How Big Data and Internet of Things Build Smart Cities“Smart City” is a term we’ll hear a lot more of in the coming years. It’s estimated that by 2020, we’ll spend $400 billion a year building them. Cities being “smart” is not about algorithms only, of course; there are many things that can be done without too much monitoring. And, above all, there needs to be an overall strategy in place, otherwise, we might end up with tons of pilot projects that we don’t really know what to do with. As the population is growing, people are increasingly shifting to urban areas. According to a 2014 UN report, 54 percent of the world’s population resides in urban areas, and this share is expected to go up to 66 percent by the year 2050. “Smart Cities” is this umbrella initiative that is designed to make urban areas more livable, agile and sustainable.
