For research  by Claudio Silva of New York University and his colleagues suggests that  the two have  a striking resemblance  when  it comes  to   the  daily   ebb  and flow of tourists, as judged from  the level of activity  on Flickr, a photo-hosting site.Dr Silva thinks  the peaks  and troughs of Flickr activity that  his research has discovered  in this and other cases  are  a measure of  an area' s "urban pulse" .

Dr Silva's work  is part of  a broader trend, dubbed "smart cities" by some,towards using  the vast amounts  of data generated  by  the inhabitants  of urban areas  to make them better places  to live.Carlo Ratti and  his colleagues  in the Senseable City laboratory  at  the Massachusetts Institute of Technology（MIT）, for example,used mobile-phone records,and also  traffic data from 500 pressure sensors on roads,  to help guide construction of  the new metro system  in Saudi Arabia's capital,Riyadh.

Silva博士的工作是有些人称为“智慧城市”这种总体趋势的一部分，趋向于通过使用从城市居民那里得到的大量数据来使他们生活地更好。
