MIT BIG DATA CHALLENGE

BIG DATA
2.3 MILLION TAXI RIDES in 4 VIEWS
TEAM: Kael Greco and Veronica Hannan
DATE: 20 January 2014

Visit the prototype site here (to see the data compressed into one representative week), or here (to see two distinct days of activity).

VIEW 1 - ACTIVITY SNAPSHOTS
Boston area transportation activity for a representative week from May to November. Each time slice aggregates total taxi activity in a two hour interval for each day of the week. Teal denotes a taxi pick up event while pink designates a taxi drop off event. Points of interest are shown in white. Each subway and BRT line expands and contracts with their total ridership per two hour time block for each day of the week in June.

VIEW 2 - TAXI SUPPLY AND DEMAND
Boston area transportation activity for a representative week from May to November. Discrete taxi pickup and dropoff events are replaced with a difference map. Spikes in unmet taxi demand are highlighted as pink valleys, and excesses in taxi stock are shown as teal hills. Purple denotes a balance in supply and demand.

VIEW 4 - NEIGHBORHOOD CONNECTIONS
Boston area transportation activity for a representative week from May to November. Here all incoming and outgoing trips are summed by neighborhood and visualized as a network. Taller, thicker lines represent stronger connections across neighborhoods (more trips between them). Origins (taxi pickups) are shown in teal and destinations (taxi dropoffs) are shown in pink.
