We have given careful consideration to the contributions submitted to the City of Lausanne’s suggestion box regarding the subject mentioned in the title, which were forwarded to us as matters within our jurisdiction.

First, it is worth noting that no significant increase in traffic volume was observed between 2010 and 2019 on Route du Jorat, despite the fact that Route de Berne remained open during its redevelopment. This project does not require any additional measures at this time, as the route via Chemin du Pont-Rouge is not a viable alternative in the event of potential traffic congestion on the Route de Berne. The route comprising the Route de Marin, Route de la Claie-aux-Moines, and Route de Vers-chez-les-Blanc, meanwhile, serves as an occasional diversion during construction on the A9, which is currently the case between Vennes and Chexbres (The Federal Roads Office (OFROU), as the manager of the highway network, may at any time, as needed, divert traffic onto municipal or cantonal roads, which can sometimes result in increased traffic on that route).

Finally, as discussed during the information and discussion session on July 14, 2021, with the SDLJ (Lausanne-Jorat Development Company), it is indeed the City’s intention to limit through traffic and expand traffic-calmed zones, not only in urban areas but also in outlying districts. A public meeting may be held to present the overall vision, as well as concrete proposals for your area once they have been finalized.

We hope this information has been helpful and apologize for the delay in our response. Sincerely,

The Department of Mobility and Public Space Planning
