In the U.S. we put a sticker on the windshield that gets scanned when the car passes through. While you are supposed to slow down a bit they work just fine at 100km/hour. They could leave the road at 4 lanes and get rid of all of the booths. Minimal traffic back up.
We purchase the stickers at your local grocery store.

They work just fine at 140km/h too. There are parts of Texas where toll roads are 85mph.
