As to how to the variable speed will be managed, I missed your post on that, but I'm sure there are some obvious metrics and metering that can/is done today - traffic volume, speed etc. Perhaps something more predictive would help - inbound volume of traffic, road conditions, events, etc. What were your thoughts?
My thoughts are that it may work in certain areas. As no-one listens to speed limits that make no sense they would have to be imposed under stringent conditions, eg when there's a certain flow of traffic and should only be around those troublesome junctions. People should also be remind, perhaps using signs, that there is an accelerator on their car for a reason and to use the full length of the sliproad to join the carriageway when possible.
When things like the Newbury Show is on and there is a much larger traffic density on the road then that may again help as well although that's a bit far away from the troublesome area you mention.
Do not get me wrong, I am not disagreeing with you saying there is not a problem, simply that slashing the speed limit won't solve the problem - Which was what your original point was (you have since changed your views slightly, who says you can't be reasonable.
)
As proven (Biker1 you may be interested in this too) in one of the links showing that when the speed limits were raised and lowered by between 5 and 24mph (I think it was either 21 or 24..) that no real difference in actual traffic speed occurred and the deduction in speed limit didn't reduce accidents in those cases. It boils down to drivers will drive how they feel the conditions dictate and that's nothing that can be easily solved...place speed cameras you will just have people slowing down for them, average speed cameras on a regular dual carriageway will not wash with the motorists and many complaints will ensue...sure it'll make people slow down for sure, but will they be paying as much attention using their attentive abilities for shouting in anger at the cars in front?
P.s the changing lanes used to work, not any more I am told. I wouldn't risk it haha. Cruise control at 49 in those situations..
