Transport for London has opened up its website to software developers to allow them to build mashups using its transport information.
Information about London's Tubes, buses and river services is being made available online so that web developers can use it to create products such as mobile phone apps that help passengers, TfL said.
The freely available application programming interfaces, available through TfL's Developers' Area site, allows web developers to access a number of data sets and feeds to live London Underground/Tube travel news on London's Datastore.
TfL will also provide data such as planned weekend Tube works, station locations (for the Tube, Docklands Light Railway and London Overground), River Thames pier locations, find-a-ride (licensed private hire operators) and Oyster Ticket Stop locations
Chris MacLeod, TfL's director of group marketing, said, "We want to harness the innovative ideas in the developer community to provide improved information which will benefit all transport users. Therefore it is vital that Transport for London provides transparent information to the public and allows developers to use data to create smart-technology solutions."
