Narrative:

While taxiing into the gate with the aircraft in motion; an air carrier vehicle (a tug used to pull bag carts) driven by a man in an air carrier uniform drove entirely into the designated clear area and then under the right wing area. To avoid a potential collision and in compliance with flight manual procedures I stopped the aircraft until the vehicle was clear. At no time did the guideman direct me to stop. Additionally; I stopped short of the final parking position until the tractor and towbar was moved beyond the equipment clrlines. While waiting for the tractor to be moved the guideman gestured and left the area; evidently ignorant of or unwilling to comply with established parking procedures. The parking process took at least 10 mins.
