Your Commute

This section lets you choose two stops along the same line then renders a scatter plot with range bands that show what the wait and transit time between those stops is across all weekdays during the month. your-commute.js renders the map glyph, scatter plot scaffolding, and sets up interaction with surrounding text. Each time a user begins dragging from one stop to the next it reads in a data file containing transit and wait times for the month from that starting station and renders the data when the user finishes dragging.

Required data format

This visualization requires 3 data files to render the initial map glyph

• station-network.json nodes (stations) and links that represent the network topology of the subway system
• spider.json screen placement for stations in order to render the map glyph
• station-paths.json list of valid stations that you can drag between (a list of station IDs per line)

Then when a user begins dragging, an additional file is read in that contains wait and transit times from the starting station to all other stations

• upick2-weekday-rollup-<starting station GTFS ID>.json wait and transit times to all stations from the station with the given ID

station-network.json and spider.json are described in [Common Data Files](Common Data Files).

station-paths.json

Contains a list of station IDs per line used to determine what stations you can drag to from a starting station.

[
  [
    "GTFS ID of station along line 1", ...
  ],
  [
    "GTFS ID of station along line 2", ...
  ], ...
]

upick2-weekday-rollup-.json

Contains the historical wait and transit times from this starting stations to all other ending stations.
