Baidu built an A.I. that predicts dangerous crowds and stampedes

It was December 31, 2014. In Shanghai, thousands flocked to the historic and picturesque Bund, where there had been reports a light show would take place to ring in the new year. Unfortunately, too many people had the same idea. A dangerously dense crowd formed, and at a viewing platform in Chen Yi Square overlooking the river, confusion and a lack of crowd control led to panic and eventually stampede. Within minutes, 36 people had been killed and another 49 had been injured in the crush.
