My expertise focuses on traffic and transport in relation to the environment, such as air quality, noise and climate change. Sustainable mobility in all its aspects. On one hand my interest focuses on the what and why question in these knowledge fields, and on the other hand I recommend and encourage employees of national - and regional authorities on realizing the traffic and transport measures with the compliance taking the environmental aspects. Through my broad network I unlocks the knowledge from the knowledge institutes if possible For every question there is an answer, a solution.As project leader of different mobility plans - green transport plans (the Meuse, and Ministry the Hague VenW) I have been with the boots in the mud to change the mobility behaviour of our own employees.
