Watch Transit Move With These Animated Maps
Will Geary explains the thinking behind, TransitFlow, "an experimental set of tools to generate spatial-temporal transit frequency datasets and visualizations from the command line."
That is, TransitFlow allows the creation of animated maps showing the movement of public transit modes around cities and regions. The TransitFlow team created the tool to help illustrate the importance of frequency, among other critical aspects of transit service.
See below for examples of the San Francisco Bay Area, New York City, Amtrak trips around the United States, and Mexico City.
There are a lot more examples from around the United States and the world available on Geary's Vimeo portfolio.
