Narrative:

Ground vehicles failure to yield. The aircraft was stopped short of the gate awaiting ground equipment removal from the safe gate clear zone. (The ground crew seemed confused as to why equipment; a towbar; that would have disappeared under the aircraft's nose inside the clear zone needed to be moved.) once the tow bar was removed; I began advancing power to complete parking but had to stop because a steady stream of our carrier's vehicle traffic began entering the clear zone from each wing tip area and drove directly in front of the aircraft preventing any movement. After a couple of minutes; it became apparent the traffic would not stop and the ground crew had no intention of stopping the vehicles; the engines were shut down and the aircraft was towed the rest of the way to the gate. A briefing was given to the ground men on the headset to stop encroaching traffic. These ramp problems in mia continue on a regular and frequent basis. Since the problem is widespread and continuous in mia I would suggest the responsible supervisor/manager be replaced and the new supervisor; by whatever means available; correct that safety problems on the mia ramp. They might consider having the airport authority revoke/suspend the sida badges of the offenders for failure to yield to aircraft. Personally I would begin hiring and training new employees to be ready to take the place of those unwilling to perform their job in a safe manner. Give notice to all current employees with ramp access in the form of a brief; but specific written safety guidelines directive that they must sign affirming their understanding and willingness to comply. The notice should include the consequences of violating these fundamental safety guidelines. (That's why you need to have new employees available for those that are too arrogant to comply with simple safety rules that not only prevent aircraft damage; but could actually save their life.)

Title: A B757 Captain reported that his company's MIA ramp personnel failed to clear equipment from the gate area in a timely manner and then as taxi was resumed to the gate; ground traffic prevented the aircraft's gate arrival. The engines were shutdown and the aircraft towed to the gate.
