Amazing that LTNs are so controversial for some (see my excellent thread on 15 minute city conspiracies
) when they are basically about a usually dull subject of traffic control.
For years on my Hackney Street we had no resident parking so parking could be a trial, particularly as we are close to a train station - eventually after consultation - we got residential parking - and the street was happy with the traffic management intervention. Similarily, whilst speed cameras aren't universally popular, they have had an impact on speeding (I've accumulated about 12 points and maybe £500 in fines over 20+ years of driving ) and speed cameras do control traffic and have had an impact on safety.
I live next to a LTN , I used to use it as a short cut , I no longer do so, its no biggy.
