Context, Motivation and Needs

Henry Muccini @ ICSA2017

Our practical needs: to engineer crowd

management systems


4

spin-off of the University of L’Aquila

Crowd management Indoor | outdoor

Queue forecast and avoidance

Multi-site crowd management

Digital Booking and Ticketing


5crowd monitoring and control5


6crowd monitoring and control6

Q: How long will take to get into the entrance?

do: people counting tech

to know: arrival frequency

to know: pick hours

Q: How long took to visit the place?

do: people tracking tech

to know: time spent in averageto know: time spent in areas


7: multi-sites of interest7

Q: How to load balance? Q: how to re-route people?


8The context of this research Situational Awareness (SiA)

• a person’s awareness of what is going on in her surroundings,the meaning of these surroundings, and using this informationto decide and act.

SiA in numbers• Big market share of USD 32,6 billion by 2022 [Allied Market Research]

Situational Aware CPS• In ICT terms:

• Sensed data, • received from IoT devices interacting in a prescribed open or closed

physical space, • used to observe the (user’s) surroundings and make detailed assessments

about his environment.

12Overall: decision making- Which solution is more e.g. energy efficient?

- Which architecture decisions may limit the amount of data created, transferred, and analyzed?

- Which communication topology to use? Cyber Physical Space
