Pretty sure ambulances and police would have transmitters that make the bump not activate.

Electronics fail all the time.

Agreed. If I designed such a system, I would try to make it so that if power failed, or the speed radar failed, or anything failed at all, it should NOT activate. I.e. "locked into place" should be the default state unless a magnetic coil is powered, which pulls the support out, or similar.

I'm pretty sure the reason that thing was in the news recently is that it has just been tested over a Swedish winter, and as I understood it it came out OK.

Edit: A google-translated excerpt from the Swedish transport authority's report on the project, looks fairly promising but seems like they are not rolling it out on a big scale yet.

quote:

The project aimed to develop an active speed bump that makes it possible to combine good accessibility and safety for professional drivers with low speed and a safe traffic environment for vulnerable road users such as pedestrians and cyclists.

The aim was also to eliminate the disadvantages and problems identified in previous tests with active speed bumps such as

-lack of resilience to strain from passing traffic
-lack of durability against environmental factors such as gravel, salt, snow, moisture, etc.
-environmental noise disturbances

The project was conducted during the period 2010-01-01 - 2011-02-28 and included development and testing of software and electronics, testing in the traffic in Linköping and evaluation of tests.

This solution can in the future serve as a tool to create safer traffic environments where other solutions for speed reduction are not appropriate (for example due to high traffic volumes or extensive commercial traffic where the bumps are a health and safety problem).

My wife and I just came back from our honeymoon in North America. We were due to drive from Toronto up to Quebec City and back for a little road trip (I don't drive so it was all on her). After seeing how people drive over there, she was all nervous, and bailed on the plan and we stayed in Toronto all week instead.

It was the same when we got to New York the week after. We couldn't believe how mental everything was. People overtaking in any lane they wanted. No hierachy of slower lanes leading up to faster lanes for overtaking. People doing all sorts of poo poo at the wheel that if anybody did in Europe they'd get hosed for and massively glared at by all and sundry. Turn right on red scared the crap out of us, as pedestrians.

It was definitely an experience...

You don't mention which country you're from, but I assume it's not in southern or eastern Europe. People there drive way crazier than Americans. Try Istanbul or Athens, for example. But the bright side is, you get used to it! You'll be just as bad yourself after a few weeks in that environment.

Perhaps Germany has sovereign immunity. I know we've waived ours in Connecticut, because we get sued for every little thing. The most recent occurrence was when a tree fell on someone's car on the Merritt Parkway; we inspect the trees regularly, but it had rotted in the meantime and fell over.

Nah, the German state doesn't have sovereign immunity, not according to Wikipedia anyway. (I thought that concept only applied in old-fashioned backwards monarchies like Sweden, where the regent cannot be prosecuted, but apparently the US fed government has that, too?)

I think you can chalk it up to different concepts of how to keep the state from making crappy laws. In most of Europe, you as a citizen cannot hold lawmakers liable for not disallowing dangerous behavior. I'm sure there's a Latin word for this... If the state makes it legal for you to do a stupid thing and get hurt, you have no grounds to sue because you are still responsible for your actions. There is generally some mechanism to revert laws which are unconstitutional, but it doesn't necessarily involve neither courts nor damages.

But, on the other hand, if the state itself breaks a law, causing damage to you, you can sue for (actual) damages.

TL;DR: Germans can't sue the state for making it legal to go fast, but not because of sovereign immunity.

Wow, now it makes sense why they call it 'sovereign.'

If you know about German law, maybe you can confirm/deny what I heard once. In the US, if I stole a car, then got T-boned by someone who ran a red light while making my getaway, they would be legally responsible for the accident and I could sue them. I was told this wouldn't happen in Germany. Is that true?

I'm not really an expert on German law, but I agree that it looks weird if your stealing the car has any bearing on who's held responsible for the accident. That doesn't sound right. Usually this kind of laws are pretty similar across the EU.

I know for a fact that the other driver would be held responsible in Sweden, where I live. You're both committing crimes while driving, but only his reckless driving has any bearing on responsibility for the accident. Ultimately, what matters is how you drive, not how you came to be on the road in the first place.

In the end, he would probably be arrested either for reckless driving (loss of license and up to 2 years in prison if anyone was badly hurt), or involuntary manslaughter if you die. And his insurance company would cover damages to you resulting from the criminal case; there is likely no civil liability even though he's at fault. These would be mainly actual damages, such as cost of new car and rehabilitation, and loss of salary if you're hospitalized, but also some small compensation for "pain and suffering" (in the order of 230€ per month).

If you caused the accident while driving a stolen car, you'd be in a shitpile of financial trouble due to not having insurance, though. The other guy's insurance company would pay his expenses and then sue you in a civil case, as I understand it.


And that crap about "attractive nuisance" sounds like a lot of money down the drain...

I know things the GPS doesn't for example that friday night is not a good night to use the A4 southbound. Some navigation software tries to integrate this information but by all accounts it is still lacking.

I'm continuing this derail. Sorry, but navigation is a fun subject!

Fun fact: You phone operator always knows where your phone is. They have to know, otherwise they couldn't route calls to you. This info can be collected for one or all subscribers via what's called a Mobile Positioning System.

Some telecom operators (at least in Sweden, I don't know how prevalent this is elsewhere) will collect this location info from their network (and presumably anonymize the data). This location info for every subscriber is then correlated with geographical info on location of roads. This way they can find out where traffic is slow without even anyone on the road using a GPS! The operator can then sell this real-time information to GPS software vendors, who may send out traffic alerts to GPS owners. This is one of the services you won't get on freeware nav software. Although for instance Waze does a decent job of the same thing by checking on speed of their own users, they have too few users in my city to make any useful predictions for my travel time.

Phone networks are fun!

Am I a horrible person for not having much sympathy for people killed by trains when there's at least some sort of sign or bell ? It seems like most of the times cars and trucks and even people are creamed by a train it's some idiot who knew full well a train is there but impatiently tries to beat it. In a rural area put up a highly visible sign along with the correct road markings. In more built up areas make sure there's flashers and maybe a gate. If fatalities happen after that, it's suicide not a dangerous crossing.

I just saw on the news today that there have been four people killed recently by trains here in Sweden, all wearing headphones. The train drivers had all sounded the signal, but they were apparently not heard. The last victim was an 11-year old girl, who was hit by a tram yesterday but thankfully survived. The Swedish Transport Administration just went out and recommended that people should avoid wearing headphones in traffic, though there is not (yet) any law against it.

So, flashers with bells might never have been idiot-proof, but considering the increasing amount of people listening to music, they are even less so now. Technology just gave us a new, improved, idiot...

The Newport Bridge was built in 1969 and has 63m clearance and a 490m span, about the same as the Oresund bridge (2000). The Storbaelt bridge (1998) has 3 times the span with the same clearance, but it's a fixed link and includes a tunnel section. Vasco da Gama (1998) has 45m clearance and a 450m span.

I can't find many other open-water bridges with clearance heights on Wikipedia, but that's a good selection of what you'll need for typical 21st century traffic. (Newport is right next to a huge navy base, so it's tall for its time). For a bit of perspective, the span length of the Storbaelt means it can accommodate 21 Nimitz-class supercarriers abreast.

Might be worth noting that even the Storbaelt bridge can't accomodate the tallest cruise ships. A couple of new ships were built in Finland a couple of years back, and in order to get them under that bridge, they had to make a custom-made smoke stack that could be collapsed. And even then, they had to pass the bridge at speed in order to clear it (thanks to the squat effect)! (Yes, sounds terribly dangerous, and they did cordon off the bridge for the first (night-time) passage.)

They aren't used very much because they have to be replaced often but rubber flange fillers are used. Generally not for tram tracks, more for railroad crossings.

Cool, thanks, now I could google "rubber flange filler" and find out more. Was missing the proper term for it.

I found this in a comment on a traffic blog, so take it with a grain of salt, but it seems like flange filler is not practical for trams. =(

quote:

Flange filler: Zuerich & Basel both tried it out, and it works for train tracks where train traffic is occasional (3 -5 times per day), but tram tracks have a different geometry, and the hard rubber gets compressed too often and crumbles. VBZ (Vertrieb…zuerich) did extensive tests over many years, and finally they had to conclude that it was a no-go. If we have similar types of wheels, he predicts
the same result.

I lived in a place for about six years on and off that had no posted speed limit on well maintained rural roads. I found that the speed drove at was highly dependent on road conditions. A nice sunny day during the dry season on a gun barrel straight section of road? 160-180kmh in my work v6, 190-210kmh in my personal v8. Regular road during the wet season? About 160 would be the max I was comfortable with.

About eight or so years ago they did a 85th percentile on the rural roads and dropped the limit to a maximum 130kph, though there is a shady agreement that the territory police won't bust you for less than 160 unless you are doing something pretty dumb, or are on their shitlist as an arsehole.

The current government is implementing a public transportation system named METROBUS,
[...]

Many people here think that it was a terrible idea because it takes one lane off from the standard 3 on each direction, so cars have only 2 lanes to work with, and that this system is always overcrowded at peak hours, so it is normal to wait for the 3rd of 4th bus to arrive to finally get in.
[...]

Is this really viable for a large city like Mexico City? I know I'm not giving much information on this but maybe you have seen this system work on another large city.

Istanbul (one of the worst traffic situations in Europe) recently implemented this system, and are also incidentally calling it Metrobus. I've not used it, but people I asked when I was there seemed to think it was a pretty nice stopgap replacement for a subway line (which will never come). It seemed common for people to have to change between the Metrobus trunk line and local lines to get where they were going, or walk some way.

Edit: Here is a major Metrobus interchange stop. I was staying in a hotel overlooking it, and the buses seemed to run on a frequent schedule.
http://goo.gl/maps/xM319

Of course, if the buses are overcrowded, they need to add more buses, but that shouldn't be a problem, right?

Regarding lanes, the point is obviously to make sure the buses run faster than traffic, and punctually, to encourage commuters to take the bus, thus reducing traffic on the highway, so the remaining lanes should be enough. Whether that will work is a different story, but I can totally sympathize with the intent, particularly in Mexico City's overloaded traffic.

I'm not seeing what the point of the right of way signs are, in America an intersection like that would generally have no signage at all on the higher priority road.

Unless one road is an arterial, there is no need for any signs at all. Americans would (in some states?) treat it as a four-way stop, while most Europeans follow the Vienna convention and thus the Priority to the right rule. The thing is, European arterials are not always very obvious, so lawmakers felt a need to signpost them. That's the right-of-way sign, which is tiny and looks like this:

The driver knows he doesn't have to yield to vehicles coming from his right. That driver, in turn, would probably find a yield sign at the crossroads.

Sounds simple, right? Of course, most people don't pay attention to whether the road is the signposted as arterial, so you get lots of situations where a driver is going down a non-arterial-road that looks kinda wider than the other roads and assumes it's an arterial. In the town where I grew up, the right-hand rule was obeyed religiously, so such behavior would sometimes result in accidents.

Looking at Streetview, a cheap solution could be to convert the sidewalk on one side of the road into a bikepath, and the other side into a pedestrian route with no bikes allowed. Broaden the bikepath where possible, and add a railing.

That was my first thought as well. That solution does require widening the pavement on the bike side, since it currently looks a bit too narrow to have two bikes meet at reasonably high speeds. Would involve moving a few lamp posts on the bike side.

Not sure which is worse though, having no railing and risking running into traffic, or running the risk of falling head over heels over a railing, into traffic...

The fact that everyone cycles, or knows someone who does, means that drivers are more sympathetic to cyclists when they have to share space on the roads.

In turn, the cyclists are expected to respect and obey the rules of the road. You may be fined for riding recklessly, in the wrong place or jumping red lights. Police (often on bikes) will issue a 60-euro ticket if you are caught without lights at night, and you will have to shell out even more if any of the mandatory bike reflectors - of which there are many under Dutch law - are missing.

Depends, if it's in America or Canada where the cult of the individual reigns supreme, they will just drive it anyways, and probably speed.

New suburban concept (you heard it here first)

Roadless communities. Large underground garage on the corners of each neighborhood. Green space over garages. Each Neighborhood is a 1km sqare with 8 surronding a centralized comercial zone (Grocery, gas, restaurants). Freight-only road around inside loop, large commuter roads around outside loops. Smooth and wide walking paths to each propery (for moving, large loads)

Use a side-by-side for garbage collection and maintainance.

Maybe run a strip of commercial between each Neighborhood for other services.

Would you be looking at something like this, then?
Gothenburg's suburb of Hjällbo, a shining example of 60's social democrat planned communities.
Edit: Transport infrastructure starts at 16:30.

My favorite quote is probably, at 17:25, with reference to the light rail, "What I like best is that it takes you just a short time to get into [the] city, to do something. You can't do anything out there." Says a lot about the problems built into these suburbs.
BTW, those trams pictured are still running, albeit complemented by more modern ones with AC and such.

Yeah Swedish urban design is often classic Garden City, and only really works because the society has such a low gini coefficient, baked-in egalitarianism, and the tax base to build and maintain infrastructure. Unfortunately they never had a failure on the scale of the 50s and 60s era housing projects to convince them of the unworkability of high-density housing standing alone in a park in the middle of nowhere.

Hey, who said it ever worked? =) Well, apart from that documentary...
Right from the start, there was a huge problem with segregation, and those community centers they brag about in the video were mostly decommissioned by 1980. Nowadays, Hjällbo is populated mainly by low-income earners and immigrants, as the rents are fairly cheap (and it's all rental, more or less).
I guess you could trace the early segregation to where those residents lived before - in the city slums, which were demolished, as shown in the same film. They went from having no running water and wood-fire heating in a tiny slum apartment, to a modern but slightly anonymous apartment block, where the rent was hugely subsidized by the state so they could afford modern standard. They were still pretty poor working-class people, though, and it's stayed that way even 50 years later.

We don't really do it that way anymore, I think the last suburb to be fully planned like that was in the 1970s. The rest has mostly been "organic" growth.

The part in that video about excluding traffic from the city centre was a bit sad, too. When we arrived in Gothenburg by train, we found ourselves (as pedestrians) having to cross this:

That's about 100m from the central railway station.

Well, to be fair, there's a pedestrian tunnel + ground-level crosswalk 20m off in one direction (http://goo.gl/maps/6n52H), and a signalized crosswalk with generous-to-pedestrian timings 30m in the other direction (http://goo.gl/maps/alseu). If you did want to cross right there, that's fine with me, but you'd have to jump the fence, I guess.
On the bright side, they just converted one more NW-bound lane into bus lane, and as part of replacing the bridge across the river, that street is no longer going to be a thoroughfare. (Within the next 10 years of so.)
Other than that, I think the city center more or less works. There is some gradual narrowing of streets to make room for better bike lanes, and some new bus lanes being made, so drivers are complaining a bit, but with the recent congestion tax, I do think traffoc improved for the better.

While true, it is certainly possible to design an area where people can easily walk, bike, take transit, and own a single car for occasional use. The issue comes with values: when people consider it a fundamental right to be able to drive as much as they want and own as many cars as they want, no matter the consequences for society, the consequences for society are pretty dire.

So true. Having high fuel taxes seems to help a bit (over $8 per gallon makes you not drive so much), but that's all based on people accepting such a tax as not violating their basic freedoms. It all begins with values.

you're going to have a tough time convincing people to walk.
Yeah, seems like that's another one of the basic axioms of urban design. "People are lazy."
It's not like that design is impossible, you just need a fine-grained system of public transport, or a huge uptake of biking.
Though Tokyo certainly has the former, and people there do an awful lot of walking to/from the train/bus etc. Copenhagen/Amsterdam are good examples of the latter, why walk when you can roll?

How common are casualties in road crew workers, from getting run over? I get a feeling that it must happen all the time.

Anyway, here's a Swedish robotic arm that paints road markings. Apologies for the Google translation, but I think you can make sense of most of it.

http://translate.google.se/translat...icle3759897.ece

quote:

Longitudinal lines on the roadway have long been painted with machines. But arrows, speed limits and pedestrian crossings have been painted entirely by hand.

- Transport Administration have wanted to take a step to automate this process for security reasons. It's a risky job, says Per Ljunggren.

With the new robot, no human being needs to be standing in the road.

A nearly six-foot long robotic arm has been developed, which is mounted in front of a truck. Molten thermoplastic material (the paint) is pumped from a melting pot on the truck bed up to an extruder which is mounted at the end of the arm. Additionally, there is a vision system that shows where it will be painted. It is in contact with a library of symbols.

The two biggest roundabouts here have stop signs at the approaches. Is this actually not a good design?

A roundabout is supposed to be free-flowing. The entering driver should yield to traffic in the circle. In other words, if there is no one in the circle, you can just enter it, and not stop. It's good for traffic flow, fuel consumption, noise etc.

Stop signs in general just feel like a suboptimal compromise, thrown in when you can't afford a signal, or visibility is too limited for a yield sign.
