Narrative:

I was working cc/controller in charge so that the supervisor could build currency time on local south. While working the position the asde-X alerted to runway 17 occupied. I looked over to see a CRJ2 about 1/3 of the way down the runway on departure roll; and a CRJ9 parked on L3 around 2/3s of the way down the runway. I could not assess if the CRJ9 was across the hold bars due to the distance from the tower. By the time that I realized where the conflict was and then that the local controller was not cancelling the takeoff clearance (the CRJ2 was now more than halfway down the runway); I felt the situation was not safe to tell the local control to cancel the takeoff clearance. The CRJ2 rotated and appeared to overfly the taxiway L3 intersection by 100 feet AGL.by the time the asde alerted to the situation; it seemed that it was far too late to make a timely correction to the situation. The warning itself seems too long; and the aircraft speed at which it triggers on a departure roll seems high. A ding or other warning sound instead of the word 'warning'; or a slower speed on departure roll triggering the 'occupied' warning could increase the time available to fix a situation like this.
