American Smart Motorways

Post by jervi »

Was in Las Vegas earlier this year and did see some construction works taking place - turns out its their equivalent to a smart motorway (active traffic management)

Not too sure what I think of it tbh, in general their signs are shocking, and having to put them on gantries is just a pain.
Another issue for them is that things tend to not be Nationwide, and every other state will likely use their own standards.

There have been variable speed limits in the USA for some years. I-495 around Washington has them as have I-95 and I-16 around Savannah.

Overhead speed limits have been present on the New Jersey turnpike for a long time.

Given the huge differences in the level of use and road conditions in the USA between states there are bound to be variations in these matters even if there was no legal differentiation. Driving from NYC towards Bangor Maine is an education.

Interstate 5 in Seattle has a good example of variable mandatory speed limits and tidal flow express/local lanes along with hard shoulder running.

It all looks very well presented. The fact I-5 through Seattle is completely bonkers as an urban freeway given it's double and triple-decked just makes it better.
