It seemed like a mission impossible, a dream too big, especially for a 15-year-old, yet that dream came true in 2015,
這看起來像不可能完成的任務，完全是異想天開，尤其對于一個15歲的人來講，但夢想在2015年成真了，
when not only did we succeed in reducing the stampedes and their intensity,
我們不僅成功降低了踩踏事件發生的次數和密度，
but we marked 2015 as the first Nashik Kumbh Mela to have zero stampedes.
也在2015年實現了大壺節歷史上首次零踩踏事件的突破。
It was the first time in recorded history that this event passed without any casualties. How did we do it?
這是有歷史記錄以來第一次這個節日上沒有任何人員傷亡。我們是如何做到的？
It all started when I joined an innovation workshop by MIT Media Lab in 2014 called the Kumbhathon
這一切始于我加入的由MIT媒體實驗室在2014年設立的名叫大壺馬拉松的創新研討會，
that aimed at solving challenges faced at the grand scale of Kumbh Mela.
目的是解決大壺節面臨的大規模人群挑戰。
Now, we figured out to solve the stampede problem, we wanted to know only three things:
現在，我們知道要解決踩踏問題，只需要知道三件事情：
the number of people, the location, and the rate of the flow of people per minute.
人數，他們的位置，和每分鐘人流的速度。
So we started to look for technologies that would help us get these three things.
所以我們開始尋找可以幫我們得到這三種信息的科技。
Can we distribute radio-frequency tokens to identify people?
我們可以通過無線標記來識別人群嗎？
We figured out that it would be too expensive and impractical to distribute 30 million tags.
我們發現，這個方法可能太昂貴且不實用，需要分發超過3千萬標記。
Can you use CCTV cameras with image-processing techniques?
能不能用帶圖像識別的電子攝像頭呢？
Again, too expensive for that scale,
同樣，對于此等人群規模實在太昂貴了，
along with the disadvantages of being non-portable and being completely useless in the case of rain,
而且還有不夠便攜的缺點，遇到雨天這樣的天氣時基本毫無用處，
which is a common thing to happen in Kumbh Mela. Can we use cell phone tower data?
大壺節遇到下雨可是非常平常的事情。我們可以使用蜂窩基站的數據嗎？
It sounds like the perfect solution, but the funny part is,
這聽起來像是個完美的解決方法，但有趣的是，
most of the people do not carry cell phones in events like Kumbh Mela.
很多人在大壺節這樣的節日上，根本不帶手機。
Also, the data wouldn't have been granular enough for us.
而且這個數據對我們而言粒度不夠。
So we wanted something that was real-time, low-cost, sturdy and waterproof,
所以我們想要真正實時的，低成本的，堅固的，防水的，
and it was easy to get the data for processing.
而且便于獲取數據的方案。
