Conservative councillors David Taylor and Keith Prince, who also represents Havering and Redbridge on the Greater London Assembly, say measures are needed to improve Mawney Road.
There is no crossing on the busy road and instead pedestrians are forced to “perch” on an island between the lanes, they say.
Cllr Taylor said: “I have been contacted by residents, reporting near misses, on a number of occasions. Crossing Mawney Road, close to the A12, just isn’t safe.
“Vehicles travelling on the A12 are moving fast, and regular speeding of 50mph on Mawney Road suggests that they continue driving that way after turning off.”

In a statement, TfL said it was “looking carefully” into the issues raised but was “currently prioritising other locations” due to its “limited resources”.
Havering Council identified Mawney Road as suitable for safety improvements, following a traffic study which identified cars regularly travelling at 50mph.
The road contains a school and large trees can often obscure drivers’ view of pedestrians, councillors say.
Transport for London (TfL) data reports a crash every two months. In a 36-month period up to June 2021, 18 collisions were reported.
None have involved pedestrians, but the Tories fear it is only a matter of time.
Cllr Taylor said: “We shouldn’t wait until one does involve a pedestrian in order to make things safer.
“I will continue to press TfL to make this junction safe, before someone is hurt.”
Cllr Prince claimed the transport body, which oversees public transport in the capital, was “gaslighting” people by “claiming public safety was at the top of its agenda”.
He added: “Leaving junctions like this unsafe is irresponsible.”
The TfL spokesperson said: “Reducing danger on roads across the capital is a vital part of our Vision Zero commitment to eliminate death and serious injury on the network.
“Across the capital, we use a data-led approach to reducing danger and targeting investment in safety improvement projects.
“Given limited resources, we are currently prioritising other locations in London, which have higher collision rates.
“We are however looking carefully into the issues raised and will work with the borough and local communities to discuss any concerns.”
