```console
$ ./create_db.sh

Fetched 5007 bus stops.
[END] Fetch bus stops
[START] Collect bus stops
[END] Collect bus stops

[END] Write bus stops
[START] Fetch bus routes
Fetched 26094 bus routes.
[END] Fetch bus routes
[START] Collect bus routes
[END] Collect bus routes
[START] Write bus routes
[END] Write bus routes
Created sqlite database datamall.sqlite
