As part of the resolution, the USSF has developed an extensive program to improve concussion awareness and education amongst youth coaches, referees, parents and players, a statement said.
Rules governing the maximum number of substitutions would also be tweaked to ensure they did not act as an impediment to the evaluation of players who have suffered a concussion during matches.
"In constructing the concussion component, US Soccer sought input from its medical science committee which includes experts in the field of concussion diagnosis and management, as well as from its technical advisors, and worked with its youth members to develop a true consensus-based program," US Soccer chief executive Dan Flynn said in a statement.
Steve Berman, lead counsel for the plaintiffs, said the new safety measures met the objectives of the case, which would now be dropped.
"We are pleased that we were able to play a role in improving the safety of the sport for soccer-playing children in this country," he said.
A recent study by scientists in Denver looked at concussions in US high school soccer between 2005 and 2014.
The study reported that while rules outlawing heading would likely reduce the number of concussions, the main causes of head injuries involved athlete-to-athlete contact.
