Cabspotting
Invisible Dynamics, a new Exploratorium project, explores the SF BayArea with (high and low tech) infosthetics.

One of the exhibits is Cabspotting, an online system that tracks and records the movements of Yellow Cabs throughout the Bay Area with GPS.

At top, the dynamic yellow lines represent real-time cab movements through the city. Below is a velocity visualization, where red indicates high speed rides and white bunches display traffic jams.
