OpenBus shown in Figure 8 is an application developed using open big data. This application
approximates real time (geographical) positions of the city buses in all the routes in Trento, based
on published bus schedule and 2 minutes temporal snapshots of their registered geo-location. This
last dataset, as we write, is not publicly available yet because of technical reasons.

Figure 8: Open bus mobile app and livemap view of the real time simulation
It employs big data analytics tools and techniques in collecting, storing and analysing data
generated by on-board sensors to predict delays on the basis of the current position of the buses.
The API providing access to the real-time prediction and the associated mobile app are based on
17
the open source OneBusAway platform .
