Pressure has mounted on Transport for London (TfL) to review road safety measures after three children were involved in a crash in Cheam.

They had been in a Vauxhall Zafira with their mum during a crash with a van in Lumley Road, at the junction with A217, at around 5.30pm on August 22.

But this is the second time the transport authority has been urged to take action by resident Poonam Patel after she voiced frustrations earlier this year.

She said: "I was on my way home from work, but I saw all the commotion with all the cars slowing down.

"I went over, saw the lady, and she was crying. Luckily someone was already helping her, so that was a good thing.

"The children were really upset and shaken. They were sitting on the grass, and they were really well behaved because obviously they were scared as well seeing their mum cry."

A Met Police spokeswoman said officers were called shortly after 5.45pm and the caller was advised to exchange details with the other party involved "as is standard practice".

Ms Patel, 28, claims another accident could have happened moments later as motorists are “impatient” when crossing the dual carriageway into different lanes.

She wants TfL to take further action in reassessing road safety measures on the A217 in a bid to prevent further accidents from occurring.

Penny Rees, head of network sponsorship at TfL, said: “We are looking into concerns raised by residents about the A217 in Sutton, and are exploring safety improvements to the area. Surveys have been completed, and we are reviewing the findings and developing a proposal for discussion with local residents.

"We constantly review our road network to ensure it remains as safe as possible, in line with our Vision Zero commitment to eliminate death and serious injury on London’s roads.”

But Ms Patel is unhappy with the transport authority's response, especially as she fears the safety of schoolchildren is at risk.

She added: "There are children who are starting school soon, when is this all going to happen? They're saying it's going to happen soon, they're implementing things, but I haven't heard anything. They haven't come to residents personally to speak to them, they haven't put anything through our doors - nothing.

"We're just left in the dark, we don't know what's going on, and it's just disappointing really.

"We want something concrete, we want something done now. It's an immediate danger for children."

Sutton Guardian first reported the ongoing concerns in May when a driver was taken to hospital following a car crash in the same area.

Emergency services were called to the incident at around 7.30am on May 17 that day, while the unidentified motorist suffered “non life-threatening injuries”.

A TfL spokeswoman said any physical changes to a road network must be through a public consultation, and residents will be made aware of this before being encouraged to give feedback.
