The region of South Holland currently has problems with too much car traffic. This not only leads to daily traffic jams, but also creates unhealty cities and unsafe situations on the road. In South Holland, only 26% of the inhabitants get enough exercise on a daily basis. The objective of this project is to create healtier and safer cities by promoting bike usage. This is done through a 2-layer zonation system for the city. In the inner city, no cars will be allowed anymore. In the other parts of the city, the bike network will be strengthened. Also, the network of public transportation shoud be improved to reduce car traffic. The region has relatively good public transportation but still lacks rail connections in some parts, mainly in the south of the region. Mobility hubs that offer bikes can help in switching between modalities. Fast bike routes (‘snelfiets’ routes) will connect people to their work from these mobility hubs, while recreational bike routes will help people experience their local surroundings in their free time.
