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 for public access to Public Transport (e.g. airports, stations, bus stops, ports, points of interest, entrances, etc.). Such a model is a fundamental part of the modern public transport information systems needed both to operate public transport and to inform passengers about services.

Scope

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 stations, airports, ferry ports, bus stops, coach stations, etc, providing a point of access to public transport) including Entrances, pathways, and accessibility limitations.
  • Point of Interest Model: Describes the structure of a Point Of Interest (that is tourist attractions, leisure facilities, stadia, public buildings, parks, prisons, 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.

Stop Places

The Stop Place model defines a conceptual model and identification principles for places of access (Stop Places) for all modes of transport (including airports, stations, ports, bus stops, coach stations, taxi ranks, etc).

  • It distinguishes all physical points of access to transport such as platforms, gates, quays, bays, stances, taxi ranks, and also other areas of an interchange such as booking halls, concourses, waiting rooms, etc.
  • It describes the navigation paths between such points allowing the routing by journey planners.
  • It can represent detailed accessibility data about access for wheelchair users, the visually impaired, and other categories of users with special needs, etc.
  • It can also represent likely points of delay due to processes such as checkin, security, etc.
  • elements can be assigned the names, labels and codes needed to identify them to the public in different contexts.
