My hometown! Cool to see it on HN. Maastricht uses to be the only traffic lights on route from Amsterdam to Paris. Yes. Traffic lights on a highway, in the middle of a city. As if the highway in the middle of a city wasn't annoyinh enough the traffic lights added some extra noise, fumes and pollution. The new tunnel has been the most magnificent change I've ever seen. And IIRC the entire project was within budget and…

Was an eastern bypass for long-distance traffic studied?

>>Maastricht uses to be the only traffic lights on route from Amsterdam to Paris. Yes. Traffic lights on a highway, in the middle of a city Sounds like the beautiful little town of Bad Oeynhausen, which I came to loathe(a bit) - I used to drive several times a year from Amsterdam to Krakow(~1300km) and literally the moment you got off the ferry in Amsterdam you were on the motorway literally all the way to Krakow....…

Reminds me of Luik/Liege in Belgium just across the border form Maastricht. It's far worse there especially when you look at how poor the construction is there and how high the pollution seems to be. You can see that city has suffered immensely economically. The journey through Maastricht over the highway generally wasn't all that bad, traffic would generally flow remarkably well. I think the primary concerns to put…

Interesting. I found Liege to be a charming little city. The Calatrava train station is one of the most interesting stations in Europe in my opinion. The bike path along the river is quite nice as well. I didn't perceive the town was suffering economically. Would you mind elaborating? Genuinely curious.

Isn't it more literally 'bath'? I thought the English word came from it.

Yes, but as a town prefix it means that they've got medicinal springs. I think that's called spa, isn't it?

Not a German speaker, but is baden the plural form then? I feel sometimes spa towns have baden in the name and others are just "bad."

Above 22Mph it is the tire noise that the most dominant source of noise pollution by cars. In most noise pollution scenarios EV's will change nothing.

Most city driving is below 22mph, so this is a useless bit of info. Living next to a stop sign in San Francisco, 100% of the traffic near my place is at speeds less than 22mph and I can assure you that the tire noise is completely inconsequential compared to the revving engines and obnoxious exhausts.

Living in Boise's Downtown, I live next five lanes of traffic drive 35 or 40 mph on an asphalt road fortunately not chip sealed, like many of Idaho's roads. The revving engines are bad, but tire noise is easily 50 dB 15 meters off the street.

The plural would be "Bäder", but I'm not aware of any town using that plural form. It would be very strange, too, because a town is a single entity.

Baden-Baden is the only one I know that comes close, and https://en.wikipedia.org/wiki/Baden-Baden#Name explains how it got that name. It's not the spa prefix, but part of the name proper.

Also, "Baden" is a region in the south-western state of Baden-Württemberg that probably has lent its name to other towns.

It is home to one of the two big dialect families in Baden-Würrtemberg: Badisch, the other being Schwäbisch/Swabian.

Well there's also Wiesbaden in Germany, which is pretty well known. There are some others as well closer to the Czech republic.

Just 850 million euros of public money to build a mile and a half long tunnel under downtown! (Under a billion euros total.) A bi-level tunnel, with separate express and local levels, and four lanes on each level. By contrast, the SR99 tunnel in Seattle was about 1/3 longer, cost $3-4 billion, depending on how lawsuits shake out, and has half the capacity (two levels with two lanes each). The Big Dig in Boston was th…

So like, what's the deal? Is that level of efficiency common in Netherlands/Europe or were they just as surprised? What are they doing that they can end up with such a disparate outcome with regards to what most people expect from an ambitious public infrastructure project like that? Like, I don't even think it's cynicism at this point that when you see they want to do something with the MTA or the Metro, they'll say…

It’s different legal and contracting culture. Britain is also a common law legal system and our projects are typically way less efficient than mainland Europe. E.g the most expensive TGV the french have built was about 5-10 times cheaper than HS2. It’s not land acquisition costs that are causing the difference as these only account for about 3bn of the 80bn budget. It’s not difficult terrain either as the french TGV med has more bridges and tunnels. It’s not labour costs as we share the same labour pool as the french so we could attract loads of french digger drivers if we paid 5x more. My theory is that UK politicians and managers are more risk averse so the cost of the risk gets pushed down the chain of subcontractors and every time it jumps down a level it multiplies. I also suspect that the french will have a government department for building high speed lines with a continuous culture and body of knowledge stretching back to the 1960’s with engineers on staff. Whereas in the U.K. the team will be assembled from various consulting engineering companies and everything that is learnt on the job gets lost when the team disbands at the end.

And I can assure you that most of the car noise where I live is tire noise (typical speeds around or exceeding 40 km/h which is the default limit in urban areas around here) Especially when the streets are wet and/or when it's studded tire season (that is to say, about five months per year). I realize that both of those conditions are almost completely alien to Californians, but there is a whole world outside the Sunny State as well!

Most car noise on high speed roads is tire noise, not engine noise

GP comment sounded like it was in a town or city (school nearby), where average speeds are lower and "high speed roads" are not the norm. In towns and cities, engine noise definitely dominates tire and wind noise, especially revving from stops, and would thus be vastly improved by electric vehicles. Not to mention smell and air pollution which are always worse in fossil-fuel vehicles.

I live in the center of a city of ~230,000 and the top contributor to automobile noise absolutely seems to be tire noise even at normal urban speeds of roughly 30 to 50 km/h. I suppose traffic is generally calmer and traffic flow smoother here than in, say, large US cities or other parts of the world where people's driving habits are more aggressive. On the other hand, wet streets and studded tires amplify tire noise by a large factor (and most drivers insist on studs even though urban conditions almost never call for them, and non-studded winter tires would be a more appropriate choice).

Same. My street is (steeply) uphill, so it's a mixture of exhaust smoke, huge revving, burnt rubber, tire skidding, burnt clutch... A veritable bouquet, at 8h30 in the morning.

All at <35km/h. Can't open my windows before ~10am.
