Identification of Fixed Objects in Public Transport
IFOPT (Identification of Fixed Objects in Public Transport) is a prCEN Technical Specification that provides a Reference Data Model for describing the main fixed objects required to describe public access to Public Transport (e.g. airports, stations, bus stops, ports, points of interest, entrances, etc.). Such models are a fundamental part of the ublic transport information systems needed both to operate public transport and to inform passengers about services.
Scope
IFOPT defines a model and identification principles for Stop Places for all modes of transport (including airports, stations, ports, bus stops, coach stations, taxi ranks, etc). It distinguishes all points of access to transport as Quays and also other areas of an interchaneg such as booking halls, concourses, waiting rooms, etc. It describes the navigation paths between such points allowing the routing by journey planners. It can incldue detailed accessibility data about access for wheelchair users, the visually impaired, etc. It can also represent likely points of delay due to processes such as checkin, securty, etc.
IFOPT is itself built upon the CEN Transmodel standard and defines four related sub models.
- Stop Place Model: Describes the detailed structure of a Stop Place (that is station, airport, etc providing a point of access to public transport) including physical points of access to vehicles and the paths between the points, including accessibility.
- Point of Interest Model: Describes the structure of a Point Of Interest (that is tourist attractions, Public facilities' etc) to which people may wish to travel by public transport) including physical points of access, i.e. ENTRANCEs.
- Gazetteer Topographical Model: Provides a topographical representation of the settlements (cities, towns, villages etc) between which people travel. It is used to associate Stop and Station elements with the appropriate topographic names and concepts to support the functions of journey planning, stop finding, etc.
- Administrative Model. Provides an organisational model for assigning responsibility to create and maintain data as a collaborative process involving distributed stakeholders. Includes namespace management to manage the decentralised issuing of unique identifiers.
