Procedure; Human Factors
While performing touch and go's in the pattern; [I] was directed by ATC to maintain 1;100 feet pattern altitude. On one departure off Runway XX I was directed by ATC to extend my upwind 1 mile before starting crosswind turn. I complied with this ATC instruction. After I started my right turn for the right downwind leg; a Cessna departing Runway XX behind me turned crosswind and had a vector that appeared to be a collision course with me. My ADSB alerted to me to this traffic conflict as well as my Safety Pilot who is also a certified pilot. A few seconds later; the ADSB traffic conflict did not go away; and I had a visual of the conflicting traffic. I heard ATC ask the Cessna if they had me in sight; and the Cessna did not immediately respond. The Cessna continued to appear larger in size; so to avoid a potential collision; I climbed in altitude to 1;500 feet. I estimated the Cessna came within 500 feet of me. As I climbed to safety; I alerted ATC that I was climbing for a traffic conflict; the Cessna who turned into my flight path and was a threat to me. ATC advised me to just maintain VFR and at that point I heard the Cessna tell ATC they just got positive ID of me. This was after I made my escape maneuver. Continued on downwind at 1;500 feet and when ATC had the Cessna behind me maneuver to leave enough space for me to descend back to 1;100 feet; ATC advised me to descend back to pattern altitude then cleared me for touch and go. No other conflicts after this one. It can't be overstated that ADSB was a life saver today. ADSB is what first tipped me off about the conflicting traffic as well as its potential collision course.
PA-28 pilot reported an NMAC in the traffic pattern when the trailing departure pilot turned an early crosswind.
