Narrative:

On landing runway 10, bwi, at night, damp runway, decelerating for turnoff at taxiway east, were issued instructions to turn off on taxiway east, taxi onto taxiway P and contact ground. In the midst of changing control of aircraft (first officer made landing) we responded 'roger' and complied. Exiting, I saw an aircraft on my right, on what I assumed was taxiway P. I also assumed the aircraft was stopped for us, the exiting aircraft as first officer was contacting ground. I entered the ramp directly ahead and adjacent to our intended gate. On doing so I realized the aircraft I saw was on a close parallel taxiway a. Ground asked us to call tower on the phone. We discussed the situation, I apologized for the confusion, assured them I saw the other aircraft and in the brief moment at high workload proceeded to the ramp area. In an area on the airport with high potential for conflict, and at a time of very high workload for landing aircraft, and night conditions, it would be better for the low workload aircraft (taxiing) to make adjustments (ie, hold position momentarily) than for the runway clearing aircraft to do so.

Title: AN ACR B737 FLC TURNED OFF THE RWY AT THE CORRECT TXWY THEN CUT IN FRONT OF ANOTHER ACFT THAT THE CAPT 'ASSUMED' WAS HOLDING FOR THEM.

Narrative: ON LNDG RWY 10, BWI, AT NIGHT, DAMP RWY, DECELERATING FOR TURNOFF AT TXWY E, WERE ISSUED INSTRUCTIONS TO TURN OFF ON TXWY E, TAXI ONTO TXWY P AND CONTACT GND. IN THE MIDST OF CHANGING CTL OF ACFT (FO MADE LNDG) WE RESPONDED 'ROGER' AND COMPLIED. EXITING, I SAW AN ACFT ON MY R, ON WHAT I ASSUMED WAS TXWY P. I ALSO ASSUMED THE ACFT WAS STOPPED FOR US, THE EXITING ACFT AS FO WAS CONTACTING GND. I ENTERED THE RAMP DIRECTLY AHEAD AND ADJACENT TO OUR INTENDED GATE. ON DOING SO I REALIZED THE ACFT I SAW WAS ON A CLOSE PARALLEL TXWY A. GND ASKED US TO CALL TWR ON THE PHONE. WE DISCUSSED THE SIT, I APOLOGIZED FOR THE CONFUSION, ASSURED THEM I SAW THE OTHER ACFT AND IN THE BRIEF MOMENT AT HIGH WORKLOAD PROCEEDED TO THE RAMP AREA. IN AN AREA ON THE ARPT WITH HIGH POTENTIAL FOR CONFLICT, AND AT A TIME OF VERY HIGH WORKLOAD FOR LNDG ACFT, AND NIGHT CONDITIONS, IT WOULD BE BETTER FOR THE LOW WORKLOAD ACFT (TAXIING) TO MAKE ADJUSTMENTS (IE, HOLD POS MOMENTARILY) THAN FOR THE RWY CLRING ACFT TO DO SO.
