THREAD: I’ve done a lot of interviews about low traffic neighbourhoods over the past few weeks.

The most common question I get asked is how do you know this will work? How do you know this won’t make traffic worse on other roads?

Here’s the truth: I don’t know.

Sarah 🍓 1/ You say you don't know if LTNs will make traffic worse on other roads. You should know that they do. The data from Waltham Forest confirms this. You can also see the increased congestion and experience increase #airpollution at many locations. Please speak to @rosamund_ElsFdn

LTNs are deliberately designed to make busy through roads worse. They make the most challenging roads worse.
