Not necessarily. Just remove the brain first at the source and leave the brain until last at the destination.

...and boring to sit or even stand in the machine for hours, and possibly you'd be faster by train. Besides, it's kind of OT.

I have great benefit of seing wich cars are parked and wich are about to drive in mixed street trafic, in Norway lights are lit automaticly when the engine is turned on.

Yor're probably right. However, even up here in the snowy winter hell called Norway, where seatbelts have been mandatory for ages, almost 10% of motorists don't use them, so it's not the entire explanation. Must admit I'm an offender myself; from time to time when I go a km or so in a 30 zone, I neglect to fasten it. Don't know why, really, and I tell myself I should use it. Stupid, I know...

I remember watching a Discovery series about traffic safety a few years ago. One of the claims made was that if you widen a road by a foot (I think...), average speed increases by 2 mph (again, this is my personal recollation...). Thus, it doesn't take long before a safety benefit from an improved roadway is eaten up by an increase in driving speed. Quite interesting, even though I don't think we should stop improving roads because of this... But if true, it shows you need to think carefully about how to improve roads, simply making something that's more efficient doesn't necessarily improve safety.

That isn't so weird. If you have to pass an other car on a small street with just a few cms difference, you'd also not do that with 50km/h. The more space you have, the more comfortable it will feel to pass at a higher speed. That's a natural reaction. That's also the reason why speeddifferences between vehicles so much more influence have on traffic safety that speed itself.

I think is much-much more important to creat 2x1 roads with spearated intersections, such as there are around - for example - Barcelona.

These roads are NOT highways, and there are only 1 lanes / direction, BUT there are no perpendicular vechicles coming onto the road and everyone turning on/off has an easier way.

When you are going in the main section, you have priority over everyone else. Long straight sections and a higher (possible 100-110 kph) speed, ringroads around towns, no railroad crossings allow for higher capacity as sell.


Below you can see:
- a highway
- a main road with separation (upper left)
- a high speed railline
- a regular rail line

I'm not saying it's weird, on the contrary, I think it's quite understandable. However, feeling safe and actually being safe are two different things. The main safety problem with an undivided road is head-on crashes, and they become more severe with increased speed. If memory serves me right, this was one of the main suspects when it came to increases in road fatalities. Roads seem safer, cars are safer, thus, we drive faster... and the safety benefit of the improved road vanishes. The same was said regarding T or X junctions: you may improve them, but unless you remake them into roundabouts or grade-separated systems, you won't really reduce the number of serious crashes. Roundabouts are interesting, since they often lead to more collisions, but fatality and serious injury rates drop.

What do you think of this idea? "share space" no signs, ONLY the Priority to the right rule.

Hi!



http://en.wikipedia.org/wiki/Shared_space

for the lazy ones

Some euro countries try this out and even in USA and Australia!

Seems it works...do you think you can adapt such a concept to a bigger city like LA or New York, Berlin oder London????

Its called pedestrian or limited-access street. Very old concept.

I think it's good for places with nearly no traffic, such as historical city centers or shopping streets.

Otherwise I think it's a stupid idea. Make it look like Africa (no signs, markings or road layout) so everybody doesn't know what to do and has to slow down so bad that it's "safer".

I recently heard a radio show dedicated to the blind and sight-impaired on BBC Radio 4 about this topic. Many in the sight-impaired community are quite concerned about the lack of a curb which helps them determine where the pedestrian zone ends and the car/bike area begins.

I like the idea of this. It can mean instead of having to wait at lights then speed up and slow down you can carry on through at a slow speed but stop much less. Pedestrians no longer have to wait at lights but feel it is safe to cross in front of cars who are happy to slow down for them. It is simlar to the occasions when traffic lights fail, as nobody has priority everyone slows down and proceeds with caution while cooperating with other road users, then everyone passes the crossroads quicker.

Sorry to pick in on just a part of your post, but as far as I'm aware, there are usually still signs on intersections which indicate which road has priority (Stop-signs, Give Way signs or priority diamonds). Those signs are to be followed if the lights are defect. And if there are no signs, there's the priority to the right rule (talking about Belgium, will certainly be different elsewhere).

In the UK we don't tend to have that. Often one road will be wider than the side road and have separate lanes for people turning right so you could assume it has more priority but there is nothing to say it has. Whenever this has happened the traffic flows better and you don't find yourself sitting at a red light while nothing moves on the intersection. Generally we would have priority to the right like at a roundabout if there was no signs but as there is no overall rule everyone treats it with caution and moves over slow enough not to cause a collision if someone does something unexpected.

You've put the whole URL between youtube tags. You should only put the code after "http://www.youtube.com/watch?v=" between those tags.

Horrible accident, that guy is pretty lucky to survive without a stratch.
