A single map covering the entire Bay Area rail transit network, in simplified diagrammatic (rather than geographically accurate) form. Like all diagrammatic maps, it was inspired by the iconic London Underground tube map; it was also inspired by a visit to Singapore, where an unfamiliar transit system was rendered navigable by a remarkably easy-to-digest map. The current BART map is reasonably clear, and large printed versions encompass the whole region and include other rail providers. However, the map emphasizes BART at the expense of other agencies, and is something of an awkward hybrid, neither really geographically accurate nor as simple as could be. (Note that BART service to SFO and Millbrae has been reconfigured since this map was last updated.)
