Abstract
The objectives of the study were to investigate the effect interrupted traffic flow has on traffic noise and to determine an applicable adjustment factor. The basic method of analysis consisted of comparing the field data taken at intersections to determine if the measured noise levels changed as a function of distance from the intersection. Results showed that interrupted flow conditions did not cause an increase in the L10 or Leq noise levels. Data taken before and after the installation of traffic signals showed that the addition of traffic signals did not significantly affect the average noise level. A comparison of measured and predicted noise levels showed general agreement.
