一共有21个城市，地铁站名包含门。

其中北京，南京，西安作为多朝古都，占去了大部分。
