During the modern period, the strategy of creating safe school routes for children and separating them from cars by building tunnels was a popular solution to eliminate the need for children to cross the street. Tunnel crossings for pedestrians and cyclists act as important linkages between neighbourhoods, but many people do not feel safe using the tunnels. Nowadays, many tunnels are in need of renovation and improving the feeling of safety is a great challenge, because these places lack ‘eyes on the street’.
In the Swedish city of Helsingborg, the municipality came up with the idea of a “Tunnel Tool”, which is a quick and easy way that gives a great effect with little cost. The tunnel tool is a process of renovating unsafe tunnels in collaboration with the local community and artists. In this manual, Moa Sundberg and Cecilia Fredriksson from the Municipality of Helsingborg, who were involved in the project, share their experiences, guidelines and practical tips that may be useful in applying this tool in other cities.
