Public transit as a cheap, environmentally friendly and popular transportation, which plays an extremely important role in urban travel. It is a topic of great concern for public transit agencies and urban traffic policymakers to better understand citizens’ attitudes to ride-hailing services and urban public transit use as well as the relationship between the two modes of travel.
