Rush Hour Pollution Solution

We’ve found a way to reduce rush hour vehicle emissions by 70% and we need your support to convince the Mayor of London and TfL to pilot it.

Like millions of Londoners, we live and travel in a Clean Air Zone, an area where exposure to air pollution means our children have a 10% reduced lung capacity. We refuse to accept that our children will grow up with lungs that are 4X smaller than their peers and their life expectancy significantly reduced because of the air they breathe as they travel to nursery/school.

Public Health England research shows that even the smallest improvement in air quality could hugely benefit children, yet nothing. No action taken by TfL or Wandsworth Council to reduce traffic pollution on West Hill (where the A3 meets the South Circular Road).

We decided to commit ourselves to finding solutions to significantly reduce air pollution our children breathe. We’ve taken a hyperlocal approach and focussed on a one mile section of West Hill, with a nursery, a hospital, residential apartments, houses, large council estates, a care home for the elderly and a school with over 1,100 children.

During peak times, the number of vehicles from the A3 traffic is greater than number that can pass through the traffic lights at the junction with the South Circular Road. West Hill traffic is slowed to almost a standstill. The usual two to three minute journey time is increases to around sixteen minutes. There’s a constant line of HGVs, coaches, lorries, trucks and cars, each accelerating and braking around forty times and idling for around twelve minutes.

Every acceleration of a diesel vehicle releases carcinogenic fumes into the air. Every time a vehicle is stopped, tiny bits of metal, rubber and oil are released from the brake pads, tires, suspension and road surface wear. 

We can significantly reduce the number of times thousands of vehicles accelerate and brake if three sets of traffic lights on West Hill are optimised to hold vehicles stationary (for two to three minutes) until the section of road ahead is clear.

Managed effectively, this would have little impact on driver journey time but would provide clear opportunities for drivers to switch off their vehicle engine rather than idle. This would reduce the number of times vehicles accelerate and brake by over 70%. Vehicle idling time could also be reduced by over 70%.

The reduction in air pollution would benefit drivers and pedestrians on West Hill and this solution could help to reduce traffic pollution on other roads that have high NO2 levels due to start-stop-idling traffic.

The people responsible for public health should be moving quickly to test and share all ideas that could significantly reduce vehicle emissions and public exposure. We're asking the Mayor of London to pilot our Rush Hour Pollution Solution on West Hill and we need your support.
