3-5 rides/week Yes No 2 1-2 Rides 3 I think station safety and crime information (especially late night L
10+ rides/week Yes Yes 3 3-5 Rides 2 rides) should be a higher priority. Luckily there's the "guardian
Curve Ball
angels" organization which has helped me feel safer in the past.
3-5 rides/week No Yes 3 10+ Rides 8
But much more can be done. It would be nice to have a safe and
10+ rides/week Yes No 4 clean subway system like Toronto, Canada or even Washington
10+ rides/week No No 3 D.C. Our current L system could deter Chicago tourists, scarring
1-2 rides/week Yes No 3 their view of our beautiful city. Also, a dashboard update of train
10+ rides/week Yes Yes 3 location and arrival times would be FANTASTIC.
1-2 rides/week Yes No 3

24. Home Screen
Simple tap and go options for users. Riders can choose
a station themselves, have the application find the
nearest one, view their saved stations, or adjust their
settings, all from the home screen.
25. Choose a Line
Simply tap a line to see all the stations on
that line. To change train lines, swipe from
left to right to see the “Choose a line” screen
again.
26. Choose a station
While choosing a station riders can see
exactly where the trains are and which
directions they are heading. Choosing a
station is as simple as tapping the one they
want. Update train locations by pulling and
releasing the top bar.
Rotating the phone 90º quickly changes the
route direction eliminating the need to scroll
through the entire list of stations.
27. Choose a station
Swiping from right to left on a station brings
up a contextual menu for riders. From the
menu they can find friends on the train at
that station, look for other transit options
nearby (e.g. buses arriving or departing
soon), save that station, or set an alarm when
they arrive at that station.
28. Share with Friends
From the station contextual menu, selecting
the first item allows riders to share their
location on the train with friends, and also
see where their friends are at on the train.
Riders can choose the car they are entering
or on, and then on the next screen choose
where in the car they are at. At the top
riders can see which friend is in the train car,
and where they are at.
29. Station Information
Once riders choose a station, they can see
the station name, when the train will arrive
at that location, and recent crime
information. Again, rotating the phone 90
degrees will change the direction for riders,
or they can simply tap the icon next to the
station information.
Riders by default will see crime data for that
station for the last week. Swiping from left to
right on the Crimes bar, changes the data
view allowing riders to see a crime summary
over the last month. Other data such as how
often trains are delayed or on time at the
station could also be visualized.
