The story

Founding

HSL was founded on 1 January 2010 on the basis of the Finnish public transportation law, joukkoliikennelaki, which was adopted on 3 December 2009. According to joukkoliikennelaki, HSL is responsible for the planning of public transportation in Greater Helsinki. The traffic functions of the inter-municipal Helsinki Metropolitan Area Council (YTV) and planning, procuring and tendering functions of Helsinki City Transport (HKL, within the city of Helsinki) were moved into the transport authority.

When it was founded, HSL had a revenue of over €500 million and approximately 350 employees.

Digitransit

In 2016, HSL started to develop a new version of its native journey planner, Reittiopas, originally released by YTV in 2001. The replacement intermodal public transport route planner, called Digitransit, is built on the open source OpenTripPlanner. Digitransit has been adopted by most public transport providers in Finland, and also by the pan-Estonian journey planner, the German cities of Herrenberg, Ludwigsburg, Aachen and Pforzheim, and the Embark transit authority in Oklahoma City.
