An AC flight was instructed to go around at close to midnight when the ASDE alarm sounded for a runway conflict. They heard the call but didn't think it was for them and landed. The alarm was caused by a driverless vehicle rolling off the ramp and onto the threshold of the runway when the aircraft was on very short final. It had lights on (beacon allegedly sub-standard) but was not seen by the crew. A fortuitous outcome.
