An interactive visualization of data over time from the National Transit Database.
Do you wonder how much it costs to run your transit system? The National Transit Database holds data for transit systems in the U.S. I’ve gathered some key statistics and presented them in an interactive visualization.
In the case of Wichita, we see that “OpExp per PMT” for 2015 is $1.02. This is total operating expense per passenger mile traveled. It’s not the cost to move a bus a mile down the street. It’s the cost to move one passenger one mile. And, it is operating cost only, which means the costs of the buses are not included.
Some definitions used in the database:
- UZA: The name of the urbanized area served primarily by a transit agency.
- UPT: Unlinked passenger trips.
- PMT: Passenger miles traveled.
- Total OpExp: Total operating expense.
The visualization holds three tabs. One is a table of figures. The other two illustrate data for a single transit system or single mode.
