本次合作伙伴，尹坤，
本次项目花费时间10小时，
项目一开始是自己建立数据库
数据库结构：
1 DROP TABLE IF EXISTS `subway`; 2 CREATE TABLE `subway` ( 3 `id` int(11) NOT NULL AUTO_INCREMENT, 4 `stop` varchar(255) DEFAULT NULL, 5 `route` int(255) DEFAULT NULL, 6 `position` int(255) DEFAULT NULL, 7 `exchange` int(255) DEFAULT NULL, 8 PRIMARY KEY (`id`) 9 ) ENGINE=InnoDB AUTO_INCREMENT=159 DEFAULT CHARSET=utf8;

利用对数据库的遍历查询：
一：若起始站和终点站在同一条线路上，则直接进行查询遍历
二：如起始站和终点站在不同线路上，则对数据库进行遍历，查找中转站，并按起始站到中转站，中转站到终点站进行遍历；
但是存在问题：
一：无法反向遍历查找
二：无法查找转站三次以上的线路
之后我们调用百度地图的API进行操作，简化了算法

结合Javascript进行线路规划：
很高兴
很高兴这次的合作，希望以后有机会还能合作！
