They work for highway, bridges etc. I think OP was suggesting something like every road in a city being a toll road, with a different toll per road. How much infrastructure would be needed to make this drivable, get the different road owners their money, make sure that each road owner is maintaining it.
Better to have these huge number of interconnected roads maintained by one group responsible for them.
