ISO DIS 17185-1

Description / Abstract: The purpose of this international standard is to define framework for the realization of efficient public transport user information provision to surface public transport users including international worldwide travelers by defining basic framework for surface public transport user information provisions.

In the surface public transport user information provision area, a set of regional and national standards have already been established by related regional and national standardizing bodies.

This international standard defines basic framework for user information provision for surface public transport users, from the viewpoint that the surface public transport users should be provided with proper static and real time information when it is most desired and effective. In order to realize the desi rable information provision, surface public transport information has to be efficiently gathered, processed and provided to surface public transport users in an appropriate way by using currently available regional standards.

This international standard is not aiming to define new international standards that supersede current regional and national standards related to surface public transport but is aiming to define the basic framework of surface public transport user information provision by esteeming existing regional standards and wisely using them.

This international standard is not aiming to define specific information interfaces such as data format or a stop point numbering system and etc but currently available regional standards established by regional and national groups are suggested to be applied in that scope.

This international standard is composed of following three parts:

- Part 1: Standards framework for public information systems

- Part 2: Data and Interface standards catalogue and cross reference

- Part 3: Use cases for journey planning systems and their inter-operation
