Narrative:
SID states 'at 4.5 DME, turn right to 360 degrees.' aircraft X turned to 360 degrees off departure end of runway 31R. Aircraft Y had previously departed on a 340 degree heading. The aircraft conflicted approximately 3 mi north of airport. The way the SID is written causes confusion. Purpose of build-in turn is to avoid dfw departures. Some other procedure needs to be enacted to prevent these numerous errors!
