In the ordinary way, a smart city is a system of managing municipal services, which makes it possible, for instance, to save resources. This happens during an important stage in the development of cities in terms of shifting from industrial to postindustrial and further on to digital society. But when clerks start thinking about it, as a rule, they stay on the communal administrative plane, discussing CCTV systems, lighting, garbage disposal etc.
Im sure that the topic of smart cities is much wider. The most important thing is that smart cities can define the new format of communication among residents, authorities and various city communities. And, in the end, this will increase comfort and quality of life.
Concentration of people in cities is rising; urbanization is not going to stop. Traditional methods are not working any longer for the required communication among such large number of people. Without feedback, people get the feeling of detachment; they don't believe that their opinion can be heard. As a result, discontent or apathy grows in the absence of participation in urban development.
I rather like the definition of a smart city as an urban neuronet, where numerous communications take place, and they are structured in a specific way. There are a lot of internet services now from common car-sharing to booking accommodation and state services, which could be united into one system, according to citizens' requests. As part of this system, one could collect data on citizens, get information about their interests, needs and preferences.
