Editing Bus stop (section)

===Data model===
Modern [[passenger information system]]s and [[journey planner]]s require a detailed digital representation of stops and stations. The [[European Committee for Standardization|CEN]]  [[Transmodel]] data model, and the related [[IFOPT]] data interchange standard, define how transport systems, including bus stops, should be described for use in computer models. In Transmodel, a single bus stop is modeled as a "Stop Point", and a grouping of nearby bus stops as a "Stop Area" or "Stop Place". The [[General Transit Feed Specification]] (GTFS) standard, originally developed by [[Google]] and [[TriMet]],<ref>{{Cite web|url=http://beyondtransparency.org/chapters/part-2/pioneering-open-data-standards-the-gtfs-story/|title=Pioneering Open Data Standards: The GTFS Story|website=beyondtransparency.org|access-date=2017-05-11}}</ref> defines a simple and widely used data interchange standard for public transport schedules. GTFS also includes a table of stop locations which for each stop gives a name, identifier, location, and identification with any larger station that the stop may be a part of.<ref>{{Cite web|url=https://developers.google.com/transit/gtfs/reference/stops-file|title=stops.txt File {{!}} Static Transit {{!}} Google Developers|website=Google Developers|language=en|access-date=2017-05-11}}{{Dead link|date=July 2020 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>  [[OpenStreetMap]] also has a modelling standard for bus stops.<ref>{{cite web|url=https://wiki.openstreetmap.org/wiki/Bus_stop|title=Bus Stop|website=OpenStreetMap|access-date=2010-03-25}}</ref>

The United Kingdom has collected a complete database of its public transport access points, including bus stops, into the [[NaPTAN|National Public Transport Access Nodes (NaPTAN)]] database with details of 350,000 nodes and which is available as [[open Data]] from [[data.gov.uk]].<ref>{{cite web|url=http://data.gov.uk/node/8473|title=National Public Transport Access Nodes (NaPTAN)|publisher=[[data.gov.uk]]|url-status=dead|archive-url=https://web.archive.org/web/20100325144902/http://data.gov.uk/node/8473|archive-date=2010-03-25}}</ref> In this database, developed by the Department of Transport in 2001, stops are classified as "marked"  or "custom and usage" (i.e. unmarked stops where the driver will stop the vehicle on request). Use of marked stops varies: either the bus will always stop, or will stop by request only.
