I bring together behaviour, data and mobility.

Numbers on their own change nothing. I find out why people travel the way they do, combine that with the information already out there, and present it so clearly that a policymaker can act on it straight away.

DAM: mobility data on one map

A web application where users combine open data with their own sources, then make selections and run statistics on them.

• The road network, traffic signs, collisions, schools and colleges, and more, on one map
• Reports that compile themselves, such as a road safety risk analysis
• Modules for route analysis and for testing against Sustainable Safety, the Dutch road safety approach

From concept to a product in use: design, data connections, servers, users and licences.

  Freight flows between European regions, mapped

  A logistics dashboard that shows where goods come from and where they go, and research into how well the European regional classification (NUTS) works for that purpose. Presented at the closing conference of InnoWaTr in Harlingen, an Interreg North Sea project with 24 European partners.

  What does the vehicle fleet mean for an area?

  A model that estimates the distance travelled, the CO₂ emissions and the electricity demand of every registered vehicle, down to postcode level. It shows policymakers where a cleaner fleet would make the biggest difference.

  Safety culture and traffic incidents

  In-depth interviews within a company about time pressure, phone use at the wheel and fatigue. The aim was to understand not only what happened but why it could happen, and what the organisation itself can change.
