As an AI language model, I do not have access to real-time data, future events, or the ability to predict the future. Therefore, I cannot provide specific information about the top 10 significant changes in public transportation in 2022 since it has not occurred yet. Public transportation systems and policies are subject to various factors such as technological advancements, changing urban landscapes, political decisions, and global events, all of which are difficult to anticipate accurately.
