NAME
efa - Command line client for EFA-based public transit routing services
SYNOPSIS
efa --from city stop --to city stop [ additional options ]
efa [ options ] from-city from-stop [ via-city via-stop ] to-city to-stop
VERSION
version 2.24
DESCRIPTION
efa is a command line client for EFA-based public transit routing interfaces, e.g. <http://efa.vrr.de>.
efa requests connections between two points and displays the results.
By default, the EFA service at <http://efa.vrr.de> (operated by Verkehrsverbund Rhein-Ruhr) is used,
which supports most places in Germany. A list of all supported EFA instances can be retrieved with -l
and a custom instance can be selected using -s service or -u url. It is also possible to probe all known
EFA services for a specific connection using the -A and -D options.
If available, efa shows the expected occupancy of each route part. It ranges from "[ ]" (low occupancy)
to "[!!]" (very high occupancy). Occupation data appears to be limited to certain VRR trains at the
moment.
OPTIONS
--from city stop
Departure place
--to city stop
Arrival place
--via city stop
Travel via this place
In all cases, if you want stop to be an address or "point of interest", you can set it to
'addr:something' or 'poi:something'.
-a|--arrive hh:mm
Journey end time (overrides --time/--depart)
-A|--auto-url|--discover-and-print
Probe all known EFA entry points for the specified connection. Print the first result which was not
an error.
Note that this may take a while and will not necessarily return the best result. Also, using this
option by default is not recommended, as it puts EFA services under considerable additional load.
-b|--bike
Request connections allowing the passenger to take a bike with them. Note that this may cause efa to
display no routes at all -- In that case, the backend was unable to find such connections or didn't
know about their bike-support.
-B|--bike-info
Show information about bike support, but do not select routes based on it. In essence, this option
simply changes the --ignore-info default. It is useful when --bike did not return any routes even
though most of the route has bike support.
-d|--date dd.mm.[yyyy]
Journey date. Also accepts the shortcut tomorrow.
-D|--discover
Probe all known EFA entry points for the specified connection. No routes are returned in this case.
Instead, efa will print the URLs and names of all entry points which did not return an error.
-u|--efa-url url
URL to the EFA entry point, defaults to <https://app.vrr.de/vrrstd/XML_TRIP_REQUEST2>. Depending on
your location, some urls may contain more specific data than others. See
Travel::Routing::DE::EFA(3pm) and the -l option for alternatives.
-e|--exclude transports
Exclude transports (comma separated list).
Possible transports: zug, s-bahn, u-bahn, stadtbahn, tram, stadtbus, regionalbus, schnellbus,
seilbahn, schiff, ast, sonstige
-E|--extended-info
Display more than just the basic route information. At the moment, the following is displayed (if
available):
• Route duration
• Ticket fare
• transfer duration and elevation changes (via stairs / escalators) at each stop
-f|--full-route
Display intermediate stops (with time and platform) of each train. Note that these are not always
available.
-I|--ignore-info [ regex ]
Ignore additional information matching regex (default: /Fahrradmitnahme|Einstiegshilfe/)
If regex is not supplied, removes the default regex (-> nothing will be ignored)
-i|--include type
Include connections using trains of type type, where type may be:
• local (default)
only take local trains ("Verbund-/Nahverkehrslinien"). Slow, but the cheapest method if you're
not traveling long distance
• ic
Local trains + IC
• ice
All trains (local + IC + ICE)
-l|--list
List supported EFA services with their URLs (see -u) and abbreviations (see -s).
-M|--maps
Output links to maps of transfer paths and transfer stations where available.
-m|--max-change number
Print connections with at most number interchanges
-n|--num-connections number
Return up to number connections. If unset, the default of the respective EFA server is used (usually
4 or 5).
-P|--prefer type
Prefer connections of type:
• speed (default)
The faster, the better
• nowait
Prefer connections with less interchanges
• nowalk
Prefer connections with less walking (at interchanges)
-p|--proximity [minutes]
Take stops close to the stop/start into account. By default, up to 10 minutes of walking to/from the
route's first/last stop is considered acceptable. You can specify minutes to use a custom value.
-s|--service name
Shortname of the EFA entry point. See Travel::Routing::DE::EFA(3pm) and the -l option for a list of
services.
-t|--time|--depart hh:mm
Journey start time
--timeout seconds
Set timeout for HTTP requests. Default: 60 seconds.
-v|--version
Print version information
-w|--walk-speed speed
Set your walking speed to speed. Accepted values: normal (default), fast, slow
-x|--accessibility types
Request connections satisfying all of the specified accessibility types (comma-separated list, option
may be repeated). Please note that this may cause the backend to return no results at all, either
because no such connection exists or because the required lines do not have the correct accessibility
attributes set.
The following types are supported:
e / no-escalators
Transfers must be possible without taking an escalator.
E / no-elevators
Transfers must be possible without using an elevator.
i / info
Does not restrict the requested connections. However, this option causes efa to display
additional accessibility information for each route part (where available). When -x w or -x l do
not return any connections, using -x i might be more helpful (though it cannot guarantee that any
of the results satisfy the respective type).
l / nf / low-platform
All vehicles must be low-platform ("Niederflur").
s / no-stairs
Transfers must be possible without stairs (e.g. via escalators/elevators or ramps).
w / wheelchair
All vehicles must be wheelchair accessible.
EXIT STATUS
0 Everything went well
1 Invalid arguments, see error message
2 Network error, unable to send request
3 EFA did not return any parsable data
4 EFA error: ambiguous input
5 EFA error: no connections found
10 Unknown Travel::Routing::DE::EFA error
255 Other internal error
CONFIGURATION
None.
EXAMPLES
efa Do Hbf MH Hbf
Look up a connection from Dortmund (Do) Hbf to Muelheim (MH) Hbf
efa --include ice Essen Hbf Hamburg Dammtor
Look up a connection with long-distance trains
efa --arrive 18:00 -e zug,s-bahn -M E Wickenburgstr D Oststr
Look up a connection from Essen Wickenburgstr to Duesseldorf Oststr. Do not use any trains, make
sure to arrive around 18:00 and print links to maps of all interchange stations.
efa -s vvs Stuttgart Hbf Stuttgart Marienplatz
Use the VVS (Verkehrsverbund Stuttgart) EFA service to look up a connection.
DEPENDENCIES
This script requires perl 5.10 (or higher) with the following modules:
• Class::Accessor
• Exception::Class
• LWP::UserAgent
• XML::LibXML
BUGS AND LIMITATIONS
The EFA backend is not able to calculate "two-way" routes, i.e. from -> via -> to routes with from == to.
If from and to are the same stop, it doesn't even try to calculate a route ("we recommend walking
instead"), if they are close to each other it may or may not work. Workaround: Request from -> via using
the normal four-argument efa invocation, read the time, use efa -t time via via to to to request via ->
to.
