Cichlidae posted:We use it for our Geographic Information System, which is the base grid upon which we lay out all of our projects. It does need to be very accurate, at least as accurate as our surveying equipment, and as far as I know they do account for the Earth's curvature. I don't think they do, which is why there are individual grids for countries and regions. The curvature of the Earth is small enough then that it's not significant. The Netherlands uses a grid with its origin just north of Paris, so that all coordinates that are actually inside the Netherlands are always positive numbers. I imagine your grid having its origin in Pennsylvania is for the same reason. Cichlidae posted:For my purposes, though, all I really need to know about it is that if I try to export something to Google Earth, it all ends up clumped in Camden. Google Earth uses WGS84, which is not a flat grid but uses degrees/minutes/seconds and spans the globe. If you simply dump data from a flat projection into it (like the Pennsylvania-based grid) then your data won't end up in the right place. You'll need to transform the coordinates, which ArcGIS and other GIS software can probably do. Apologies if you already know all this, I'm far from an expert on projections but GIS is my job. What I do mostly is processing our surveyors' measurements of newly completed or altered bits of highway. Me and my collegues then process the measurements into a complete database ready to send to the highway authority. They then integrate it into their main database that covers all highways in the country. That database contains almost every object belonging to the highway authority, including the pavement, lamp posts, guard rails, pavement markings, traffic signs, sewer pipes, traffic lights, distance markers (every 100 meters), as well as all the underground cables to power and control everything, all in x, y and z coordinates. Then there's the attribute data for every object, specifying its exact type (what kind of traffic sign, which type of lamp) as well as information like when the object was installed (if known), and which district it belongs to. It's pretty comprehensive as well as a pain in the rear end to fill in everything completely and correctly, and the highway authority is pretty good in spotting any omissions or errors when we submit the database for a newly completed stretch of highway.

I just don't think it would be built like that right now, the pic I provided is the line they're planning here in Groningen, the Netherlands and my only live tram experience has been using them in-country and being on the business development side at an engineering firm for a bit. Ah, the political clusterfuck that is the Groningen tram line. A majority of the city council is now against the plan if funds are not found. At this point, however, the city itself is in debt and the province does not want to give them the money either. A friend of mine is vocally opposing the plan, and has been interviewed by various media, where he claims that the numbers were fudged to make the benefits of the tram plan seem much higher than they really are. This led to a shouting match with the councilwoman responsible for the plan on Twitter What street is that artist impression of, by the way? The entrance to the campus? I can't quite place it. Anyway, I like trams as a mode of transportation, but in Groningen I am worried that it will replace bus routes, which serve a much larger area due to having more stops. I doubt the city can afford to maintain the tram, as well as keeping bus services as they are now. SixFigureSandwich fucked around with this message at 18:03 on Jul 17, 2012 |

The Netherlands has started using section control on the A2. Cars are photographed when passing under a portal entering the section of highway, and is photographed again exiting it. If the time in between is less than the distance divided by the maximum speed, then you have speeded and get fined. I also encountered this method in Austria, in a construction zone, and everyone actually adhered to the max speed for once. Is this used anywhere else?

Interestingly, as far as I know they're actually illegal in France. Illegal to the point where companies like TomTom had to release a patch to remove this information from their navigation sets for people in other countries who were planning to go to France.

Cichlidae posted:After a time, we would probably do dual guidance, with radio transmitters on each sign to relay the same information to the car as a driver sees. I say probably, because at this point, the car is getting redundant information (since it can already "read" the existing signs) But why would you need radio transmitters if the cars can read ordinary signs fine? Regular signs are probably more reliable and durable, and I think there will be people driving cars for a long time still, if not forever. Think oldtimers, emergency vehicles, recreational drivers, malfunctioning cars which have reverted back to manual control, etc.

Cichlidae posted:You didn't read the rest of the paragraph. Unless radio transmitters are massively cheaper than signs (which they may very well be on freeways, where a lot of the signs are made useless by GPS anyway), we'd keep signs up until it was 100% automated drivers. No, what you said was that there would be little point in switching over until 100% of all vehicles are driverless. But since driverless vehicles need to be able to read regular signs anyway, I don't think there is a (technical) need to switch to radio signals at all. It could well be more cost-effective though, I don't know. In fact what I can see happening is that highways eventually become off-limits to manually controlled vehicles, but smaller roads allowing them, for those people who can't or won't drive an autocar.

Cichlidae posted:Speed tables or raised crosswalks are a better bet. And yes, humps are at fault. If a cop or ambulance or fire truck is going 60 mph to get to an emergency, and they hit that bump, who's to blame? The driver, for driving at a speed unsafe for that stretch of road. If I take a sharp turn at high speed and crash into a tree, I can't hold the government liable for putting a bend in the road, so why are speed bumps an exception? Assuming there is a sign indicating the speed bump, of course.

Speed bumps can be badly constructed, and in those cases I can see why a government could be held liable for damages. But still, there are many reasons why it may not be safe to drive the speed limit on any particular stretch of road, depending on traffic situation, weather, your vehicle, and other factors. I can't help but feel that speed bumps are held to a higher standard here for no real reason.

After 5-10cm of snow in the western and southern parts of the country, the Netherlands just broke its record for traffic jams. The previous record stood at a total of 975km somewhere in 1999, today we managed 1007km, compared to about 200km on a normal tuesday morning. I decided it was a good day to stay off the highways and bike to the head office instead.

They sell it to the police, as well, who use it to figure out where lots of people drive faster than the speed limit. Mobile phone data actually suggested that the 1000km of traffic jams here last Tuesday was actually nearly 4000km, because the 1000km figure only counted the highways.

Agricola Frigidus posted:Laying down new tracks or even expanding existing ones is a nightmare in Belgium - population density of around 300/km². It's enormously costly, there's loads of NIMBY involved, no politician likes evicting people... Also, there's still a bit of an economic competition between Belgium (Antwerp harbor) and the Netherlands (Rotterdam harbor) - for example, despite the tracks already laying there, there is no train traffic through the Netherlands between Belgium and Germany - all existing train traffic has to move via the Liège-Aachen line, instead of via the so-called Iron Rhine. I thought an agreement was reached a few years ago to re-open the Iron Rhine route? Did that fall through after all?

Jonnty posted:This is kind of my point - I'm aware of all the weaknesses of European (and British) railfreight, and the reasons why it's not popular. But if you're a central authority and you've set dealing with a lorry problem on a road one of your policy objectives, then it's surely reasonable to consider roadfreight restrictions/tolling a point-to-point freight service to a more central location(s) to get rid of the bottleneck. Even if it requires subsidy, it might end up much cheaper than an upgrade of the road along with, as you say, saving on wear and tear, which people forget so often - although governments shy away from this as they apparently find subsidising the road network much more palatable than subsidising the rail network. Transporting things from one place to another is actually a pretty decent chunk of the Dutch economy, and restricting freight trucks might cause them to go to Antwerp or Hamburg instead.

Torsion forces generated in S-curves were much higher than anticipated, leading to cracks around the articulations between the car modules. Subsequently, hairline cracks were found in the joints of the aluminium bodies, which could cause the roof to collapse in the case of an accident.
