Abstract

Early studies of traffic calming surfaces (TCSs) led to the development of rumble areas and strips that were employed by local authorities to alert drivers to hazards ahead and where possible reduce vehicle speeds. Residents reactions were not given high priority in these early trials, and it became clear that there was considerable noise disturbance at some sites. Describes the results of test track measurements of noise and vibration that has led to the identification of potentially suitable designs. It was concluded that a sinusoidal surface (Rippleprint) produces the most desirable effects. Also describes testing, where drivers and riders were recruited to rate the noticeability of a range of traffic calming surfaces (including the Rippleprint surface) using their own vehicles.
