I know one thing. If I was ever in charge of operating a private road and let’s say the traffic was jammed up due increased numbers of people using it. I could do 2 things:
1) Add more lanes to accommodate the increased demand.
2) Double the tolls without adding lanes.
Both would end the traffic jams.
Easy choice for me, and my company’s stock price!
You clearly don’t live in the DC metropolitan area.
You’d eventually have to add lanes. People would eventually get sick of your sh*t and go back to podunk roads if you just kept increasing tolls.
Look up “shunpiking” in relation to the Pennsylvania Turnpike . . . and that’s for a road that’s actually adding lanes as well as increasing tolls.
