It provides a W3C XML schema based on the Transmodel abstract model of common public transport concepts and data structures and can be used to exchange many different kinds of data between passenger information systems, including data describing for stops, facilities, timetabling and fares. Such data can be used by both operational management systems and customer facing systems for journey planning etc. Scope NeTEx provides a modular XML schema for public transport information data including passenger information systems, with coverage of a number of different subdomains of PT information, including transport network infrastructure and topology, public transport schedules, journey planning, fares, fare validation. It includes uniform mechanisms for version ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Service Interface For Real Time Information
The Standard Interface for Real-time Information or SIRI is an XML protocol to allow distributed computers to exchange real-time information about public transport services and vehicles. The protocol is a CEN norm, developed originally as a technical standard with initial participation by France, Germany (Verband Deutscher Verkehrsunternehmen), Scandinavia, and the UK ( RTIG) SIRI is based on the CEN Transmodel abstract model for public transport information, and comprises a general purpose model, and an XML schema for public transport information. A SIRI White Paper is available for further information on the protocol. Scope CEN SIRI allows pairs of server computers to exchange structured real-time information about schedules, vehicles, and connections, together with informational messages related to the operation of the services. The information can be used for many different purposes, for example: *To provide real-time departure from stop information for display on stops, i ...

Journey Planner
A journey planner, trip planner, or route planner is a specialized search engine used to find an optimal means of travelling between two or more given locations, sometimes using more than one transport mode. Searches may be optimized on different criteria, for example ''fastest'', ''shortest'', ''fewest changes'', ''cheapest''. They may be constrained, for example, to leave or arrive at a certain time, to avoid certain waypoints, etc. A single journey may use a sequence of several modes of transport, meaning the system may know about public transport services as well as transport networks for private transportation. Trip planning or journey planning is sometimes distinguished from ''route planning'', which is typically thought of as using private modes of transportation such as cycling, driving, or walking, normally using a single mode at a time. Trip or journey planning, in contrast, would make use of at least one public transport mode which operates according to published sched ...

Identification Of Fixed Objects In Public Transport
IFOPT (''Identification of Fixed Objects in Public Transport'') is a CEN Technical Specification that provides a Reference Data Model for describing the main fixed objects required for public access to Public transport, that is to say Transportation hubs (such as airports, stations, bus stops, ports, and other destination places and points of interest, as well as their entrances, platforms, concourses, internal spaces, equipment, facilities, accessibility etc.). Such a model is a fundamental component 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 ...

European Committee For Standardization
The European Committee for Standardization (CEN, french: Comité Européen de Normalisation) is a public standards organization whose mission is to foster the economy of the European Single Market and the wider European continent in global trading, the welfare of European citizens and the environment by providing an efficient infrastructure to interested parties for the development, maintenance and distribution of coherent sets of standards and specifications. The CEN was founded in 1961. Its thirty-four national members work together to develop European Standards (ENs) in various sectors to build a European internal market for goods and services and to position Europe in the global economy. CEN is officially recognized as a European standards body by the European Union, European Free Trade Association and the United Kingdom; the other official European standards bodies are the European Committee for Electrotechnical Standardization ( CENELEC) and the European Telecommunic ...

Public Transport
Public transport (also known as public transportation, public transit, mass transit, or simply transit) is a system of transport for passengers by group travel systems available for use by the general public unlike private transport, typically managed on a schedule, operated on established routes, and that charge a posted fee for each trip. There is no rigid definition; the '' Encyclopædia Britannica'' specifies that public transportation is within urban areas, and air travel is often not thought of when discussing public transport—dictionaries use wording like "buses, trains, etc." Examples of public transport include city buses, trolleybuses, trams (or light rail) and passenger trains, rapid transit (metro/subway/underground, etc.) and ferries. Public transport between cities is dominated by airlines, coaches, and intercity rail. High-speed rail networks are being developed in many parts of the world. Most public transport systems run along fixed routes with s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passenger Information System
A passenger information system, or passenger information display system, is an automated system for supplying users of public transport with information about the nature and the state of a public transport service through visual, voice or other media. It is also known as a customer information system or an operational information system. Among the information provided by such systems, a distinction can be drawn between: * Static or schedule information, which changes only occasionally and is typically used for journey planning prior to departure. * Real-time information, derived from automatic vehicle location systems and changes continuously as a result of real-world events, which is typically used during the course of a journey (primarily how close the service is running to time and when it is due at a stop, as well as incidents that affect service operations, platform changes, etc.). Static information has traditionally been made available in printed form though route netw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Topology
In mathematics, topology (from the Greek words , and ) is concerned with the properties of a geometric object that are preserved under continuous deformations, such as stretching, twisting, crumpling, and bending; that is, without closing holes, opening holes, tearing, gluing, or passing through itself. A topological space is a set endowed with a structure, called a '' topology'', which allows defining continuous deformation of subspaces, and, more generally, all kinds of continuity. Euclidean spaces, and, more generally, metric spaces are examples of a topological space, as any distance or metric defines a topology. The deformations that are considered in topology are homeomorphisms and homotopies. A property that is invariant under such deformations is a topological property. Basic examples of topological properties are: the dimension, which allows distinguishing between a line and a surface; compactness, which allows distinguishing between a line and a circle; co ...

Model Driven Design
Model-driven engineering (MDE) is a software development methodology that focuses on creating and exploiting domain models, which are conceptual models of all the topics related to a specific problem. Hence, it highlights and aims at abstract representations of the knowledge and activities that govern a particular application domain, rather than the computing (i.e. algorithmic) concepts. Overview The MDE approach is meant to increase productivity by maximizing compatibility between systems (via reuse of standardized models), simplifying the process of design (via models of recurring design patterns in the application domain), and promoting communication between individuals and teams working on the system (via a standardization of the terminology and the best practices used in the application domain). For instance, in model-driven development, technical artifacts such as source code, documentation, tests, and more are generated algorithmically from a domain model. A modeling p ...

TransXChange
TransXChange is a UK national XML based data standard for the interchange of bus route and timetable information between bus operators, the Vehicle and Operator Services Agency, local authorities and passenger transport executives, and others involved in the provision of passenger information. The format is a UK national de facto standard sponsored by the UK Department of Transport. The standard is part of a family of coherent transport related XML standards that follow UK GovTalk guidelines and are based on the CEN Transmodel conceptual model. Although TransXChange is currently used mainly to exchange bus timetables, it may also be used for schedules for rail and other modes. History TransXChange is intended as a successor to the widely used ATCO-CIF format for bus timetables and was developed as a modernised representation of ATCO-CIF content, using an XML representation based on the Transmodel Reference model for Public Transport. * Version 1.0 versions of TransXchange ...

GTFS
GTFS, which stands for General Transit Feed Specification or (originally) Google Transit Feed Specification, defines a common format for public transportation schedules and associated geographic information. GTFS contains only static or scheduled information about public transport services, and is sometimes known as GTFS Static to distinguish it from the GTFS Realtime extension, which defines how information on the realtime status of services can be shared. History What was to become GTFS started out as a side project of Google employee Chris Harrelson in 2005, who “monkeyed around with ways to incorporate transit data into Google Maps when he heard from Tim and Bibiana McHugh, married IT managers at TriMet, the transit agency for Portland, Oregon”. McHugh is cited with being frustrated about finding transit directions in unfamiliar cities, while popular mapping services were already offering easy-to-use driving directions at the time. Bibiana and Tim McHugh eventually go ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
