In an attempt to mitigate noise levels, the City of Geneva, Switzerland tested a reduction of the speed limit on two of the busiest roads in the city centre – Boulevard du Pont d’Arve and Boulevard de la Tour.
Sabra, the Office in charge of air, noise and non-ionizing radiation, mandated Securaxis to evaluate the impact of the trial measure in terms of noise pollution. Between July and September 2020 Securaxis deployed a measurement campaign to estimate traffic volume, decibels (dBs) and speed in real-time.
The project allowed to establish a direct link between reduced speed limits and improved noise levels.
It also gave a clearer picture of traffic flow, its composition and the effectiveness of speed reduction measures implemented in central Geneva.
Furthermore, the data and key findings of the project could present with tested remediation measures and their effect as part of a city-wide strategy to mitigate noise pollution.
