Taxis Drive Smart City Creation

As the world has advanced technologically, the word "smart" has been applied to everything from smartphones to smart homes. Everything is "smart" now, including cities. A smart city utilizes various Internet of Things (IoT) sensors to collect data around the city, which is analyzed to better run and manage the city's resources and services. Some applications include traffic congestion, noise, and pollution control, among others. All these applications require data, and more specifically, accurate learning requires good data. This leads to one of the major problems with developing smart cities: cities are large. Beijing is 1,600 square miles with a population of more than 20 million, while comparatively, New York City is 302 square miles with more than eight million.
