Narrative:

After pushback from gate; we had to wait for the aircraft next to us to park before starting our taxi. His parking was delayed (properly) by the marshaller as numerous ground service vehicles drove in front of the aircraft.once they finally cleared; I turned my taxi light on and started to turn; only to have to slam on the brakes and stop as a baggage cart and a catering truck both drove in front off my aircraft. Had I not stopped; my wing would have made contact with the catering truck; and the baggage cart would have been well under my wing.this problem in seriously increasing in denver. Ground vehicles on the service road in front of the gates are not yielding to aircraft; especially on taxi-out.
