I thought most phantom traffic jams are caused by a knock on effect when tailgaters break. Does a 10mph speed reduction really cause people to back off and tailgate less? Or are they less scared by their tailgating and don't feel the need to panic break so often?Quote:
To find out why, research the cause of phantom traffic jams.
As you say uniform speed = better flow. Dropping the speed limit =/= uniformed speed, just variable speed with a lower upper limit.
as to it being faster to go at 60 fine at say 8am when there is traffic but at 10pm its not hence why i have no objections to managed motorway like on th m62 and m42? round brum
I suspect the pollution levels would be greatly reduced by simply putting average speed cameras along that stretch of the M1. This would have the knock-on benefit of reducing the average speed along that stretch which (given that slower traffic needs less inter-vehicle space) would mean more vehicles could use it at once. Hey presto, congestion reduced.
This wouldn't pan out though, because people tend to say 'that road's much clearer than it used to be so I'll use it instead of another one".
It's also interesting to compare the land use vs people carried of a motorway vs a rail line. Cars - especially low occupancy ones - are a terrifically inefficient way to move people, in terms of land and energy / fuel use (hence pollution).
Probably been said already but its worth saying again...
Increase the standard of driving!!!
It strikes me as a sneaky attempt to implement more "Managed Motorways" (as per the M42 and M6 near Birmingham) and nothing whatsoever to do with a several year "trial" (FFS!!!) on whether emmissions will reduce (which they will do anyway due to improved car, and hopefully HGV, technology).
As an aside, i find it sad that in these times of austerity and cutbacks, the Highways Agency are operating from an office in "The Cube" in the middle of Birmingham - which isn't exactly the cheapest the place to be :(
I drive 20 miles on the managed M62 every day. When they were building it (2 years of roadworks) it was limited to 50mph av speed and I was getting 65 to the gallon.. now its managed and usually set at 60/50 its dropped to 55ish. Prob my bad driving and the increase/decrease speed between cameras but if everyone did the same thing that's a fair bit of extra pollution going into the air.
They could move into your point, that would be a cheap place. :DQuote:
