春运火车票为啥放票瞬间就没了?12306回应系列热点

2018年春运已在2月1日正式启动。带着“为什么一放票,所有的票就都没了?”“用抢票软件的话,是否会影响在12306正常购票?”“未来是否能够24小时全天售票?”等网友的问题,中新网记者探访铁路12306客票中心,对相关负责人进行了采访。
发售春运车票以来已售了多少张?
官方预计,今年春运全国铁路预计发送旅客3.9亿人次,同比增加3131万人次,日均955万人次。
12306公布数据显示,1月3日发售春运车票以来,截至2月1日共发售3.5亿张车票,其中互联网售票继续为主渠道售票2.8亿张。春运期间出售的火车票首尾相接,接近绕地球1圈。
虽然仍需“提前抢票”,但今年春运购票体验与往年相比有所不同,售票过程变得更加快捷顺畅,购票成功率也有所提升。
这是因为技术人员对12306系统进行了优化。热门方向车票放票时间等有所不同,把压力进一步分担;80%到90%,甚至部分时候90%以上车票不需输验证码;单日售票能力从1000万张提高到了1500万张。
“在高峰时段,1秒可以售出近700张票。”中国铁道科学研究院电子所副总工程师兼12306技术部主任单杏花表示,“2012年刚上线时,1秒最多只能售出几十张票,低的时候只有几张。”
为什么一放票,所有的票就都没了?
“秒光!”有网友说,自己在12306手机APP准时抢票,网速也不慢,但一到放票时间点,所有的票就都没了,这是为什么?
“因为抢票太热,”单杏花说,高峰时段1秒售出近700张票,这意味着,一秒钟把一辆热门动车组的车票全秒杀走了,稍微慢一点就会买不到票。
她在解释购票流程时说,用户查到有票后填写乘车人信息,在点击提交按钮的时候就开始排队,按时间顺序出票。1秒钟内可能有很多人提交,区分的时间会具体到毫秒。
还有一种情况是,明明显示有余票,但提交时发现没票了,这是为什么?
单杏花说,抢票的旅客非常多,余票也在实时变化。由于所有售票渠道的车票都是共享的,如果12306网站上显示没票,那么去车站或打电话也不会买到票。
长期用抢票软件会影响正常购票?
有的抢票软件可以实时刷新抢票信息,在线监控是否有漏票或退票。长期用这类软件,是否会影响旅客在12306的正常购票呢?
“有这种可能,”单杏花说,“长期用抢票软件的话,如果正常买,反而会比别人慢。”
她解释说,12306后台有风控,通过大数据分析,可以识别危害系统、影响系统稳定的行为,并进行拦截处理。对抢票软件做了一定的防范,避免对系统的稳定运行造成影响。
值得注意的是,今年的抢票软件并不好用。此前有报道指出,记者购买2月13日的北京-德州的火车票,指定了几个车次,在放票前启动某抢票软件,依然抢票失败。
未来是否能够24小时全天售票?
目前12306的售票时间是每天6点到23点。每天23点至次日6点期间,12306系统会进行数据整理和维护,以保证第二天售票系统“轻装上阵”。
对于未来是否能够24小时全天售票,单杏花告诉中新网记者,目前正在研究中。
2017年,12306开通了互联网订餐、接续换乘、动车组自主选座、“铁路畅行”常旅客会员、复兴号座星系统、购票通知短信转微信、自动售票机发售异地票、行程提醒、微信小程序余票查询和行程管理、车站二维码余票查询等便民服务措施。
单杏花说,会进一步丰富服务功能,包括信息查询功能、已推出的铁路畅行长旅客会员等,利用新技术,把更新的功能、服务推上去。下一步用身份证购买车票后,可以直接刷身份证乘车。
