City of Trento
● Capital of Trentino region (Italy)
● People: 120.000 (2017)
● Third largest city in the Alps;
second largest in the Tyrol
● Smartest mid-sized city in Italy (iCity Rate, 2017)

9. Analytics Use Case ‘Modal Split’

● Task: Given commute information captured on citizens’
smartphones + (geospatial) background knowledge,
detect the citizens’ transportation mode
● Detected modes can be aggregated → ‘Modal split’
● Distinctive patterns based on implicit spatial relations
(near, starts near, ends near, runs along, passes, is within, crosses, …)
○ Commute ran along a line feature of type Railway→ transportation mode is probably
‘train’
○ Commute started and ended near POI of type BusStop → transportation mode is
probably ‘bus’
○ …
