Are you talking about ramp metering?
If so, I was involved in a trial in Melbourne, Australia on a major highway there. In peak times, it can actually improve travel times by 50% and massively reduce congestion around the choke points you get just ahead of on-ramps.
It depends on what algorithm they use to determine timing though - this was a coordinated, dynamic algorithm, but sometimes they are just manually set which isn't as good.
- remarkEon 11y agoI am! Do you have any datasets that you can release that I could look at? Or what the algorithms looked like? I'd love to be armed with some real facts the next time I get annoyed or my coworkers start complaining.
