Lecture: Can attitude towards greenery mitigate road traffic noise perception? A case study of a highly-noise exposed cycling path
Author(s): Aletta Francesco, Van Renterghem Timothy, Botteldooren Dick
Summary:
This study was based on an on-site survey along a highly noise exposed cycling path immersed in the green, in close proximity of Antwerp Ring Road in Belgium. The survey was held at 181 passers-by during a working week in September 2017. The survey included questions about overall cycling/walking experience, perceived loudness of road traffic noise, soundscape appreciation, perceived dominance of sound sources, and overall attitude towards greenery’s potential to reduce noise and improve air quality. A k-means cluster analysis was performed on the scores of the attitude towards greenery (ATC) questions to create an ATC variable reflecting two profiles of users: “positive” and “sceptical” towards greenery’s potential. The effect of ATC on overall cycling/walking experience, perceived loudness of road traffic noise, soundscape appreciation and perceived dominance of sound sources was tested through a set of independent samples t-tests. Results show statistically significant differences between the positive and the sceptical group for the dimensions of annoyance and calmness, perceived loudness of road traffic noise and perceived dominance of road traffic sounds and natural sounds. However, no difference was observed for the two groups in terms of overall cycling/walking experience, suggesting that, for the investigated case, other factors might be playing a role.
