Building a better environment for people on the move

Our vision is to improve the walkability, efficiency and safety of the built environment, in railway stations, airports, stadiums, streets, buildings and landscapes. "Better starts now" is our brand statement. The thinking behind it - from the inception of the company more than a decade ago - is that no matter who you are or what you do, it is always possible to make something better - and now is the time to start doing it.

Pedestrian simulation with SimWalk improves the walkability of the built environment in a comprehensive and efficient way for planned or existing facilities and infrastructures. The technology reduces the costs of design bottlenecks and operational inefficiencies, resulting in an environment worth walking.

We strive to provide a state-of-the-art, user-friendly simulation software to empower transport planners, engineers and safety experts to deliver client projects fast and in time. We highly value support services and training for our clients. In addition, we strongly encourage the use of pedestrian simulation in academia and pedestrian research in general.

We succeed if people can walk comfortably and safely in all the built enviroment.
