What is the whole rationale behind making cities smarter?
Well, there are a number of factors. For one, the world’s population has doubled in the last 40 years (from 3.5 billion to almost 7 billion). And with the mushrooming population, there is also an increase in urbanisation (in 1800, 3% of the world’s population lived in cities, whereas in 2007 that figured went above 50% for the first time).
The surging numbers of people living in cities are increasing demands on municipalities for services like water, energy, transportation, housing, healthcare and public safety. This is happening at a time of constrained resources and ageing infrastructures for many existing cities.
At the IBM Smarter Cities event, IBM showcased both some of the technologies they are providing to cities and also case studies of some of the solutions they have rolled out.
The core of IBM’s offerings is its Intelligent Operations Center (IOC) – this is a application capable of taking information from virtually any IT system a city may have (water management, video surveillance, first responder systems, traffic management, etc.), combining this data and using it to kick off workflows, to trigger alerts, to display on dashboards and/or for data export.
The fact that the system can take in inputs from such a wide variety of systems is, in large part due to its use of the Common Alerting Protocol (CAP) – an XML-based protocol for exchanging alerts between systems. From the CAP Wikipedia entry:
Alerts from the United States Geological Survey, the Department of Homeland Security, NOAA and the California Office of Emergency Services can all be received in the same format, by the same application. That application can, for example, sound different alarms based on the information received.
The IOC’s flexibility when it comes to data inputs ensures it can take in information from almost any IT system…
