GreenLine

A hobby project to create an iOS app showing accurate predictions for MBTA Green Line trolleys.

Created by Harrison Wong and Benjamin Chan.

Why? You want to know when your train is coming, but you are at one of the stations that either (a) only shows the next 2 trains when there are 4 possible trains or (b) you are at one of the B, C, or E surface stops without countdown clocks. Additionally, it attempts to be an very lightweight app that has the information you want... but nothing else.

Uses the MBTA v3-API.

TODO

• Table View

  • Remove T logo from front? -- if we ever submit the app, it makes it look like it's endorsed by them
  • Make sure the images are high-res
  • Auto-layout the images properly

• Icon

  • Not sure right now, but maybe a geographically accurate image of green lines

• Predictions Model

  • !!! Trains looping downtown now have time estimates instead of "stops away" estimates, which are currently being filtered out because they don't have a train ID.
  • Figure out if they can be matched to a train car/current location. if not, just put time and tbd for rest
  • Predictions need to be discarded and removed from the table once the train has left the station

• View and Model

  • Auto refresh
  • Pull down to refresh
  • Add table selector to choose station to see predictions for
  • Favorite stations (or nearby??)

• Unit tests

  • Figure out how they work and add them

• Expansion possibilities

  • Make it work for other rapid transit lines and silver line
  • Add handicap accessibility warnings (show stations that have raised platforms/underground stations with elevators/show which car is type 8/9)
  • Add generic green line warnings (meh... text alerts are enough)
