A🧵on congestion and boundary roads.
With new LTNs traffic increases significantly on some main roads. This added disruption is painful for all residents, including those who travel by sustainable modes or who live on those roads. This is part of the design. Here's how it works..
LTNs are behaviour-change programmes designed to reduce the number of unnecessary journeys. We need to do this because the growing decades-long issue of congestion is killing people now and killing the planet. Habits don't change overnight and almost always need a serious nudge
The main issue is traffic travelling through an area, but there is also an issue of unnecessary local trips. When the inconvenience of those trips outweighs the benefits of making different choices, the volume of traffic on borough main roads decreases. h2020-flow.eu/news/news-deta…
In fact, the only traffic mgmt interventions which have proven to reduce traffic volumes on main roads in urban areas are where network access is scaled down, as with LTNs.
Schemes across the world have proven this to be the case. Barcelona is just one. sciencedirect.com/science/articl…
The unfortunate reality is that in the initial months the pain will be felt equally on some or all of the main roads at certain times. The long-term gains, though, are fewer cars, less congested & safer roads, cleaner air and more attractive and inviting places to live and visit
It's worth repeating - schemes such as LTNs are the only traffic management interventions which have cracked the problem of reducing congestion without actually banning cars altogether
It is certainly true that on some boundary roads schemes have seen longer-term increases in traffic. This alone cannot be a reason to throw out an entire scheme if it is working to reduce traffic on most roads. Work needs to be done to improve those roads too.
Some factors could be due to long-term issues on those roads, such as illegal and even legal parking causing bottlenecks, roadworks or other traffic and construction projects. What follows is data collected on main roads from 3 London boroughs following implementation of schemes
Data included reveals both traffic increases and reductions. What becomes obvious is that in most cases traffic on main roads either reverts back to its normal volumes pre-LTN or actually decreases, sometimes dramatically, and on roads known for historic and chronic congestion.
Further data reveals that often where there have been increases, journey times have been only moderately impacted. The data is taken from interim reports and may not fully reveal recent changes and improvements. Where counts on same road differ, they're listed beside each other

In the end we need to decide whether we are prepared to work together for greener, cleaner, safer and more active boroughs. Are we prepared to tackle the clear and present danger Climate Change poses for all of us?
We need to decide whether reducing the number of collisions on our roads is essential. We need to decide whether we act now on the devastating impacts of air pollution. If we respond in the positive then we need to give low traffic neighbourhoods a chance.

Major transformational changes are underway in the Parks service. The pandemic has been a game-changer and our green spaces have never been more important. Climate change is the no1 challenge of our times and we must take bold and far-reaching steps to tackle it...
The Haringey Urban Forest. We are building the business case and the project plan for a massive increase in the Borough's canopy cover, potentially to 40% boroughwide. We will be focusing especially on areas deficient in cover.
The Urban Forest has the potential to be the biggest infrastructure transformation, changing lives, wellbeing, mental health, crime rates, flood risk and climate risk, in a generation.
We are transforming this Borough. The feet and the wheels are in motion. Sometimes it will feel slower than we wish and other times it will seem like it's all happening at once. As confidence grows we'll accelerate, but right now we need to take in determined stages...
This will become a walking borough. In the next few months we will be installing 11 new crossings across the borough, subject to consultation
This will become a cycling borough. In the next few months we will be installing nearly 40 new secure cycle hangars, subject to consultation
Some thoughts on the road ahead and what needs to be achieved.
An incomplete list. And not in any particular order right now. But all priorities.
And we're going to need some clear & comprehensive environmental key performance indicators with timescales to keep us on track.
Walking is crucial. We need to improve walking access to schools, surgeries, shops and open spaces
We need to urgently incentivise walking with wayfaring trails, connecting open spaces with each other as well as leisure & culture places
In 2019 77% of trips in the borough were by foot, cycle or public transport, only 23% were by car. With only 40% of Haringey households owning a car who is creating the gridlock on our neighbourhood streets?
Active Travel is a public safety issue.
In 2019 London had 25,000 reported collisions, almost 4,000 were serious with 125 deaths.
The only way to stop this is through collective action.
Active Travel is a public health issue, with health and life expectancy currently determined by your postcode.
