Human Factors
After landing Runway 24R; we were taxiing south on Romeo and crossing Charlie taxiway with a plan to turn left on Bravo.  As we neared the access road between Charlie and Bravo; First Officer and I noticed a vehicle traveling eastbound on the access road at a high rate of speed (40+ MPH).  Fearing the vehicle wouldn't stop short of Romeo; First Officer and I abruptly applied brakes to bring the aircraft to an immediate stop.  We called LAX Ground Control and they in-turn notified LAX City Operations.  The offending vehicle was pulled over by LAX operations as it ended up about 1/3 of the way into Romeo taxiway. We verified with the flight attendants that they and the passengers were not injured and continued to the gate where we coordinated with maintenance to have an additional inspections of the tires and brakes due to the nature of our abrupt stop.[I suggest] some method of illuminating aircraft on taxiways and/or vehicles on access roads would be hugely beneficial.
Captain reported a near collision at LAX; with a vehicle crossing Taxiway R at high speed between Taxiways C and B.
