As part of the EU research project SILENCE an extensive literature study of the noise and annoyance effects of various road traffic flow measures has been carried out. For traffic calming as a whole, noise reduction potentials of up to 4 dB LAeq and 7 dB LAmax has been found. The effect on noise as well as on annoyance is highly dependent on traffic composition and speed, road layout and the use of individual measures such as road humps, chicanes, gateways, and mini-roundabouts. Other measures included in the study are rumble devices, junction layout, speed reductions using static and variable speed signs, automatic traffic control, congestion charging, parking information systems, city logistics and nighttime ban on trucks. Most of the measures need further studies if firm conclusions are to be drawn regarding the noise and annoyance effects; only humps and speed cushions have been studied extensively regarding noise and annoyance.
