The MARTA Hackathon series is a yearlong strategic technology initiative led by MARTA, Sandbox ATL, Code for Atlanta, HackGT, and other community groups to help create the next great thing in ATL transit. This presentation showcases the open ridership data being made available to the developer community at the hackathon.

3. Automated Fare Collection - AFC

4. ✓ An Automated Fare Collection (AFC) system is the
collection of components that automate the ticketing
system of a public transportation network.
✓ Data for stations and buses’ daily usage by riders.
Information includes types of devices and cards used,
entries and exits, transfers, fare and passes.

11. GTFS “General Transit Feed Specification”

12. A GTFS feed is composed of a series of text files collected in a ZIP file.
Each file models a particular aspect of transit information: stops, routes,
trips, and other schedule data.
Bus Real Time Information
This contains real-time information about the buses, like Latitude,
Longitude, Delay, BlockID and TimePoint.
Rail Real Time Information
This contains real-time information about the Trains, like
WAITING_SECONDS, WAITING_TIME, DESTINATION, DIRECTION, LINE and
STATION.

13. Variable Definition
✓ Route Short Name Short Description of the Route
✓ Route Long Name Long Description of the Route
✓ Route Type Route is either Bus or Train
✓ Shape Point Lat Route Shape Latitude
✓ Shape Point Long Route Shape Longitude
✓ Shape Point Sequence Sequence of the shape point
✓ Stop Code Code of the stop
✓ Stop Name Name of the stop
✓ Stop Lat Latitude of the stop
✓ Stop Long Longitude of the stop
Data Provided

14. Variable Definition
✓ Arrival Time Arrival at the stop
✓ Departure Time Departure time at the stop
✓ Stop ID Unique identifier of the stop
✓ Service ID Unique representation of service ID
3- Saturday, 4-Sunday, 5-weekday
✓ Block ID Unique representation of Block
Data Provided

15. Bus Real Time Information
This contains real-time information about the buses, like Latitude, Longitude, Delay, BlockID
and TimePoint.
There are two methods you can use to access the MARTA Bus Realtime RESTful data:
GetAllBus — returns all active buses with real-time data across the entire system. http://
developer.itsmarta.com/BRDRestService/RestBusRealTimeService/GetAllBus
GetBusByRoute — returns those active buses with real-time data for a given route. http://
developer.itsmarta.com/BRDRestService/RestBusRealTimeService/GetBusByRoute/{ROUTE}
Ex: http://developer.itsmarta.com/BRDRestService/RestBusRealTimeService/GetBusByRoute/1

16. Rail Real Time Information
This contains real-time information about the Trains, like WAITING_SECONDS, WAITING_TIME,
DESTINATION, DIRECTION, LINE and STATION .
GetRealtimeArrivals — returns real-time train arrivals for all MARTA train stations: http://
