Start Stop Idling

Icon Heading

Accelerate, Brake, Idle, repeat, repeat, repeat...

Every acceleration of a combustion 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 and suspension. Idling vehicles can produce twice the emissions of a moving vehicle.

Every morning and evening, millions of vehicles accelerate and brake hundreds of times over short distances and idle for extended periods of time. This is preventable.

The number of times a vehicle accelerates and brakes can be significantly reduced if traffic lights are optimised to hold vehicles stationary (for two to three minutes) until the section of road ahead is clear to drive on.

Managed correctly, this would have little impact on driver journey time but would significantly reduce the number of times each vehicle accelerates & brakes and would provide obvious opportunities for drivers to switch off their vehicle engine rather than idle.

A significant reduction in vehicle emissions may be achievable if we reduce start-stop-idling during peak times. We’ve engaged Wandsworth Council to support our request for TfL to pilot our Start-Stop-Idling pollution solution on a section of West Hill in Wandsworth (Putney High Street’s dirty big sister).
