Digitalising Road Management: Glarus Leads the Way

Digitalising Road Management: Glarus Leads the Way

Many municipalities lack reliable data on the condition of their road networks. The municipality of Glarus is changing that. Since March 2025, it has been using vialytics – a system that automatically assesses road conditions using a smartphone camera and artificial intelligence. As the exclusive Swiss partner of vialytics, Grolimund + Partner AG supported the municipality in implementing the technology and laid the foundation for modern, data-driven road management.

Grolimund + Partner creates added value in all areas of its offering.

We are leaders in our specialist areas of outdoor noise, road surface acoustics, building physics, software and research & development. We provide high-quality services and develop solutions that benefit people and the environment.

One year of communicating values

One year of communicating values

In January 2024, as "The New Boss", I explained in a video statement what is important to us and to me at G+P. After almost a year as the new CEO, it's time for a little look back. Our values take centre stage. Values are a key success factor, especially for SMEs like us.

«I have been at G+P for just over a year as a project leader in research and development. I have learned a lot about road acoustics and their measurement in the past year, as G+P is a pioneer in this field in Switzerland. At the same time, there is always room to bring my skills and experience to the table, while developing new ones.»

«Noise pollution reduces the quality of life of those who suffer from it. My goal is to reduce them as much as possible – G+P provides me with the means to do this. Street noise and shooting noise - I have been able to develop in these areas thanks to the skills acquired in a dynamic, friendly and stimulating working environment.»

«Working at G+P means working with diverse teams made up of people from different backgrounds, which provides the opportunity to explore new perspectives and approaches. The willingness to learn something new is always present and contributes to increased motivation. The activities at G+P are very diverse and often lead to interesting collaborations, sometimes reflecting personal passions. Self-organisation is a key element that offers great freedom and enables a good work-life balance. We are always on the lookout for new energy solutions, both in the area of sustainability and in the other activities we are involved in. The variety of projects is exciting and ranges from small detached houses to large buildings, often located in protected zones. We work on projects all over Switzerland, sometimes switching from German to French to Italian in the blink of an eye. In short, working at G+P means never being bored!»
