Workday BART Station Exits - A peak capacity problem.

To get a better understanding of the issues BART (Bay Area Rapid Transit) faces, I wrote a script to visualize BARTS ridership data for the average weekday in 2015. The result is a visual that shows when and where people travel on BART
  
​The regions I used are also shown below. I had to group stations into regions to avoid the graphs looking like magic Eyes.

Disclaimer: Its unclear that if the time BART states for each ride entry is when the rider started or ended the ride. All these graphs assume the ride time is the station exit time.  All times would be shifted forward the length of their ride, if this time is the entry time.

Stations fit into 1 of 4 profiles.

---

Morning Arrival - The stations where people arrive after their morning commute on BART. These are mostly in San Francisco where people from all over 

Embarcadero Station

---

Evening Arrival - The stations where people arrive after their evening commute on BART. These are the majority of stations and most of the commuters are coming from San Francisco

Rockridge Station

---

Dual Arrivals - These stations have similar morning and evening station exits indicating people living here and working here.

Lake Merritt Station

---

Airports - People come to the airport evenly through the day.

All BART station graphs.

Here's the data source on BART's site: http://64.111.127.166/origin-destination/ 
Here's the ipython notebook used to create the graphs.
