[Fidelia]

Commercial transporters are faced with a choice to make on which route to ply amongst the different routes available.

What determines the route that a commercial transporter would ply per time?

In Nigeria I think the drivers gets their schedule at the bus station. You don't just ply routes on your own

For a driver that just does city driving, they decide the routes to ply based on activities that are happening at a particular route per time.
