Context: Foundations of the TechniCity

  • Large-scale urbanization is driving the need for innovation and new technologies.
  • Smart cities is about all the ways technology can be used to:
    • improve the quality of life for people;
    • improve the efficiency of services;
    • and support the quality of our environment (e.g. healthy, clean).
  • Three concrete examples of how technology can be integrated into our cities to allow city planners and others to create smarter cities:
    • Making sure people can move through our cities (e.g. using video cameras to count pedestrians and analyze the video feed)
    • Capturing surveillance video t0 identify when traffic rule violations happen, enabling citations to be sent to the violators.
    • Helping people understand their level of water consumption, or how it compares to others.
  • We have to think holistically to have smart city planning as the different elements are all connected.

Context: Thinking Cities

  • Network society city index: ranks cities from around the world based on their ability to transform technology into social, economic, and environmental benefits.
  • Research shows that the bigger the city, the more it has of everything, whether it is wages or AIDS cases or crime, or patents.
  • The important thing to recognize about cities is that:
    • on the one hand, the exponential urbanization is the origin of the feeling of a tsunami of problems;
    • on the other hand, the great thing about cities is that they are vacuum cleaners or magnets that suck up human creativity, ideas, culture.
  • So whereas on the one hand the problems are generated in cities, the solution is going to be generated in cities.
  • It is of great urgency that we understand cities in a profound and predictive fashion, and today, for the first time, our cities are becoming like real-time control system.
  • Technology is now becoming itemized, distributed, and radically changing the way we interface with the city – it means that the city, all the buildings, all the objects are starting to respond to us, to talk back to us.
  • Visionary mayors who get it, are incredibly enthusiastic about the future of cities, and are very enthusiastic about introducing ICT tools into city management.
  • Case study of  Stockholm, Sweden, which makes it as easy as possible for people to live in a smart and sustainable way.

Context: Smart and Connected

  • Important to take multidisciplinary approach as we are thinking about the future of cities and the relationship to new technologies.
  • Science of cities: lots of different kind of data and information that can be collected, analyzed and used to make better decisions.
  • If we want to address sustainability issues, cities are not a bad place to start: how the world cities develop their infrastructure over the next 30 years will determine the future path of global warming.
  • Research explores whether there are mathematical formulas that can be applied to cities development e.g. if you double the population of a city, the infrastructure increases by 85% (the 15% efficiency is a scaling effect i.e. do not need to double the amount of infrastructure to support twice the number of people).
  • This formula also seems to hold for other dimensions e.g. wages, GDP, productivity, the number of super creatives in the city (defined by number of patents).

Context: From Smart Grids to Smart Cities

  • Smart grid provides the foundation for different systems and for liveability in a smart city.
  • If you’re going to look at the components of a smart city, the two most essential and most fundamental are energy and telecommunications – they go hand-in-hand in a smart grid.
  • There are three aspects
    • collecting information about the city’s conditions;
    • communicating those conditions to where it matters;
    • crunching the data to create insights and value.
  • Smart grids and smart cities give citizens and businesses in that region a competitive advantage.

Case Study: Mesh Networks

  • Turn to technologies that make community networking possible e.g. mesh networks.
  • A network is just a collection of devices that talk to each other in order to move information or data from one point to another.
  • In a mesh network, the routing protocol chooses the route that can move the traffic most efficiently and most easily from one point to another (unlike a hub and spoke network where traffic has to go through a central point).
  • Advantages of mesh networks:
    • Anybody can add a node, and that node will automatically figure out how to talk to the other nodes in the network;
    • They are self-healing – if one node is removed or breaks, the network will figure out how to route traffic around it.
    • They are thus more resilient.
    • Multiple smaller mesh networks can also be joined together to make bigger networks, creating a network that is separate from the global Internet.
  • Local governments can encourage the development of neighborhood networks and then help link them together into one system.
  • Case study: guifi.net, arguably the largest community network in the world.
