M1 to be 50mph around Sheffield??

[Lounge Jay 10]

No its not,its whats to come from other towns i suspect.Its easy to blame this goverment but it was the last one that started the road to pay per mile and its coming no matter who gets in,its just a matter of time.

 

No what I'm saying is that the government want to increase the speed limit on the motorways to 80mph; doing the opposite(needlesly) on "their bit" of the M1, SCC are sending a petulant message to the Tory led government, a message of Sheffield is Labour, you dont run Sheffield.

its just another example of local councils making changes to roads when they arent qualified to do so.

 

what happened to roads and speed limits being set by highways engineers?

The M1 is not within Sheffield Council's control. It is operated on behalf of the Government (Department for Transport) by the Highways Agency.

 

That's why SCC are asking the Government to reduce the speed limit. SCC can't make them.

 

So, there 's nothing petulant in it or anything about sending a message to the Government. The Government require SCC to produce an Air Quality Action Plan, because pollution has reached an unacceptable level. What SCC are doing is asking the Government politely if they would consider lowering the speed limit on the M1, to help tackle the pollution issues in the Tinsley area, a good deal of which results from the Government controlled road.

Well shut my mouth. Thanks for that. Standing down

when you say REACHED an unacceptable level,since when?

 

Cars kick out alot less crap nowadays and drivers are activily choosing more efficiant cars so give us the run down of when it was acceptable and when it changed to unacceptable,im a little confused but as you know thats not difficult

I see you choose the easy posts to answer and ignore the ones difficult to defend.

without name calling please enlighten us how this below is wrong and how SCC think they can get the traffic flow to be fluid at 50 mph when taking these factors into consideration,maybe they have and emmisions arnt really the goal.

Thats if the traffic would flow at 50 mph but it wont.All speedos are fast for a start by about 4mph at 50 so straight away you can knock that off,then take inot account few drivers will drive bang on the limit so knock a few more mph off ,now your getting nearer the 40 than the 50 and this is the M1 were talking about!

Can't quite believe the amount of conspiracy theories here. The speed limit of 50MPH is purely to reduce the air pollution in the Tinsley area, which due to various factors, including the profile of the viaduct, has some of the worst air pollution problems in Europe. The concentration of Nitrogen Dioxide in the area is well above the maximum limit set for public health.

 

Fuel usage to overcome air resistance is proportional to the square of the speed, so at 70MPH a vehicle will emit 4900 units of air pollution. If speed is reduced to 50MPH the the same vehicle wil emit only 2500 units of air pollution. That's almost half the amount of pollution. It will certainly make the atmosphere much safer for people living in the area. What's the alternative? Evacuate Tinsley and displace the population to somewhere with an atmosphere that doesn't breach public health limits?

What about a huge extractor, or humidifier along the length of the bit of the M1 in question? Take all the pollutants up, up and away!

Maybe that's what the cooling towers were for. I knew we should have kept them.

Have you not read any of the thread?

 

How do you suppose SCC will get the traffic to flow a fluid 50mph? Lifes so simple to some isnt it?

We are not talking about vehicles on a machine,we are talking about normal drivers alot with low driving standards who can barely drive in a straight line never mind a constant 50mph,it just will not happen and the result will be MORE immisions!

It changed to being unacceptable when SCC declared the whole city an Air Quality Management Area (ie when certain pollutant levels reached trigger points). That meant that they had a statutory duty to produce an Air Quality Action Plan, which sets out how they will try to manage the pollution levels.

 

There was a 50 limit over the viaduct for a substantial length of time when the strengthening works were being carried out. Did we notice any great difference in traffic flows?

There are plenty of major roads which have 50 limits and traffic flows just fine.

 

50 is the standard speed limit for urban motorways.

yes, the queues joining the m1 were muuuuuch longer and slower.

 

was fine again up until the new signals on the roundabout that have made a total mess again, and change their program almost daily
