Baidu’s Big Data Lab has released a paper detailing how to use big data analytics to predict large-scale crowd formation and warn people of potentially deadly stampede events, like the tragic one that claimed the lives of 36 people in Shanghai on New Year’s Eve, 2014.
The paper is titled “Early Warning of Human Crowds Based on Query Data from Baidu Maps: Analysis Based on Shanghai Stampede.”
Baidu’s Haishan Wu, an author of the paper, told the Wall Street Journal that his team started to focus on crowd-formation predictions after the Shanghai stampede.
“Our algorithm is able to use crowd data from Baidu Maps to predict how many people will be [at a certain location] in the next two hours,” Mr. Wu said.
