When a city opens a subway, which will have a bigger impact on cabs and buses?

First of all, we can't talk about impact, but those two modes of transportation will be affected. Then, the impact of the bus will be greater, the subway can actually be said to be the underground bus, I think part of the role of its emergence is to reduce the ground bus, of course, other roles will not be detailed. Buses and subways have a lot in common, with stops, routes, etc. They are duplicated. It's repetitive. And rental is a kind of irregular, irregular station transportation, and the subway conflict is small. Of course, there are a lot of factors. Personal preference, economic conditions, local area. All in all, the advent of the subway is a good thing. Other means of transportation, the impact is, due to social development, from a certain point of view is inevitable.
