What was a nonviolent protest used to fight segregation on public transport system?

One notable nonviolent protest against segregation on public transport was the Montgomery Bus Boycott, which began in December 1955. Sparked by Rosa Parks' arrest for refusing to give up her seat to a white passenger, the boycott involved African Americans refusing to use the city buses in Montgomery, Alabama. The protest lasted for over a year and aimed to challenge the discriminatory policies of segregation on public transport, ultimately leading to a Supreme Court ruling that declared segregation on buses unconstitutional.
