Which megacity has the most efficient public transportation, accounting for almost 80% of all journeys?

Tokyo is widely recognized for its highly efficient public transportation system, which is a crucial aspect of urban mobility in the city. The efficiency of Tokyo's public transport can be attributed to several key factors.
