Flight Crew Air Transport Pilot (ATP)
Conflict Ground Conflict; Less Severe; Ground Incursion Runway
Flight Crew Executed Go Around / Missed Approach
Human Factors; Procedure
On approach to Runway 8R in IAH on glideslope. When we were [at] 1.3 NM from the threshold (per FMS range to runway reading) ground traffic (aircraft about to cross our runway) was on NE [at] CC taxiway; approaching Runway 8R at high speed. 0.9 NM from the threshold the ground traffic (crossing aircraft) was still on the runway surface area. The Captain (PF) immediately executed a go-around. Subsequently ATC issued a clearance to climb to 2;000 FT and turn to heading 360 for a downwind for Runway 8L.IAH Tower lost situational awareness of the ground traffic and us; as well as our respective distances to the 8R threshold area; thus causing this situation. Tower didn't advise either of us about the other. With the sun in our back the ground traffic would have had difficulty seeing approaching traffic.

EMB-145LR flight crew reported they executed a go-around when another aircraft taxied onto their runway when they were a mile out. Flight crew felt it was an ATC error.
