Hundreds of people gathered on Saturday (October 28) in memory of former Met police officer Claudia Manera, 51 , who was killed earlier this month in a crash with a lorry in Uxbridge Road.
Crowds waved banners and placards demanding safety in Uxbridge Road with some powerful messages including 'One death too many' and 'Stop killing cyclists and pedestrians'.
The march set off from Ealing Town Hall and ended at the Lido Junction, near Dean Gardens in Uxbridge Road.
Campaigners said the authorities needed to review safety measures in regards to the “dangerous junctions” and protect “vulnerable road users” from harm.
In the past five years, two pedestrians and two cyclists have been killed in Uxbridge Road in Ealing, while 46 people have been seriously injured.
A petition - Make Ealing's Uxbridge Road Safe for All - has been launched in the hope the authorities will invest in safety improvements particularly at dangerous junctions and crossings.
It is available to sign until Monday November 27.
The protest comes two weeks after Ms Manera was involved in a fatal collision with a lorry while cycling along the busy road.
In a statement, Terry Patterson, chair of London Cycling Campaign (LCC), said: "We are here to mourn the loss of a member of our community, and to call for change - and action.
"Only a few days ago, Claudia Manera died here in Ealing. She was riding her bike on Uxbridge Road.
"It is a terrible thing to lose someone in this way - a brutal and appallingly abrupt end to a life - and I want to pass on my heartfelt condolences to Claudia’s family, friends and colleagues."
Ms Patterson added: "Everyone who cycles cannot help but be affected by this tragedy, and we must now be looking with even greater concern at the absence of protected space on our roads.
"Yet again a cyclist is involved in a fatal collision with a lorry. Yet again calls by campaigners to make that collision site safe for active travel have been ignored or sidelined.
"Too many times we have been asked to speak at similar vigils across London over the years, when warning signs have been obvious and councils alerted to the danger - but no action has been taken.
"Today we call afresh for Ealing Council to renew their commitment to active travel, and work with TfL to make this junction and this road safe for vulnerable road users."
