This software utilizes the MBTA API to grab alerts and stop lists for public transit routes in Greater Boston. Demo.

• Generate an RSS feed containing alerts, neatly formatted.
• Only include certain routes.
• Allow the user to use an API key.
• Export alerts to Markdown.
• Only include alerts active at a certain time.
• Convert stop lists to Markdown format.
• Convert route schedules to CSV and Markdown format.
• Export alerts and stop lists to CSV.

• requests (pip install requests)

Run the following as root:

make install

Run mbta2rss >out.xml. Then you can open the XML file in your favorite RSS feed reader. An API key can be placed in the environment variable $APIKEY. You can request one here.

• -d datatype: choose type of data to grab (alerts or stops, default is alerts)
• -o fmt: Set output format (rss or md, default is rss).
• -r routes: Set route(s) to look for (comma separated)
• -t time: Set time filter to show alerts active at that time (default shows all times, "NOW" for alerts in effect now, must be in ISO 8601 time format).
• -T title: document/feed title
• -D description: document/feed description
• -U url: upstream URL for RSS feed

• Set up a cron job to update alerts feed every hour or so.
• Email alerts to you (for the route(s) you take or all routes).
• Post alerts on a webpage.
• View alerts in a RSS feed reader.

Add the following to your crontab:

0 * * * * APIKEY="$MYAPIKEY" /usr/bin/mbta2rss >$HOSTDIR/rss.xml

An example of emailing a Markdown-formatted digest using the headmail filter script and sendmail:

APIKEY="$MYAPIKEY" mbta2rss -o md -r "Red,Green-E,66" -t "NOW" | headmail "$FROM" "$TO" | \
	sendmail -a "$ACCOUNT" -t "$TO"

If you wanted to convert it to HTML first, a Markdown to HTML filter must be used (like smu:

APIKEY="$MYAPIKEY" mbta2rss -o md -r "Red,Green-E,66" -t "NOW" | smu | headmail "$FROM" "$TO" | \
	sendmail -a "$MSMTPACCOUNT" -t "$TO"

It is possible to make a HTML webpage (no CSS included by default) for the web using the Markdown output format and piping it into a Markdown to HTML filter. A live demo of this is available here.

APIKEY="$MYAPIKEY" mbta2rss -o md | smu >out.html

1. Without an API key, you are limited to 20 calls per minute.
2. If you publish anything containing content related to this, make sure it is clear this is unofficial and not officially affiliated with the MBTA. They have a license agreement.
3. Green Line routes are differenciated like so: "Green-B", "Green-C", "Green-D", "Green-E"
