Cabspotting traces San Francisco’s taxi cabs as they travel throughout the Bay Area. The patterns traced by each cab create a living and always-changing map of city life. This map hints at economic, social, and cultural trends that are otherwise invisible. The Exploratorium has invited artists and researchers to use this information to reveal these “Invisible Dynamics.”
The core of this project is the Cab Tracker. The Tracker averages the last four hours of cab routes into a ghostly image, and then draws the routes of ten in-progress cab rides over it.
The Time Lapse area of the project reveals time-varying patterns such as rush hour, traffic jams, holidays and unusual events. New projects are produced by the Exploratorium’s visiting artists and also created by the larger Cabspotting community.

The brains of London cab drivers

«In a study that generated considerable media interest (and won her an Ig Nobel Prize), in 2000 Dr Eleanor Maguire scanned the brains of 16 London black-cab drivers, who had spent an average of two years learning ’the Knowledge’ – street names and routes in London. The taxi drivers had a larger right hippocampus than control subjects, and the longer they had been on the job, the larger their hippocampus was. These findings seem to indicate that the right hippocampus plays an important role in storing spatial memories.
"When we travel down a route we are familiar with, we often can’t see our destination. Instead, we have an image of it in our mind, and a mental map of how to get there. But this mental map is very different from a street map. I’m trying to understand how we create internal three-dimensional representation of space and our position within it."
She is also interested in another form of memory, linked to spatial memory, which appears to be mediated by the left, rather than the right hippocampus. "Having created an internal representation of large-scale space, how do we structure episodic memories – particular events and personal experiences that occurred at a specific time and place – within that environment?" »
