揭秘春运售票高峰中的12306：每天PV超400亿次 - 12306,春运,高铁 - IT资讯
随着网络购票盛行，12306网站、手机客户端成为春运铁路购票的重要渠道。今年春运售票的情况怎么样？哪些线路是热门？什么时间会放票？记者探访了中国铁道科学院全路客票系统监控中心，与中国铁道科学研究院电子计算技术研究所研究员朱建生对话，揭秘春运售票高峰中的12306。
今年互联网售票超七成
记者在中国铁道科学研究院全路客票系统监控中心看到，12306的技术支持部门正在几百平方米的大厅集中办公。大厅内人头攒动，工程师们不断就各种技术问题商议、解决。大屏幕上实时显示着12306网站大数据分析的动态情况：一次订票交易平均响应时间500毫秒、网站PV值每天超400亿次……
问：今年春运的售票情况如何？
答：截至目前，日售票量最高为12月23日(预售腊月二十四车票)，当日全路共发售车票1167.2万张。其中互联网发售855.6万张，较去年春节最高峰增加了213万张。网络售票占全路总售票量的73.3%，其中手机APP发售576.2万张，占网络售票的67.3%。
互联网售票越来越受到青睐，手机APP购票近七成，体现了售票渠道的变化特点。截至目前，已有累计超过2亿部手机下载了12306手机APP，近一半春运客票是通过手机客户端购买的。
热门车次几分钟售罄
问：今年哪些线路是热门线路？
答：今年春运的热门线路包括：北京地区到郑州、西安、武汉和东北等方向，上海地区到武汉、成渝、郑州、长沙、南昌和贵阳等方向，广州地区到武汉、贵阳、成渝和南宁等方向。
从目前已售车票的大数据分析可以看出，春运首日出发客流最高的城市为：广州、北京、上海、深圳和武汉；到达客流最高的城市为：北京、重庆、武汉、成都和西安。
热门车次的全部车票基本在起售后几分钟就发售一空，说明铁路是春运非常受欢迎的交通方式。
一天21个放票时间
问：12306春运期间怎么放票？
答：12306的放票时间从最初的一天4个放票时间点，增加到10个，再到现在每天21个放票时间点。从8时开始到18时，每半个小时放票一次。
每个车站在21个时间段只有一个对应的放票时间，因此，乘客只要记住乘车站的售票时间就可以了。比如北京西站8时00分放票，北京站10时00分，北京北站12时00分，北京南站12时30分。12306网站、手机APP首页和铁路12306微信公众号，均可查询起售时间。
云查询每秒40万次
问：12306如何应对超大访问量？
答：从2014年开始，我们把网站访问量最大的查询业务分担到“云端”。今年进一步扩大了云端容量，几乎100%的查询访问都在云端进行，查询能力可以达到每秒40万次。今年的数据显示，网站一天的查询量达到250亿次。
12306网站非常重视个人信息的保护。网站和客票核心系统严格遵循国家信息安全等级保护的相关规定构建，对个人信息等加密存储和处理。云端只提供车票查询服务，不会涉及乘客购票的个人信息。需要提醒乘客的是，不要把12306网站用户名和密码透露给抢票软件或者代购网站，避免泄露出行、联系人等信息。
技术层面4招治“黄牛”
问：“黄牛”倒票从线下发展到了线上，有哪些技术手段来维护售票秩序？
答：第一，我们控制了退票返库的时间，退出的票不会马上返库，而是随机放出，防止一些倒票人员退票后马上抢票。
第二，设计了后台冲突判断机制，对购票行为进行分析。比如，一个人的身份证同时购买了当天从北京到成都、从上海到贵阳的车票，我们会实时进行分析。这种“冲突”的情况今年起可以全路线上线下售票渠道联合判断，改进了以往线上和线下分离的情况。
第三，对购票行为异常的账户、地址等进行大数据分析，实施风险防控措施。比如一些访问频度过高或者刷票过快的IP地址，会进行处理。
第四，通过验证码控制热门线路刷票。没有抢票需求的线路已经不再生成验证码，目前来看比例超过60%。
这些都是针对倒票行为的限制，正常旅客访问网站不会受到影响。我们希望兼顾购票便利的同时，维护网站的售票秩序，希望每个人都能买到回家的车票，过一个温暖、团圆的春节。
