Airport; Procedure
After pushback; while centered on Taxiway D8 in the alley between terminals [1 and 2]; I noticed multitudes of vehicle traffic (Passenger buses; tugs; fuel trucks; etc.) moving along the edge of the alley. Unfortunately; those Ground vehicles have no defined lane to stay within that guarantees wingtip clearance from taxiing aircraft. As a result; the Ground traffic did not move in a standardized flow/distance from our aircraft in the alley. In fact; depending on size/type of aircraft parked at their gates; the ground traffic was not able to move in a straight line and would move out toward the center of the alley. In my assessment; the risk for misjudging vehicle/aircraft wing tip clearance; by either Aircrew or Ground Personnel; will increase during low ambient light and/or low visibility conditions.Airport Operations should paint a Ground vehicle taxi lane that guarantees clearance from aircraft pushing and entering/exiting the length of the alley between Terminal 1 and 2. Operations should emphasize the higher risk/potential for collision in this area during annual Ground Operator refresher training and initial qualification. At a minimum; update Company bulletin to warn Crews about uncontrolled vehicle movement in close proximity to taxiing/pushing aircraft and the need for increased vigilance.
Air carrier Captain reported that ground vehicles at LAX Airport have no defined travel lane to remain clear of taxiing aircraft in areas between Terminal 1 and 2.
