We have various lines of R&D&I exploring new solutions to overcome the mobility challenges of today and tomorrow, especially in cities, where the negative effects caused by this sector are more serious.

Our solutions are transferred to society through the support and guidance we offer public administrations when developing their sustainable mobility plans on a local or regional level, as well as helping them to access funding and overcoming the technical issues involved in implementing them.

These measures address technological, regulatory, social, financial and environmental aspects, which includes supporting the deployment of electric vehicles and charging points, promoting public and shared transport, improving and optimizing transport networks, deploying infrastructures for more sustainable means of transport, and developing formulas to decentralize pedestrian and vehicle traffic flows.

By doing this, we provide support for urban areas ranging from a few thousand inhabitants to very large populations with a mass influx of tourists, such as port cities.

CIRCE is also available to advise companies wishing to implement sustainable mobility plans, either for employees or because they run large fleets of vehicles. Our support allows them to optimize routes and become more efficient, as well as reducing fuel consumption, minimizing their carbon footprint and boosting competitiveness.


  • Vehicle fleet management

We conduct energy audits to diagnose fuel saving potential, design an action plan and carry out the measures needed to deploy it.

  • Sustainable urban mobility and transport systems

We study urban mobility from a social, economic, environmental and energy efficiency perspective in order to optimize transport system efficiency and improve traffic flows, safety and quality of life in cities.
