The traffic noise in the vicinity of the traffic calming measures

The aim of the study is to analyse and compare the vehicle noise level when driving through the speed bumps and near them.

The traffic noise was recorded in one seconds time interval using a manual sound meter. At the same time traffic movement characteristics were being controlled. The vehicle type, driving techniques and the running speed influence elimination allowed to assess the impact of the traffic calming barriers presence and their slowing effect on registered noise values.
