URBAN SPEED LIMITS - A MEASURE OF PROTECTION AGAINST TRAFFIC VIBRATIONS

HASTIGHETSBEGRAENSNING I TAETORT - SKYDDSAATGAERDER MOT TRAFIKVIBRATIONER

The aim of this investigation was to study the effect of reducing the speed limit from 50 kmph to 30 kmph on the vibration levels in adjacent buildings. Also the effects on existing cracks in buildings were studied and measurements of infrasound were carried out. The buildings were classified according to the method of foundation. The following main conclusions were drawn from the study. (1) the frequency of oscillation of the vibrations in cellar walls was reduced by 33% on an average. (2) the amplitude of cracking movements was reduced on an average by 23% for long periodic and by 27% for short periodic vibrations. (3) the equivalent vibration level measured on floor surfaces was reduced by 5,0 vdb on an average. (4) the infrasound level was reduced by 4 db on an average. /TRRL/
