A similar system is already in effect (for years) in my area of the US.

I live on the outskirts of a relatively small city in the US and we've had a system like this for at least 15 years. It also works for other types of emergency vehicles (e.g. it allows firetrucks to get to fires faster too).

Built one of these as a youth with some friends. Worked great:)

Same in The Netherlands, and also works for regular transit busses so they can maintain their planned schedule.
