[2] Following on from a successful prototype one-number travel service developed by Lancashire County Council in 1999, the national Traveline organisation was established in 2000.

[3] A prototype national door-to-door journey for Great Britain (i.e. UK without Northern Ireland) - using the Lancashire Traveline model for regional journey planners - was available for evaluation by 'stakeholders and key opinion formers' by November 2003, and the service was officially launched by Secretary of State for Transport Alistair Darling on 31 December 2004.

[6] Details of all bus stops in the country are assembled into the National Public Transport Access Nodes database (NaPTAN) which is updated daily.

The organisation also maintains the associated National Public Transport Gazetteer of all place names, both formal and informal, that may be used to indicate the destination for a requested journey.
