DESCRIPTION

Travel::Routing::DE::VRR is a client for the efa.vrr.de web interface. You pass it the start/stop of your journey, maybe a time and a date and more details, and it returns the up-to-date scheduled connections between those two stops.

It uses LWP::UserAgent and XML::LibXML for this.

METHODS

$efa = Travel::Routing::DE::VRR->new(%opts)

Returns a new Travel::Routing::DE::VRR object and sets up its POST data via %opts.

Valid hash keys and their values are:

origin => [ city, stop [ , type ] ]

Mandatory. Sets the start of the journey. type is optional and may be one of stop (default), address (street and house number) or poi ("point of interest").

destination => [ city, stop [ , type ] ]

Mandatory. Sets the end of the journey, see origin.

via => [ city, stop [ , type ] ]

Optional. Specifies an intermediate stop which the resulting itinerary must contain. See origin for arguments.

arrival_time => HH:MM

Journey end time

departure_time => HH:MM

Journey start time. Default: now

date => DD.MM.[YYYY]

Journey date. Default: tdoay

exclude => \@exclude

Do not use certain transport types for itinerary. Accepted arguments: zug, s-bahn, u-bahn, stadtbahn, tram, stadtbus, regionalbus, schnellbus, seilbahn, schiff, ast, sonstige

max_interchanges => num

Set maximum number of interchanges

select_interchange_by => speed|waittime|distance

Prefer either fast connections (default), connections with low wait time or connections with little distance to walk

use_near_stops => 0|1

If true: Try using near stops instead of the specified origin/destination ones

train_type => local|ic|ice

Include only local trains into itinarery (default), all but ICEs, or all.

The latter two are usually way more expensive for short routes.

walk_speed => slow|fast|normal

Set walk speed. Default: normal

with_bike => 0|1

If true: Prefer connections allowing passengers with bikes

lwp_options => \%hashref

Options to pass to LWP::UserAgent->new.

submit => 0|1

By default, new will create a POST request and submit it to http://efa.vrr.de. If you do not want it to be submitted yet, set this to 0.

$efa->submit(%opts)

Submit the query to http://efa.vrr.de. %opts is passed on to LWP::UserAgent->new.

$efa->routes()

Returns a list of Travel::Routing::DE::VRR::Route(3pm) elements. Each one contains one method of getting from start to stop.

The following methods act like the arguments to new. See there.

$efa->departure_time($time)

$efa->arrival_time($time)
