Digitransit (project page)

HSL's next-generation journey planner, in cooperation with Finnish Transport Agency's national Journey.fi.

Digitransit project includes digitransit-ui user interface and back-end services providing APIs for public transportation data, geocoding and maps.


Live maps

Most vehicles in the HSL area publish their status to a MQTT server. MQTT clients can subscribe to these status messages and filter them based on e.g. transport mode and geographical area.
