In Training; I had an SR20 holding short of Runway 19L ready for departure. A second SR22 contacted Local Control 1 and requested to cross Runway 19L. I approve the crossing and also cleared the SR20 for take off on Runway 19L. I assumed my SR20 was in front and the crossing SR22 would cross behind my departure. I should have specified to the Local Control 1 Controller to cross behind my departure instead of just cross. I should've specified to the Local Control 1 Controller to cross his aircraft behind my aircraft.
I was a solo pilot in my SR20. I was holding short on the east side of Runway 19L on Taxiway Kilo. I was using the right half of the taxi hold short area. I had contacted the Tower and had been in contact with them while holding for a landing helicopter on Runway 19L. To my left; and slightly behind me; was SR22 holding on the left half of the taxi hold short area. Its nose was at about the 8 o'clock position. I did not hear the other Cirrus speak to the Tower on my frequency. It likely was on the Ground frequency or on the other Tower frequency. After the landing helicopter took off; I was cleared for takeoff on 19L and acknowledged 'Cirrus cleared for takeoff Runway 19L at Kilo.' I moved my throttle to half power as I was executing the 90 degree left hand turn to enter the runway. It was my plan to make a 'running start' by continuously rolling from the taxi area until centered on the runway so that I could then use full power. As I was executing my takeoff roll; I saw movement out of my left eye. I then looked to my left; and saw the SR22 crossing Runway 19L in front of me. The SR22 was going straight forward; to continue on Taxiway Kilo toward Runway 19R. I never heard any communication between the Tower and the SR22; nor did I receive any communication from the Tower before executing an emergency stop. When I saw the SR22 cross my path; I immediately braked in an emergency stop and cut my power. I called the Tower after doing so; and told them I was going to stop and wait until further advised; and I may have said I was blocking the runway. A different Controller (name unknown; but whose voice I recognize as an experienced controller) came on the frequency and told me to hold. The SR22 continued to taxi north off the runway and onto Taxiway Kilo between Runways 19L and 19R; and I was then cleared for takeoff. I never heard any communication between the Tower and the other SR22 was given a number to call after taking off; and called the Tower after completing the flight. I was told that ATC was training on Runway 19L; and that the trainee had made an error. I also was told that ATC would be reviewing the matter. I left all my pertinent contact information with ATC. The ATC Supervisor I spoke to was very professional in the matter and advised me I had done nothing wrong and this incursion was due to a training error caused by the trainee becoming confused by the fact that there were two Cirrus aircraft lined up in close proximity.
Local Controller in training issued a runway crossing clearance to another Local Controller and then issued a conflicting take off clearance resulting in an aborted take off. Pilot of conflicting takeoff clearance states I called the Tower and told them I was going to stop and wait until further advised.
