Abstract
Speed control humps designed at TRRL have had a one year trial on a public road, Cuddesdon way, Cowley, oxford, the first of a small number of sites where trials are being undertaken. Details are given of the method of construction, public reaction and effects on traffic, pedestrians and accidents. The speed control humps on this road appeared to be effective in reducing vehicle speed and traffic flow and to be beneficial to safety. They were acceptable to the majority of residents and drivers. There is evidence that a proportion of the traffic diverted from Cuddesdon way used alternative routes through the estate but this did not appear to lead to an increase in accidents on those routes .(Author/publisher)
