1 Scope The purpose of this part of ISO 17185 is to define high level general requirements of journey planning systems by standardizing use cases. This part of ISO 17185 defines basic requirements for implementing the journey planning system, from the viewpoint that the public transport users should be provided with convenient tool to make his or her journey more efficient ones.

ISO 17185 is composed of the following parts:

• — Part 1: Standards framework for public information systems: (International Standard)
• — Part 2: Data and Interface standards catalogue and cross reference: (Technical Report)
• — Part 3: Use cases for journey planning systems and their inter-operation: (Technical Report)
