Narrative:

Upon taxi out of gate at bwi, we were given instructions to taxi to runway 28. Coming out of alley between pier C and western terminal pier and west of island north of taxiway a. Rather than make the turn on to taxi 'P,' we continued on 'east.' just as the nose crossed the line, I realized the mistake and stopped the aircraft. Ground control also notified us to stop, and asked if we could still make the left turn. We were able, and complied. There was an aircraft in position and holding at the end of runway 28. Contributing factors: 1) the trip was a 'stand-up' overnight with less than 6 hours at the hotel. 2) I had done this exact trip for the last 7 weeks, this is the first time we came out of the alley west of the island between taxiway a and the ramp. We had always pushed back to depart the ramp between the 2 islands. 3) txwys are not clearly marked, and airport layout is confusing. 2 runways ( runway 10-28 and runway 4-22), and multiple txwys (a, P, P1, east, U, D) all intersect in that area. Additionally, txwys change identity (P to P1 to U), and wrap around the terminal (a, P). I did not see any taxi signs marking the runway or direction of txwys. They may have been covered with snow. Baltimore got 2+ ft of snow earlier in the week. This area is a runway incursion hot spot.
