NeTEx
NeTEx (formally Network Timetable Exchange ''PD CEN/TS 16614-1:2014', PD CEN/TS 16614-2:2014 and PD CEN/TS 16614-3:2014'') is the CEN Technical standard for exchanging Public Transport Information as XML documents. 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, ...

Transmodel
Transmodel, also known as Reference Data Model For Public Transport (EN 12896), is a European Standard for modelling and exchanging public transport information. It provides a standard data model and specialised data structures to uniformly represent common public transport concepts, facilitating the use of data in a wide variety of public transport information systems, including for timetabling, fares, operational management, real-time data, and journey planning. As of 2021, the current version of Transmodel is 6.0. Scope Transmodel provides a comprehensive conceptual model for public transport information systems, covering multiple subdomains including transport network infrastructure and Geospatial topology, topology, schedules, Journey Planner, journey planning, fares, fare validation, real-time passenger information, and operational systems.

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 Mode of transport, 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 bicycle, cycling, Car, 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 ope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Committee For Standardization
The European Committee for Standardization (CEN, ) 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 Telecommunications Standards Institute (ETSI).

Public Transport
Public transport (also known as public transit, mass transit, or simply transit) are forms of transport available to the general public. It typically uses a fixed schedule, route and charges a fixed fare. There is no rigid definition of which kinds of transport are included, and air travel is often not thought of when discussing public transport—dictionaries use wording like "buses, trains, etc." Examples of public transport include Public transport bus service, city buses, trolleybuses, trams (or light rail) and Passenger rail transport, passenger trains, rapid transit (metro/subway/underground, etc.) and ferry, ferries. Public transport between cities is dominated by airlines, intercity bus service, 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 set embarkation/disembarkation points to a prearranged timetable, with the most frequent services running to a headwa ...

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 netwo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Topology
Topology (from the Greek language, Greek words , and ) is the branch of mathematics concerned with the properties of a Mathematical object, geometric object that are preserved under Continuous function, continuous Deformation theory, deformations, such as Stretch factor, stretching, Torsion (mechanics), twisting, crumpling, and bending; that is, without closing holes, opening holes, tearing, gluing, or passing through itself. A topological space is a Set (mathematics), set endowed with a structure, called a ''Topology (structure), topology'', which allows defining continuous deformation of subspaces, and, more generally, all kinds of List of continuity-related mathematical topics, continuity. Euclidean spaces, and, more generally, metric spaces are examples of topological spaces, as any distance or metric defines a topology. The deformations that are considered in topology are homeomorphisms and Homotopy, homotopies. A property that is invariant under such deformations is a to ...

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. MDE is a subfield of a software design approach referred as round-trip engineering. The scope of the MDE is much wider than that of the Model-Driven Architecture. 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 m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 European Committee for Standardization, 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. * ...

GTFS
GTFS, or the General Transit Feed Specification, defines a common data 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 or GTFS Schedule 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 got into contact with Google and provided th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RailML
railML (Railway Markup Language) is a proprietary freeware XML Schema-based data exchange format for data interoperability of railway applications. Motivation The growing number of computer applications modeling different aspects of railway operations, with different operators developing separate solutions parallelly, bore a chronic difficulty of connecting different railway IT applications. The exchange of data for operation concepts, slot management, simulation or infrastructure planning, etc. was possible either by hand or with a lot of special developed interfaces with loss of time and cost problems for railway companies. If there are ''n'' applications that are supposed to exchange data, with a special interface for each pair of programs respectively, \frac interfaces are required—only one, if ''n=2'', but 10, if ''n=5''—increasing the complexity above average. This problem can be mitigated by means of enterprise application integration with a single, universal exchang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
