I'm sorry, but I don't understand your comment.

Yes, every road is different. So pay careful attention to the design of every road, rather than following a standard (eg, 12') plan, so people naturally want to drive at the safe speed limit. Design the roads for the speed limit. Don't overdesign the roads, then use signs to force everyone to slow down from what they naturally want to do.

That's still standardization, but based around people rather than a Platonic street design. And it brings its own advantages.

Regarding traffic calming, and quoting from https://en.wikipedia.org/wiki/Traffic_calming :

> Traffic calming consists of physical design and other measures, including narrowed roads and speed humps, put in place on roads for the intention of slowing down or reducing motor-vehicle traffic as well as to improve safety for pedestrians and cyclists.

So yes, it's partially about reducing traffic, but it's definitely also about slowing people down.
