7.1 Modelling City Services

Cities have deployed services in the past as silos due to an unintegrated city vision, where all services made its
systems, networks and devices think only about its specific service requirements.

The future of Smart Cities goes to reuse resources in different services and think deployment in terms of a common
conceptual management of resources (networks, databases, systems evolving from legacy to a new public
management space model.

Moreover, it will be a key issue to have a common definition of services where we can distinguish between services
perceived by users (Final Services) and its parts as service (Basic Services).
All Basic Services could be modeled to a “Standard City Reference Unit” that permits city government to see most of
the city’s services in terms of repeatability.
For example, in Barcelona they use “Macroblock/Superblock” (Supermanzana in Spanish). Macroblocks are defined
theoretically as an "area of urban organization, from which a series of structured transformation strategies towards a
new urban model, where mobility and reorganization of public space represent the first step”. They represent a
population between 5,000 and 15,000 in an area without car traffic surrounded by high traffic streets. That permits a
model/service in the Superblock area (i.e.: 2 sonometers/macroblock), and as a consequence, obtains a model for all
the cities model as addition of macro blocks.

A clear definition of roles for ICT components in final services follows:
• City Council Technical Service Users (Police, Firefighter, Inspectors,..) define QoS:

o Physical parameters will be measured,
o Kind of sensors/actuators that will be used for a specific service,

o Position for specific purpose
