Narrative:

I was training someone on ground control. He requested a poor crossing because there was an aircraft a little too close he didn't see. The local controller denied the crossing. Then the ground controller then read the hold short instructions correctly to the pilot of aircraft X. The pilot read back the hold short instructions incorrectly although the language barrier and/or order he used made it difficult to understand his incorrect read back. The aircraft then crossed runway xxl at alpha with aircraft Y on about 3/4 mile final. I saw the aircraft X entering the runway and immediately told local control to send around aircraft Y on final. I was going to have aircraft X stop; but he was already too far forward so I had him continue across runway xxl and hold short of runway xxr. Aircraft Y landed without a go-around because aircraft X had crossed the runway. I have said this before; but I think this facility needs to have a safety logic system. There are a multitude of disparate reasons that there are so many runway incursions here; but because of this very reason; no single procedural change will fix it all. A safety logic system adds a needed layer of safety and should be considered as soon as possible.

Title: Ground Controller reported an runway incursion because of a bad read back.

Narrative: I was training someone on Ground Control. He requested a poor crossing because there was an aircraft a little too close he didn't see. The Local Controller denied the crossing. Then the Ground Controller then read the hold short instructions correctly to the pilot of Aircraft X. The pilot read back the hold short instructions incorrectly although the language barrier and/or order he used made it difficult to understand his incorrect read back. The aircraft then crossed Runway XXL at Alpha with Aircraft Y on about 3/4 mile final. I saw the Aircraft X entering the runway and immediately told Local Control to send around Aircraft Y on final. I was going to have Aircraft X stop; but he was already too far forward so I had him continue across RWY XXL and hold short of RWY XXR. Aircraft Y landed without a go-around because Aircraft X had crossed the runway. I have said this before; but I think this facility needs to have a safety logic system. There are a multitude of disparate reasons that there are so many runway incursions here; but because of this very reason; no single procedural change will fix it all.
