The document discusses an app called "Ride On Today" that allows users to check which bus routes are running on a selected date. It imports bus schedule data in GTFS format into a SQLite database to determine which "services" and bus "trips" are active on the chosen date. The stops served by those trips are then plotted on an interactive map to show users the available bus stops and routes for that day. Future work may include automatic schedule updates, support for additional transit agencies, and interactive trip planning features.

2. I like to explore the region by bus
● I’m only available on weekends.
● Some buses are not running on weekends.

3. Official Ride On System Map
● Map includes all
the routes.
● Many are not
running on
weekends.

4. Google Maps
● I want to explore
somewhere new.
● Where can I go?
● Where are you
going?

5. My App
● Select a date.
● A map shows available bus stops on that day.

7. Trip Times are Important, Too

8. How it Works

9. General Transit Feed Specification
● Ride On publishes
bus schedules in
GTFS format.
● It’s a ZIP of TXT files.
– Actually, CSV.
● Can I get the
information out of
these files?

10. What’s in the GTFS?
● List of bus routes.
● List of bus stops, with GPS coords.
● A calendar of “services”.
● List of trips under each “service”.
– trip: a bus serving a route from start to end.
● When does each trip depart each stop.

11. stops.txt in GTFS

12. How the Map was Created
1.Import GTFS files into SQLite database
2.Write SQL queries to find out:
• what “services” are active today
• what trips belong to these services
• where are the stops served by the trip
3.Plot today’s available stops on HERE Maps

13. Future Work
● Automatic GTFS updates
● Multi-agency: MetroBus, Fairfax Connector, and
more
● Interactive maps
● “where can I reach within 75 minutes?”
● “what’s the latest time I must head back?”
