A mangement strategy reduced truck movements at night on an urban arterial roadway. Community response to noise was measured using a panel of residents, surveyed five times over the two years of the study. Noise monitoring showed no change in Leq or Lnight levels, but the panel did report significant benefits in terms of reductions in noise annoyance and reduction in activity interferences. The conclusion was that measureable changes in the number of articulated truck movements at night lead to reduction in the number of noise events at night and to significant improvements in the community’s road traffic noise response. Relatively small changes in the number of noise events in the road traffic noise stream have an effect on annoyance responses beyond their contribution to the levels of the energy-based indicators
