Over the past decade Distributed Journey Planning has been shown in three European systems to provide a way to extend the range of local or regional public transport information systems to cover much wider geographical areas. So the experience of the UK’s JourneyWeb, the German DELFI and the north European EU-Spirit systems have been brought together to develop an Open API for distributed journey planning, based on an extension of the German TRIAS schema.

This work has created a European (CEN) Technical Specification entitled “Intelligent transport systems - Public transport - Open API for distributed journey planning”. This has now been approved, and has been published as CEN/TS 17118:2017. It should be available through all European national Standards bodies.

This page provides access to the latest Schema XSD files to facilitate work by those wishing to implement the standard described in the published Technical Specification.
