Human Factors
Left downwind for Runway 28 abeam end of runway at 1500 feet. Had been advising CTAF of position multiple times. ADSB traffic alert of traffic 1 mile same altitude. Only other traffic on CTAF was on base and final legs for 28. A second automated traffic alert sounded and I spotted the traffic at 12 o'clock closing fast at which time I aggressively banked left while initiating a descent and had a high wing single engine pass off the right side traveling opposite direction. Joined base leg and landed without further incident.
