Today, the ten most populated cities have over 268 million people, with around 26.86 million people living in their urban areas. If in a few years’ time 70% of the population will live in cities, perhaps it would be interesting for cities to be able to work as smart entities.Brain cities no longer form part of hard science fiction. Thanks to technologies such as Amazon Rekognition, used in Orlando, Florida and Washington County (Oregon) or Alibaba City Brain, used in Hangzhou, capital of the province of Zhejiang (China), the idea of smart cities is getting closer to the literal sense of the term.
This is how City Brain works in Hangzhou
Imagine having the GPS of the majority of a city’s vehicles in a single database, as well as real-time data from video cameras, traffic lights or updated maps of the city; and this information is added to the historical data from previous days, weeks and months.The result is CityBrain, Hangzhou’s total traffic control system designed by Alibaba, which the city’s local government could not refuse. The private consortium began in Hangzhou a few decades ago as distributors of goods and today they are leaders in the capture, aggregation and management of data.
Amazon Rekognition, software used by the police
Police all around the world are beginning to use artificial intelligence tools, enabling cold cases to be rescued and launching virtual baits to trap dangerous delinquents. AI is also behind the European programme VALCRI to identify potential suspects. Likewise, in the US, Amazon Rekognition is being successfully tested.Rekognition operates in a similar way to City Brain or Agricultural Brain, the latter also run by Alibaba, but focusing on the agricultural sector. The system is optimized based on patterns, and in this case the patterns are people.
