A team of graphics artists has attempted to map the private buses that carry workers from San Francisco to Silicon Valley, reports the Wall Street Journal. At least six employers–Apple, ebay, Electronic Arts, Facebook, Google, and Yahoo–offer such services, but they are very secretive about where they go and how many people they carry.

The artists who developed the map estimate that these private buses carry about a third as many people as CalTrains commuter trains between San Francisco and San Jose. CalTrains cost taxpayers more than $110 million a year, but Silicon Valley firms obviously don’t believe they adequately serve their employees, probably because the rails don’t go near their campuses. Google alone has more than 100 buses in its fleet, about as many as serve the entire fixed-route system in the city of Stockton.
