LaGuardia has that system, it still failed to prevent this

Transponder doesn't alter the laws of physics for the landing plane you just cut off. I guess it gives ATC a ~5sec jump on telling some other flight to go around.

I'd bet a lot of money that however the system is implemented the police and fire get special treatment when it comes to process (i.e. asking permission before they go somewhere planes might be) and that is part of what lead to this.

I highly doubt that any system would intentionally give ground vehicles of any kind special treatment on an active runway.

		The trajectory of the plane is obvious enough that it should be able to predict where it will likely be in 30 seconds or a minute. You can't cheat physics, if it is going down in direction of runway, it is landing or at worst will do go-around, so the services should be alterted runway is no-go automatically
