Multiple aircraft were inbound to the D8 alleyway. The first one did not immediately go on their gate; causing the aircraft in-trail to back up and block Taxiway D. While these aircraft were impeding onto Taxiway D; buses were backing up; facing eastbound at the top of Terminal 2. These buses; I believe; were waiting to go into the D8 alleyway; but held out due to the stopped aircraft. After several minutes of the aircraft blocking the taxi lane; one bus; identified as Bus X on the ASDE-X; drove into the middle of the D taxi lane eastbound across D8 and toward D7 at a high rate of speed. Simultaneously; Aircraft X was taxiing parallel to this bus on E toward D7 and was going to 'double-back' at D7 onto D short of D8 due to traffic. Once I noticed the erratic bus; I keyed up to Aircraft X and suggested they hold position due to a 'rogue bus on the taxi lane that I was not [in] communication with and I was unsure of their intentions.' Aircraft X reported the bus in sight and stopped. City Operations also heard this transmission and reported they were enroute to see what was going on.Bus X then made a 180-degree turn in the middle of D at the D7 intersection and proceeded to drive westbound on D to the area they had just come from. I advised Aircraft X that the bus had appeared to clear the movement area and they could continue their taxi. Operations intercepted Bus X at this time toward the south end of the D8 alleyway; but I have no further information on how this incorrect use of the movement area was handled.This example was just another instance of buses continuing to operate in a manner that's completely contrary to the LAWA's Airport Rules and Regulations. Buses should not be operating on taxiways or in the middle of the D taxi lane at any time. I am once again recommending that the FAA address this critical safety issue with LAWA. The answer that I previously received to [a prior report] that the situation has been remedied is not the reality. While it may be the case that LAWA addressed the discrepancies with the bus drivers; they need to now police and enforce their policies because the rules are absolutely not being followed and users operating on the north complex are in jeopardy as a result.
