The Kattegat/Skagerrak region is facing environmental, health and transport challenges due to the increasing traffic in the Scandinavian cities. Through the project Nordiske cykelbyer (Nordic cycle cities) Norwegian, Danish and Swedish municipalities participated in the project forming a network of Nordic cycle cities as an environmental friendly and salutary solution to the problem. This concept included a common strategy, a common process plan, continuous exchange of knowledge and experiences as well as common development of methods and benchmarking.
