Narrative:

On landing rollout runway 22R decelerating through about 100 KTS, tower gave turnoff instructions and ground frequency. Our landing clearance had included 'hold short of runway 27R.' I took control of aircraft from the first officer who had landed and turned off to the left on taxiway C as we always had previously. After reaching our gate, I received a message to call the tower. They informed me we had been instructed to turn right off runway 22R onto taxiway Z. This was apparently a new taxiway and new procedure to help alleviate ground congestion. I had noted an unusual frequency given on our rollout for ground control, but was not familiar with taxiway Z. I did in fact turn left off runway 22R instead of right as instructed. There was confusion and my thought was to depart the active runway in the manner we always had previously rather than stop on the runway to clarify the unfamiliar instructions. In spite of the fact that I was wrong, I feel the situation would not have occurred if there had been any kind of information on the ATIS or from the tower when our landing clearance was given as to what to expect on rollout. It was a totally new procedure ord was trying out and a little advance notice would have been most helpful. Last 'second' instructions during a landing rollout are not always acceptable or appropriate.

Title: AN ACR FLC RECEIVES AN INSTRUCTION FROM THE TWR DURING THE LNDG ROLLOUT. THEY THEN TURN THE WRONG DIRECTION AND USE THE WRONG TXWY TO THE GATE.

Narrative: ON LNDG ROLLOUT RWY 22R DECELERATING THROUGH ABOUT 100 KTS, TWR GAVE TURNOFF INSTRUCTIONS AND GND FREQ. OUR LNDG CLRNC HAD INCLUDED 'HOLD SHORT OF RWY 27R.' I TOOK CTL OF ACFT FROM THE FO WHO HAD LANDED AND TURNED OFF TO THE L ON TXWY C AS WE ALWAYS HAD PREVIOUSLY. AFTER REACHING OUR GATE, I RECEIVED A MESSAGE TO CALL THE TWR. THEY INFORMED ME WE HAD BEEN INSTRUCTED TO TURN R OFF RWY 22R ONTO TXWY Z. THIS WAS APPARENTLY A NEW TXWY AND NEW PROC TO HELP ALLEVIATE GND CONGESTION. I HAD NOTED AN UNUSUAL FREQ GIVEN ON OUR ROLLOUT FOR GND CTL, BUT WAS NOT FAMILIAR WITH TXWY Z. I DID IN FACT TURN L OFF RWY 22R INSTEAD OF R AS INSTRUCTED. THERE WAS CONFUSION AND MY THOUGHT WAS TO DEPART THE ACTIVE RWY IN THE MANNER WE ALWAYS HAD PREVIOUSLY RATHER THAN STOP ON THE RWY TO CLARIFY THE UNFAMILIAR INSTRUCTIONS. IN SPITE OF THE FACT THAT I WAS WRONG, I FEEL THE SIT WOULD NOT HAVE OCCURRED IF THERE HAD BEEN ANY KIND OF INFO ON THE ATIS OR FROM THE TWR WHEN OUR LNDG CLRNC WAS GIVEN AS TO WHAT TO EXPECT ON ROLLOUT. IT WAS A TOTALLY NEW PROC ORD WAS TRYING OUT AND A LITTLE ADVANCE NOTICE WOULD HAVE BEEN MOST HELPFUL. LAST 'SECOND' INSTRUCTIONS DURING A LNDG ROLLOUT ARE NOT ALWAYS ACCEPTABLE OR APPROPRIATE.
