I live in an LTN. It was spearheaded by a couple of cycling blokes locally who lobbied local councillors for ages.
The LTN has divided our estate in half, totally blocking routes through (think of our estate as like an H, now it's blocked off on both sides just north of the horizontal line). Those on the North side have no turning circles at the end of their new cul de sacs and reversing out is a pain.
We are the leafiest estate in our area and all have big gardens and large homes. We also live beside the largest park in the borough.
Our cut-through traffic is displaced onto two roads around us. To be fair, these are the main roads, and were always busy.
When the LTNs were proposed, the "champions" made anyone expressing reservations feel ashamed and frightened to say so. They ascribe any hesitancy to "not wanting driver inconvenience" and putting "driving an extra couple of minutes" over "our children's right to play out safely". No kids play out. There's no need since there's a huge park and everyone has gardens. We got a lot of "its pure lazy driver selfishness and you hate the kids if you don't want this LTN". As a result, the people against the LTN were scared to gather; meanwhile, the "pro" big guns were having regular meeting with councillors and writing positive spin about the scheme on twitter and in the news. But on voting, it was still only 52 percent of those voting who wanted to keep the LTN. It's been made permanent.
The sacrificial streets were given no vote on whether they wanted the LTN, or whether it should stay. The people who live there are majority Asian families, the houses are much smaller than ours.
Yes I would like children to have safer streets. But I would like ALL children to have safer streets. Not just the middle class ones. I would like bypasses, routes to the motorway that don't drive through my suburb, large venues (football stadia) to have parking several miles away and bus people in, except for disabled badge holders. I don't believe in creating effective "gated communities " of privilege and then the council patting each other on the back for a "successful scheme" when our estate will never be the same in regards to the way neighbours view each other. And yes, I would like my route to work to once again take 15 min less, and not involve two dangerous right turns into heavily built up traffic on the "sacrificial roads", to get to where I used to get in 15 seconds. But that really isn't my main objection.
Attaching typical "pro LTN" judgement of the type we experienced locally.
