Helsingin seudun liikenne -kuntayhtymä Digitransit – how to deploy 100% open journey planners 

Introducing HSL: Helsinki Regional Transport Authority HSL organises all bus, tram, subway and commuter train lines, ticketing and passenger information in the region. • 1.3 million citizens • 1 million boardings per day • 344 lines + citybike rental system 

HSL Journey Planner • People love our journey planner since 2001. • Open data and APIs since 2009. • Tens of mobile apps, mostly ”serverless”. 

Unoffical fan-made map of trunk lines 

Problems with closed map data • Costs: Use as little as possible. • Fragmented: Need to manually combine datasets. • Incomplete: Own additional dataset of walking paths. • Slow: Need to self-maintain, still out of date. • Inaccurate: Bad paths to stops (~8000) and addresses. • Inconsistent: Routing doesn’t match basemap. • Non-sharable: Consumers of data and APIs left without. 

Digitransit All your travel information integrated. 

100% open passenger information • Open data − Schedules in GTFS format − Vehicle positions, timetable estimates and service alerts − Addresses from OSM, OpenAddresses and Who’s On First − Street routing and basemap from OpenStreetMap • Open APIs − Raster tiles for basemap − Vector tiled data − GraphQL for flexible and efficient queries − MQTT for realtime data push 

100% open passenger information • Open source − Digitransit-ui using HTML5, React, Leaflet, Piwik, Sentry etc. − OpenTripPlanner 1.0 (contributed GraphQL API, airlines etc.) − Pelias (improvements for i18n, Finland l10n, QA tools) − OSM2VectorTiles (public transport improvements, fixes) − HSL map style based on OSM Bright − Docker deployment scripts • (HSL font and logo are not open.)

Itinerary 

Current coverage • Helsinki region instance provided by HSL • Finland provided by Finnish Transport Agency • Finnish cities in the works by Waltti travel card • Norway provided by Nasjonal Reiseplanlegger • South Tyrol, Italy provided by SASA • Tallinn, Estonia in the works as a EU project 

OpenTripPlanner • Multimodal combinations of walking/wheelchair, elevators, escalators, bicycle, citybike, car, public transport • Routing based on realtime data and elevation profile. • Routing configurable by many parameters. • Next generation, lighter codebase in the works as R5 (Rapid Realistic Routing on Real-world and Reimagined networks). 

Contributions to OSM via a use case • People want to go places taking advantage of public transport. − Public transport routing on OpenStreetMap.org front page to help how to get there, what route is best, realtime situation? • Raise awareness among government, cities, citizens, developers, consultants, IT students, researchers. • Bring new users and contributors for crowdsourced validation, especially routability, access, addresses. • Mapping and validation work by government 

Wishlist • Wider, more inclusive community − HOT-OSM! • Our own namespace − hsl_thinks:access=no • Clear separation of ODBL and government open data • Completion of goverment open data import in Finland • 3D editing of station indoor areas.
