City Activity Stream application has been developed within "Adaptive Cooperative Control in Urban Subsystems" project (ARTEMIS/FP7). It uses complex event processing technology to discover urban events in data sourced from many different urban systems.

name definition data used (source)
traffic congestion congestion beyond (average)
2000 vehicles / h
traffic measurements
(Tristar ITS, Street Traffic Radars)
high PM10 concentration PM10 concentration in the air exceeds
the norm of 25 µg/m3
air quality measurements (pollution
monitoring system)
strong wind speed of wind beyond 3 m/s weather subsystem
cold temperature below 0 °C weather subsystem
road incident road incident affecting traffic operator input (Tristar ITS)
parking zone full number of vehicles in the parking zone
reaches its full capacity
counter (Automatic Vehicle
Identification)

4. Cross-domain complex event: difficult road conditions
Tristar ITS
Street Traffic Radars
Weather Subsystem
temperature below 0°C
& high traffic congestion

5. Architecture
and data flow

6. The application (GUI)
Traffic congestion, PM10 level, and parking zones over time.

7. § optimization of combined performance of urban systems prerequisite:
§ sensing capabilities on system of systems level
§ data sourced from many different subsystems:
§ Tristar ITS, Street Traffic Radars, Numerical Weather Prediction, Automatic Vehicle
Identification, Air Pollution Monitoring
§ cross-domain application in information domain:
§ CAS and CEDE go beyond the silo-architecture of isolated urban systems and
enable horizontal data integration for event detection and processing purposes
§ enhanced situational awareness on SoS level:
§ SoS provided with an emergent capability to detect events that cannot be spotted
by any of the sensing subsystems as stand-alone
SoS-level sensing and event processing

8. CAS & CEDE: future development agenda
EVENT DETECTION FOR GRITTER
ROUTING SOFTWARE
Next step is to use weather forecast
and Tristar ITS traffic simulation
capabilities to predict difficult road
conditions for upcoming 12 hours.
Predicted events will define routes for
gritter-vehicles for improved road
safety in urban areas during the winter
season.
CUSTOMIZED NOTIFICATIONS
FOR CITIZENS
The goal is to mature the mobile-client
prototype and enable customized
notifications on urban events, including
traffic jams, weather, concerts, road
works, etc.
Think of IFTTT that operates on urban
systems.
SITUATIONAL AWARENESS FOR
URBAN DEPARTMENTS
City authorities will get access to GUI to
define own events and assign them to
appropriate city services.
Delivered events will trigger relevant
behavior and enable evidence-based
decision making in urban departments.
