The Rise of the Smart City
The information revolution is changing the way cities are run - and the lives of its residents. Cities have a way to go before they can be considered geniuses. But they’re getting smart pretty fast.
In just the past few years, mayors and other officials in cities across the country have begun to draw on 【1】 - about income, traffic, fires, illnesses, parking tickets and more - to handle many of the problems of urban life. Whether it’s making it easier for residents to find parking places, or giving smoke alarms to the households that are most likely to suffer fatal fires, big - data technologies are beginning to 【2】 the way cities work.
Cities have just 【3】 the surface in using data to improve operations, but big changes are already under way in leading smart cities, says Stephen Goldsmith, a professor of government and director of the Innovations in Government Program at the Harvard Kennedy School. “In terms of city governance, we are at one of the most 【4】 periods in the last century,” he says.
Although cities have been using data in various forms for decades, the modern practice of civic analytics（民情分析）has only begun to take off in the past few years, thanks to a host of 【5】 changes. Among them: the growth of cloud computing, which dramatically lowers the costs of storing information; new developments in machine learning, which put 【6】 analytical tools in the hand of city officials; the Internet and the rise of inexpensive sensors that can track vast amount of information such as traffic or air pollution; and the widespread use of smart phone apps and mobile devices that enable citizens and city workers alike to monitor problems and 【7】 information about them back to city hall.
All this data collection raises understandable privacy 【8】. Most cities have policies designed to safeguard citizen privacy and prevent the release of information that might 【9】 any one individual. In theory, anyway. Widespread use of sensors and video can also present privacy risks unless 【10】 are taken. The technology “is forcing cities to face questions of privacy that they haven’t had to face before,” says Ben Green, a fellow at Harvard’s Berkman Klein Center for Internet and Society and lead author of a recent report on open-data privacy.
