About speed restriction measures
In general, we introduce traffic calming to reduce accidents and their severity within residential areas.
We can also introduce them for environmental reasons, such as reducing "rat-running" problems.
Traffic calming is mostly used in 20mph zones to help make the lower speed limit self-enforcing.
We monitor accident data provided by Greater Manchester Police to highlight where clusters of accidents occur and look to introduce improvements to reduce the accident numbers.
We investigate requests for the introduction of safety schemes, but our priority is dealing with areas where accidents are occurring now.
