[A BE99] was inbound with low fuel. We were on Runway 1L at the time due to low ceilings and visibility. Since [the BE99] must've been really low on fuel; he declared an emergency and requested Runway 25L. I activated the crash phone and advised the rescue personnel of the situation. [The BE99] was on a 5 mile final for Runway 25L when equipment started responding. (It was a very short time frame/notification from start to finish). As one of the County Operations vehicles was approaching Runway 25L; on Runway 1R; at a high rate of speed; [the BE99] was short final. So guess what happens; the ASDE-X issues a 'GO-AROUND!!!' warning. I could see it was because of the fast target driving north on the intersecting runway and I know we do not have discretion available to us but jee-zo-pete are we supposed to send the guy with no fuel around? I think not! And we did not. So there! Give us some discretion with the ASDE-X tool.
Tower Controller declined to issue a ASDE-X mandated go around to an emergency fuel aircraft on short final; noting the ASDE-X alarm likely occurred because of an emergency vehicle approaching the runway at a very fast speed.
