P50 traffic jam is a period-50 oscillator discovered by Noam Elkies on October 16, 1994.[1] It works by hassling the 25-generation traffic jam reaction with two copies of fumarole and two copies of octagon 2. In terms of its 92 cells, it was the smallest known period 50 oscillator until May 18, 2022, when 46P10 on 30P25 was found.[2] The version shown is the cis version, and by reflecting the right side it is possible to get a trans version with also 92 cells.

The traffic jam reaction gives off strong dot and obo! sparks. Nothing has been found that requires the p50 traffic jam, but oscillators have been found using the same reaction at other periods, as described in p44 traffic light hassler. The period-50 glider gun used the p50 traffic jam in a different way before the much smaller 55P10 was discovered.
