when you see all the air pollution episodes in major cities, which lead to very frequent respiratory diseases, rhinitis, asthma ... (there is also for other more serious effects, asthma, cardiovascular risks and risk carcinogenic, see http://www.officiel-prevention.com/envi ... dossid=101 ), The decision to decline 70 km / h speed on devices seem sensible.
What do you think ?
Limitation 70 km / h on the device

The periph of Strasbourg is limited to 90 and 70 kmh following locations since 2-3 years ... is that this has had an influence on pollution? J doubt it ...
Should do some research ...
Ditto on congestion ... not on this to be more fluid at peak ....
And c 70 kmh low as highway speed ...
The engines of modern cars are designed so that consumption is minimal between the 100km 80 and 90 kmh.

Pollution in big city will not be solved by a speed limit.
This is the city rethinking ...
Probably commenceant by bringing people from work ... Or people's work ...
Yeah ok, what I say is a little light!
Well why limit has not 70 and 50?
Oh yes limit 50 Km / h is probably the next step, since our dear Parisian greens already imagine being able to put red lights on the device in 2050! ;)
In short, there comes a reflection, in a world where everything goes faster, the more time passes and the distances are getting longer! ;)

Hello
all right! more the gearboxes are not stepped to roll in 5 ° at 70 km / h; you have to downgrade and therefore consume more and therefore increase pollution. Knowing that the "free" speed can only be done outside periods of non-saturation and therefore infrequent except at night when traffic is fluid. It's the snake biting its tail!The engines of modern cars are designed so that consumption is minimal between the 100km 80 and 90 kmh.

Yep I sometimes say no bullshit
Otherwise about 2 years ago, there had been an even more "crazy" idea: the speed limit throughout Strasbourg to 30km / h, that is to say the whole city in "Zone 30" ... therefore a huge hoax green for the reason we just say ... at least with respect to pollution and vehicle consumption!
This has been a kind of local referendum ... obviously rejected (over 60% I think).

On certain sections of the motorway, the speed limit is lowered from 130 to 110 km / h when a certain number of vehicles / hour is exceeded to "delay" the formation of traffic jams.Christophe wrote:Ditto on congestion ... not on this to be more fluid at peak ....
It works quite well and overall, it takes less time to travel a given distance 110 km / h at 130 km / h 2 km of traffic jams in which it does not exceed the 30 km / h (and I think they pollute less, too).
Of course there is no miracle: when there are really too many vehicles, it jammed
On the other hand, the systematic reduction in speed, including at "off-peak" hours, is ineffective.

Yes Gaston. Mathematically it is valid this method!
And it is more and more frequent on the motorway via temporary indications of "recommended speed".
But I think it works well on long stretches of highway when a slowdown or cap presumption is detected at several tens of km ... against by a small ring road like the one in Strasbourg I do not know if the practice is really effective (or so must reduce speed drastically, it is already 70km / h automatically on certain portions of the Device of Strasbourg ... so ...?)
ps: another article on the subject http://www.lemonde.fr/politique/article ... 23448.html
