You don’t need to look to the future to spot the problems with cities – take a look at the roads instead. Cars clog up arterial roads. Pollution hangs heavy in the air. And housing is scarcer and more expensive than ever before. There are also issues with the water supply, power supply and waste disposal in many cities. We need smart solutions, right now! Cities such as Barcelona, Copenhagen, Vienna, Singapore and Dubai are paving the way for us all here.
The challenges differ from city to city, but the ideas are similar. A smart city collects data via sensors and makes this information publicly and freely available. Everything is networked: Public parking spaces, street lights, traffic lights, public bus services, cars, houses, apartments, electric companies, city and town councils, the police and so on. Smart devices are also moving in with us: Your smartphone talks to your refrigerator, heating, coffee machine, roller blinds, washing machine... It can even control your parking heater to pre-heat your car in winter.
Our cities are becoming increasingly smart and networked.
