前言

1.公交车站的意义

• 转变现有出行模式，倡导公共交通和混合动力汽车、电动车、自行车等低碳或无碳方式，同时也丰富出行生活，增加出行项目。
• 扭转奢华浪费之风，强化清洁、方便、舒适的功能性，提升文化的品牌性。
• 加强出行智能化发展，提高运行效率，同时及时全面引进节能减排技术，降低碳消耗，最终形成全产业链的循环经济模式。

2.公交车站的作用

• 对老百姓来说，公共汽车出行，成本低廉。
• 对国家来说，公共汽车可以减少私家车的出行，对大自然来说是环保的。
• 公共汽车可以减少交通压力。
• 公共汽车往往能涵盖这个城市的绝大多数地区，对偏远地区来说是很方便的。

一、周边站点

小程序的周边站点是实时获取当前登录用户的位置信息，进而给出附件公交车站信息，以便用户选择乘车方案。
