TfL will “discuss local people’s concerns” about safety on the A10 after the sister of a woman killed on the road began a new campaign.

Asked by the Enfield Dispatch to respond to the petition recently launched by Gina Sone-Demetrious following the death of her sister Laura in January, TfL’s head of policing and community safety said the incident was a “tragedy” and “should never have happened”.

Laura was out walking her two dogs when she was hit by a car and killed while crossing the A10 at a pedestrian crossing in Edmonton. A 17-year-old was later arrested on suspicion of causing death by dangerous driving and failing to stop – the criminal investigation is continuing.

Ms Sone-Demetrious is now determined to improve safety on the road, which is notorious for speeding and ‘boy racers’, by campaigning for measures such as the installation of additional speed cameras.

Four years ago TfL introduced an average speed camera system on the A10 between Southbury Road and Bullsmoor Lane, and evidence collected since suggests this has led to a reduction of serious injuries. However, the section of the road where Laura was killed still does not have cameras.

Mandy McGregor, TfL’s head of policing and community safety, said: “We take everyone’s safety on London’s roads seriously. Safety is our number one priority and it is our mission to eliminate death and serious injury from London’s roads. Laura’s death was a tragedy and should never have happened, and our thoughts are with her family and loved ones.

“We continue to work closely with Enfield Council and the Met Police to reduce all forms of road danger in Enfield, including on the A10. We are planning to meet with local representatives from the council in the coming weeks to discuss local people’s concerns about road danger here.”
