about the usage of open source tools for the smart mobility in the Piedmont Region Infomobility services in Piedmont region are backed by open source tools since 2014. OpenTripPlanner routing engine was originally adopted for a bicycle planning service and then extended to a multimodal service for the whole region. The web app www.muoversiatorino.it, designed and developed by 5T in 2017, leverages the Digitransit platform, which adds to OTP more functionalities like RT predictions and vehicle monitoring.

5. OSM
OpenStreetMap is a collaborative project to create a free editable map of the world,
established in 2004. This crowdsourced data is made available under the Open Database
License.
OSM is the wikipedia of maps
Why use OSM?
• Anyone can improve the map
• It collects any features type (e.g. POI, streets, fire extinguisher, parks, speed limit)
• Many tools available to analyze data
• Data search and extraction

6. OSM data in OTP
● Names & geometry
● Directionality & turn restriction
● Car and bike parks
● Road classification for speed
calculation
● Bike safety model
● Wheelchair accessibility
● Area routing

7. OSM extracts
Free regional geospatial data:

8. The General Transit Feed
Specification defines a
common format for public
transportation schedules and
associated geographic
information
Information about:
● Agencies
● Routes
● Stops
● Calendars
● Shapes
● Timetables
