Some things cannot be planned.
But good transportation routes can.

Rapid progress, safe arrival

We are there to help people who are on the move and need reliable services. 

We offer our customers advice and support in the development and implementation of large- and small-scale infrastructure projects, at local, regional, national and international level, for public and private transport facilities as well as water, gas and electricity utilities.


Efficient traffic systems

Strategic planning (fitness-for-purpose assessments, network strategies, integrated transport strategies), General project proposals/concept designs for road and rail infrastructure, Public transportation operations planning, Non-motorized traffic planning / road safety for schoolchildren, Road safety audit (RSA) / Road safety inspection (RSI), Macroscopic transport models (VISUM/TransCAD), Expert reports on transport issues, Operational mobility management concepts, Parking space planning and technical feasibility, Traffic data surveys, Traffic engineering investigations, Microscopic transport models (VISSIM), Client support / technical supervision for competitions, scenario testing etc.

Efficient transport is key to an attractive, well-functioning living and business environment.  Traffic systems must be designed to meet all relevant economic, ecological and social requirements.

The various activities of our traffic planners are closely geared to the three core transport priorities: traffic avoidance, traffic shifting and low-impact design. At a conceptual and strategic level, we investigate the spatial, technical and economic utility of traffic infrastructure for all transport modes and users. We recommend optimizations to existing transport facilities plus associated control systems and develop mobility concepts. Our neutral, objective and technically oriented approach to traffic planning enables us to advise cantonal departments, municipalities, private enterprises and developers alike.
