The City is committed to doing everything in its power to reduce the negative effects of road traffic on the health of Lausanne residents and the environment. The impacts of road traffic are well-documented and proven; for this reason, several measures have been developed over the past few years, including the creation of traffic-calming zones and, starting at the end of this year, the implementation of a 30 km/h speed limit at night on most of the city’s main thoroughfares.

The City shares your view on the need to moderate traffic throughout the municipal road network. However, the implementation of speed-moderated zones must comply with applicable laws and regulations and requires the development of projects that include measures to effectively reduce speed. That is why a study is currently underway to define a strategy for deploying speed-reduced zones throughout the city, with the intention of implementing them gradually over the next few years.

Pending the results of the aforementioned study, a significant improvement in terms of reducing traffic-related noise pollution is expected after the summer thanks to the implementation of the “30 km/h at night” speed limit.
