Resident Simon Roberts, of Cavendish Meads, submitted a 223-strong petition after he noticed motorists frequently travelling along Bagshot Road at what he considered dangerously high speeds.
After feeling his concerns were not being taken seriously by Sunninghill and Ascot Parish Council, he submitted the petition to a full Royal Borough council meeting in December.
After results of speed tests along a 30mph stretch of the road revealed the average motorists was travelling six miles per hour over the limit, the council agreed to act.
It installed a pinch point and speed cushion on the road opposite the junction with Fox Covert Close on Sunday. Additional signage has also been placed along the road to remind drivers of the speed limit.
Mr Roberts praised the village’s residents for coming together and making it a safer place for both pedestrians and motorists.
He said: “There was a lot of support for this to happen and it has showed. I have driven through it and it already seems to be working well.
“I think there will always be people who try and push the limits but I think this will make the road safer, especially for the elderly and children.
“The council kept their promises and put the speed cushion and pinch point in in good time. I am really grateful to everyone for their support and help in making this happen.
“I also want to thank Cllr Peter Comber for all of his hard work. This will make a real difference to the community.”
The council is also considering installing traffic-calming measures in Kings Road and Rise Road after Sunninghill resident Louise Bollands also submitted a 271-strong petition in December.
The council is carrying out speed tests with a view to installing traffic-calming measures along the road.
