Tokyo Metro Data

Data detailing Tokyo's Metro network, derived from the line plan and signs as well as tokyometro.jp.

You can help by improving it!

Data formats

JSON based data

Stations.json contains all currently known information. This includes the stations names in english and japanese as well all connections departing a station. Distances are in kilometers (float) and durations in seconds (int).

The following should explain stations.json:

{
    "lines": {
        ...
        "A": {
            "name_en": "Asakusa Line",
            "name_jp": "浅草線"
        },
        "C": {
            "name_en": "Chiyoda Line",
            "name_jp": "千代田線"
        },
        ...
    },
    "stations": {
        ...
        "E27": {
            "connections": [
                {
                    "distance": 0.6,
                    "duration": -1,
                    "target_id": "E26",
                    "type": "ride",
                    "type_id": 1
                },
                {
                    "distance": 0.8,
                    "duration": -1,
                    "target_id": "E28",
                    "type": "ride",
                    "type_id": 1
                },
                {
                    "distance": 0.0,
                    "duration": -1,
                    "target_id": "E01",
                    "type": "walk",
                    "type_id": 0
                },
                {
                    "distance": 0.0,
                    "duration": -1,
                    "target_id": "S01",
                    "type": "walk",
                    "type_id": 0
                },
                {
                    "distance": 0.0,
                    "duration": -1,
                    "target_id": "M08",
                    "type": "walk",
                    "type_id": 0
                }
            ],
            "name_en": "Shinjuku",
            "name_jp": "新宿"
        },
        ...
    },
    "transition_types": {
        "0": "walk",
        "1": "ride",
        "2": "ground"
    }
}

Matrix based format

Other then Stations.json you can also use matrix_dist.csv or matrix_time.csv. These can easily be used with python. Here is a quick example:

import pandas as pd

# Load csv file
matrix_dist = pd.read_csv('matrix_dist.csv', index_col=0)

# Show distance from A05 to A06 in km
print(matrix_dist["A05"]["A06"])
>>> 0.7

Regenerate data files

You'll want to update Stations.json, matrix_dist.csv and matrix_time.csv after doing changes to the data directory. To update Stations.json simply run the following within the repo:

$ generator.py

To update the matrix files, run the following:

$ generator.py -m

For verbose output use

$ generator.py -m -v

Things to do

As of yet there are a few things missing:

• Adding all japanese station names to stations_jap.csv
• Replace duration with distance
• Add distance (listed on wikipedia)
• Add a transition like file for duration
• General code cleanup in generator.py (maybe some progress output?)
• Add real durations to trasitions.csv and lines.csv
• Adding connections to non-metro transport systems (e.g. train stations or airports)
