Vol.050 如何为十三亿人调度列车 | 回形针

If you are onboard train G(Gaosu-High speed)1928 from Shanghai Hongqiao bound for Xi’anbei(Shannxi) It’s now 14:40, just 5 minutes ago the train left from Nanjingnan Station 12 minutes later, the train will stop at Chuzhou(Anhui) Station for 5 minutes so as to wait for the G136 bound for Beijing to pass by; then the train flies in a 300kph(186mph) speed and enters the busiest section of Beijing-Shanghai HSR Bengbunan(Anhui) to Xuzhoudong (Jiangsu) section Afterwards, the G330 from Fuzhou(Fujian) waits there to let your train pass by and the former will keep a 4-minute distance with the latter But both trains will wait at Suzhoudong Station(Anhui) to wait for G4, a Fuxing series EMU to pass by Finally you will be on your course to Xi’an via the Zhengzhou-Xuzhou HSR from Xuzhoudong Station These train’s schedule are tightly-related to each other All these trains above will be delayed if an accident has occured on ANY of these trains listed Eventually affects ALL trains using the Bengbunan to Xuzhoudong section Or even worst-the whole railway network of PRC PaperClip Vol.050: How do you control the train traffic for 1.3 billion people Different from the schedule shown on the www.12306.cn (The online ticketing system of China Railway) What the trains relied on is the train graph(On the right) It looks something like this… Each line represents a train X-axis means the time while the Y-axis represents the stations on the railway line And each line represents the relative position of trains on a given time These lines are called train paths It is normal for a faster train catches up a slower one on a railway with differentiated speeds It means a collision when two lines crosses each other For this, slower trains need to go into a passing loop(待避) For a normal-speed railway (Defined in PRC as railway lines with operational speed lower than 160kph) Trains started with Z (直达特快,Zhida tekuai, lit. Non-stop express) is the highest priority among those running on normal-speed With the speed topped at 160kph Then it comes to T trains (特快,Tekuai; lit. Express) with 140kph top speed Finally with K trains(快速,Kuai su; lit Rapid);Normal-rapid(普快)/Normal(普客) trains with no preflex Running normally at 120kph and below In the past(

  1. 想起来之前从北京坐高铁还是动车来着,记不清了,回青岛,一开始的确是挺快,呼呼的,没几个小时就到山东境内了,之前坐火车都要一晚上的。结果进入山东内就开始减速了,跟火车一样慢,最后也是用了好久才到青岛

  2. 160的动集就不能叫动车组!更不能按动车组标准收费!可惜了,有专家为此发声,奈何老百姓都是文盲,任人宰割。

  3. 一直很好奇高铁列车是怎么调度怎么协调的,终于看到😇😇😇 —科学上网,解锁外网,严苛测试,支持电脑手机全网段超清,多开使用,1元成交,每月只需12.9元,注册体验双免费,VPN长期服务网址:deyun124点xyz
