Containment and baseline noise measurements

By April 16, 2020 No Comments

With partial containment, traffic is halved in Geneva. This represents a unique opportunity to take baseline noise measurements with a view to improving urban policies.

Covid19 has significantly diminished urban activity. One obvious indicator is the reduction in traffic and related noise. Below, we present graphs about traffic in Geneva for a normal work week and a “confined” week; that is, before and during the partial containment ordered in Switzerland.  Traffic has nearly halved on rue du Jura, near the Geneva Institute of Applied Sciences (HEPIA.) HEPIA hosts an intelligent acoustic sensor developed by Securaxis. It tracks and qualifies passing traffic from the sound made through the coupling of acoustics and artificial intelligence.

13’783 vehicles between Mo. 3/02 5am and Fr. 7/02 21pm 
7178 vehicles between Mo. 06/04 5am and Fr. 10/04 21pm

We are looking at a once-in-a-lifetime opportunity to study a city in such specific and quiet circumstances. We can gather the sound-related baseline data for policy-making as we move forward form here and maybe “back to normal”. This data can be used as benchmarks for the development of future noise policies. 

Securaxis’ smart acoustic sensors allow city authorities uninterrupted and real-time monitoring of the return of urban activities. Where will the process start? Which geographical spaces will be first “ reoccupied ” and how quickly? Such data would be of crucial importance after this period of containment for cities wishing to introduce urban changes in favor of the well-being of citizens, particularly in terms of traffic, noise and pollution.
