Living Lab Veiligheid is a new instrument for gaining knowledge about urban security. At a number of locations in common areas test environments have been created for experimental measures to improve security and liveability. Researchers can test the effectiveness and refine their methods before they are introduced on a large scale. A test period prevents costly adjustments afterwards and removes unnecessary fears of side effects. It is a project by Twynstra Gudde, TNO, The Hague University of Applied Sciences, the Verwey-Jonker Institute and the Public Security Innovation Centre (PSIC).
