20mph online petition

Re: 20mph online petition

knowing you cannot exceed 20mph means you can't accelerate as fast as you did previously. This adds to the time taken for the cautious drivers as the gap between cars that they require will become even larger.

RJK conveniently ignored by earlier comment. Being hit by bus or lorry at 20mph and you're dead. Are we slowing these vehicles down to 5 mph or is the safety aspect just a smokescreeen?

I ignored it because it was moronic.

Re: 20mph online petition

surely it'll be a slower motion version of 30. So the cautious drivers should love that

Yes, slower oncoming traffic means its better for pulling out of junctions and traffic flow. As Gabalfa roundabout is when knobheads aren't flying around there at 30+.

Re: 20mph online petition

That petition isn't worth a wank anymore as you got people who pissed at Covid lockdowns 2 years signing just to "get one over" on Drakeford.

Seeing some people lose their collective minds over a 10mph reduction in certain areas has been hilarious. If it angers the absolute melts then I hope it stays around.

That makes no sense at all. You couldn't previously exceed 30mph, it's the same thing, except slower.

Car coming out of junction onto 30mph traffic knows he/she can't go over 30mph pulling out, but has 30mph cars going each way.

Car coming out of junction onto 20mph traffic knows he/she can't go over 20mph pulling out, but has 20mph cars going each way. So it's easier. They're going slower. Cautious drivers will love this.

The people who won't love it will be the people who rev the shit out of their cars to zip out of a junction really quickly over 30 will be caught short. But it'll mean those people shunt into the back of queuing traffic less. Another benefit.

Re: 20mph online petition

1 or 2 minutes added to journeys

So this morning on Cathedral road - I was sat in traffic for 20 mins - due to the new bus lane issues. Sat in a vehicle wit my engine running - like everyone else - dont you think that the resulting traffic jams will result in more air pollution ?

ps - what is the total cost the the economy of delayed journey times ?

why would 20mph speed limits make more traffic jams, or more cars on the road?

of course it makes sense you're just not thinking clearly.

in a flow of traffic at 30mph the gaps between cars will be greater than if they are travelling at 20mph. All the dithering idiots waiting at junctions to join the flow of traffic, the gaps between cars are now going to be smaller, meaning they are less likely to join the traffic in an expeditious manner. Instead they'll wait for longer waiting for a gap that they feel comfortable joining.

density wave theory, look it up. its what causes bunching on motorways.

Some still will be some won't the difference between the fast and slow will be greater making it harder to judge and more crashes at junctions.

At lower speeds densities become greater resulting in a compound effect, slowing down vehicles even more, resulting in greater densities.

then why do they lower motorway speeds at times of high traffic volume to avoid this type of traffic jam?

anyone who has ever driven a car can tell you that it's easier to join a flow of traffic at 20mph compared to 30mph.
apart from anything else at the more relaxed pace of 20mph I've noticed that people drive a lot more politely and are more likely to let people out.

by your logic should we increase the road speeds to 50 to help nervous drivers pull out of junctions?

It's easier to pull out into slower moving traffic, because you can reach their speed more quickly.
