Planning Public Transportation - Oslo Metro
[3.2] Published XX. November 2021.[ Introduction | Oslo Metro | Oslo Tram | Bergen | Summary | {{PART-6}} | {{PART-7}} | {{PART-8}} ]
The Oslo Metro Network
The Oslo Metro Network has 5 lines, which all share a common section trough the city centre. The northern connection between the line to Sognsvann (in the west) and the line to Vestli (in the east) is relatively new, and has added extra complexity to the planning and operation of the metro.
Route 1: Frognerseteren - Helsfyr (- Bergkrystallen)
This route has a part time extension from Helsfyr to Bergkrystallen, and it has a stop that is only used in one direction (Gulleråsen, towards Frognerseteren only).We start with a text file defining the route, with stops and travel time between them. Note that the comments (in red, and explained below) are not part of the file. The filename extension «.def» is mandatory:

[1] Lines starting with # are ignored by the
program. Use them to add comments to help a person reading the file.
[2] The route number on this line is just a comment. The number in the file name is also just a comment (so to speak). We'll get back to the route number later on.
[3] This is the first stop on the route, in the first direction (which is Down). The next row is the next stop, and so on. The second direction (Up), starts at the bottom. The columns, which are separated by one or more spaces, are:
Stop ID
OS415 A A:3 Bergkrystallen
A unique identifier for each stop, consisting of two uppercase letters and three digits.
The letters used here is «OS» which is short for «Oslo». I have numbered the stops sequentially from the city centre (Stortinget) outwards.
Platform in the Down direction
OS491 A A:3 Bergkrystallen
Platforms are indicated by a single uppercase letter. I have chosen «A» for the direction to the city centre, and «B» outwards from it.
[4] The travel time in minutes to the current stop (from the previous one) is 1, unless given explicitly after a colon:
OS412 A:2 B Karlsrud
Legal values are «0», «0.5», «1», «1.5» and so on. Do not use values larger than «59» (as the program does not handle such values very well).
Platform in the Up direction
OS412 A:2 B Karlsrud
As above. Start reading from the bottom of the list.
[5] Stops in only one direction are supported; specify
- (a minus sign) instead of the platform identifier:
OS430 B - Gulleråsen
Stop name
OS412 A A:3 Bergkrystallen
The first character in the name must be a letter. The name may contain spaces, as shown for this fictitious stop:
LN123 A:2 B Oxford Circus
Then we need a setup file. I have given it the «.setup» filename extension, but this is just a suggestion.
File: oslo-metro/metro-1.setup
## Networkplanner ## # [1]
# [2]
route add 1 file:oslo-metro/01.def down:2 up:13 interval:15 # [3]
summary # [4]
[1] The first row must contain the following string:
## Networkplanner ##
[2] Empty rows are ignored.
[3] Use the «route» command to set up a new route. This command can be used several times, thus setting up a network of routes.
The first part tells the program to set up a route:
route 1 file:oslo-metro/01.def down:2 up:13 interval:15
The next part is the route number. Note that any value in the file itself (on a comment row), and part of the filename, are not used.
route add 1 file:oslo-metro/01.def down:2 up:13 interval:15
The rest of the row is a list of colon separated values, in any order. The first one here is the filename for the route specification file (as shown above):
route add 1 file:oslo-metro/01.def down:2 up:13 interval:15
Then we have the offset value in minutes for the departures in the Down direction. Legal values are «0», «0.5», »1» and so on. The first departure will start at 0 minutes past the hour if this is not set.
route add 1 file:oslo-metro/01.def down:2 up:13 interval:15
As above, for the Up direction:
route add 1 file:oslo-metro/01.def down:2 up:13 interval:15
And finally the interval between departures, again in minutes. Legal values are «0.5», »1» and so on. The default value is 10 minutes.
route add 1 file:oslo-metro/01.def down:2 up:13 interval:15
[4] Save the summary (as shown below) with the «summary» command. The summary will be printed to the screen:
summary
Specify a file, if you want the output to be saved instead of printed to the screen. The filename must have the «.txt» extension. This command will overwrite an existing file, if any
summary oslo-metro/summary.txt
The special filename «-» (a minus sign) can also be used to print the summary to the screen.
summary -
Run the comamnd from the directory you unapcked the zip file in, e.g. «/home/arne/public-transportation«:
$ ./networkplanner oslo-metro/metro-1.setup
The first half of the result, the Down direction, looks like this:

It compares favourably with the official timetable (albeit with selected stops only), the first gray area:
The second half of the result, the Up direction, looks like this:

58 | 11 26 41 56 Bergkrystallen [B]
This part also compares favourably with the official timetable:
Let us see how many vehicles we need to run the route every fifteen minues.
First we have to tell the program how to combine the routes. This is easy, as we have hust one. But the program supports multiple routes, and differentiates between the directions as well:
File: oslo-metro/vehicles-1a.def
=0100 # [1]
1 D Bk/1;Bk 6 # [2]
1 U Frs/1;Frs 10 # [3]
[1] The series to place the vehicles in. Use four digits, with zeroes as the last two. The vehicles are numbered from «01» and upwards in the series.
[2] Start with route 1 in the Down direction. The third column is the text to show on the departure and arival rows. Specify a second text after a semicolon if you want a different text on the arrival rows.
[3] The next departure, this time on the same route and in the Up direction.
We have to change the setup file. Here is the modified version:
File: oslo-metro/metro-1a.setup
## Networkplanner ##
route add 1 file:oslo-metro/01.def down:2 up:13 interval:15
summary
vehicles oslo-metro/vehicles-1a.def # [1]
[1] A new vehicle definition file.
Then we can run the program with the new setup file:
$ ./networkplanner oslo-metro/metro-1a.setup
The number of vehicles is shown after the summary. Here it is:
0101 0102 0103 0104 0105 0106 0107 0108 0109
-------------------------------------------------------------------
Bk/1 dep 0002 0017 0032 0047 0102 0117 0132 0147 0202
Frs arr 0100 0115 0130 0145 0200 0215 0230 0245 0300
Frs/1 dep 0113 0128 0143 0158 0213 0228 0243 0258 0313
Bk arr 0211 0226 0241 0256 0311 0326 0341 0356 0411
Bk/1 dep 0217 0232 0247 0302 0317 0332 0347 0402 0417
0100: Number of vehicles: 9
---------------------------------------
Total number of vehicles: 9
The separate arrival and departure rows make it easy to see how much time is available at the route ends for turning the vehicle and so on.
Short Runnings to Helsfyr
Route 1 ends at Helsfyr, which has a two directional siding just east of the station, in the evenings:
We can reuse the existing route definition file for short runnings. Specify the first and/or last stop in the setup file:
File: oslo-metro/metro-1b.setup
## Networkplanner ##
route add 1 file:oslo-metro/01.def down:0 up:13 interval:15 start-at:OS406
summary
vehicles oslo-metro/vehicles-1b.def
The new vehicle definition file:
File: oslo-metro/vehicles-1b.def
=0100
1 D Hfy/1;Hfy 8
1 U Frs/1;Frs 10
Running it:
$ ./networkplanner oslo-metro/metro-1b.setup
The number of vehicles is shown after the summary. Here it is:
0101 0102 0103 0104 0105 0106 0107 0108
-------------------------------------------------------------

0100: Number of vehicles: 8
---------------------------------------
Total number of vehicles: 8
Just one vehicle saved compared with running all the way to Bergkrystallen. That is caused by the layover time at Helsfyr (which someone may say is excessive at 19 minutes). The alternative is 4 minutes, which really is too little to check that the metro set is empty, then drive to the siding, change direction, and drive to the other platform. But here we go:
File: oslo-metro/metro-1c.setup
## Networkplanner ##
route add 1 file:oslo-metro/01.def down:0 up:13 interval:15 start-at:OS406
summary
vehicles oslo-metro/vehicles-1c.def
=0100
1 D Hfy/1;Hfy 4
1 U Frs/1;Frs 10
Running it:
$ ./networkplanner oslo-metro/metro-1b.setup
We have saved one additional vehicle:
