Semantics of a connection #1

Closed pietercolpaert closed 10 years ago

pietercolpaert commented 10 years ago

Fictive example:

If I take the train from Berlin → Paris, I might cross Brussels first. In Brussels I have a 10 minute walk towards my next ride.

What do you call a "connection"? The walk from stop_point A towards stop_point B? Or is the connection the trip from Berlin → Brussels and a second one from Brussels → Paris?

How is this done in transmodel? I know Hafas uses the second option.

Would "transfer" cover the semantics in a better way?

l-vincent-l commented 10 years ago

I don't really an opinion about that. In transmodel the exact term is CONNECTION LINK, so we dropped the link. (http://sitp.transmodel.org/transmodel_v5_en/pages/9facaa1b3a8a02ec.htm)

In the abstract of H Bast 2010 (http://dl.acm.org/citation.cfm?id=1888969) it said : transfer pattern, i.e., the sequence of stations where a change of vehicle occurs; (2) direct connections without change of vehicle

Both are used ...

I’m in favor of using the transmodel vocabulary as much as possible, thus connection link

pietercolpaert commented 10 years ago

So it becomes connection_link?

Changed to connection_link in development branch. Will get in master if no further objections.
