Color code the stations, please!
BART is notoriously difficult to navigate for those who are from outside the Bay Area, and there is clearly a lot of room for improvement in terms of signage within the BART stations. Friends of mine from out of town are constantly getting lost on BART and having to ask for directions, when simple improvements to station signage could eliminate these problems.
Here are a couple suggestions:
1.) Color code the stations to match the various train lines. If I'm in Walnut Creek, the station should have a big yellow stripe running along the wall. If I'm in Berkeley they should be Orange & Yellow, etc.
2.) Arrows & station names printed on the walls indicating which direction the trains will be going in and what the end locations for each direction are. "Inbound/Outbound" doesn't cut it for visitors who aren't familiar with the system or the Bay Area. The termination points for each line need to be listed on the wall along with the colored stripe designating which line it is, and arrows pointing in the directions the trains are going.
What other suggestions do you guys have for improving signage along BART?
