What are some benefits of public transportation?


assistant
Public transportation is better for the environment. Buses and trains emit less carbon dioxide per person than private transportation. Public transportation is more affordable than private transportation. By spreading out the cost of transportation ownership and maintenance among the large number of public transportation riders, public transportation is cheaper than private transportation.
