In correspondence with the council they have indicated that they plan to check the average road speeds before and after the cushions are installed to check whether they are effective in reducing speeds to 20mph.
Low height cushions have been chosen to reduce the impact on vehicles. In addition there will be gaps either side of the cushion so as not to impede cycles.
