Abstract:

The objective of this study was to assess cyclists’ exposure to noise in a medium-sized Brazilian city. Mobile sensors were used to conduct the noise measurements in streets with and without dedicated cycling infrastructures. The method can be summarized in the following procedures: i) characterization of the study area; ii) data collection and validation; iii) calculation of exposure indicators; and iv) comparison and representation of the results on maps. Two strategies were adopted for the analysis: spatial data aggregation and temporal data aggregation. As a consequence, the measurements were initially organized in 1,200 nodes distributed along the paths. The results indicate that bicycle riders in São Carlos may be exposed, in some routes, to a high proportion of segments with high noise levels. In the two routes ed for this study, the cyclist was exposed to noise levels above the adopted threshold (> 75dBA) in 33.2% and 18.9% of the nodes. In addition, the possibility of simultaneously working with two related indicators has clearly expanded the classification criteria of the route segments regarding noise exposure.
