最近看到一条不错的讨论:

In most cases, during daytime and downwind if the highway, the air
is back at urban background levels at around 400 m from the centerline
of the road. Things get bit more complicated during nighttime, but I'd
say that's the big picture. And as always with things like this, the
decay is exponential, so e.g. 150 m away from the road you have like
three times lower concentrations than at 100 m from the road. I'd be
happy to buy a home that was more than 300 m away from the nearest
highway.

这位发帖人士,应该是某个研究所或者高校的。
结论: 住家离高速建议有400m的距离
(显然,之前讨论过的Normanton P 就不符合这条)。

高速边上的房子,主要是车辆噪音,非常难处理。
如果直接面对高速,400感觉够了,我印象中是每100米衰减10db。如果有一栋或者半栋挡着,噪音马上低很多。缺点就是视野不开阔。
高速边上,要么做类似办公大楼的隔音和新风系统,要么有楼挡着。
空气如果高楼,没问题的。
