Calm Streets has a role in working with young people who hang around the Metro system and stations. At the stations, there are groups of young people who patrol the network in pairs. They are there to assist passengers and enhance their feelings of safety, but not to apprehend troublemakers. They talk to young people, gain their trust and attempt to engage them in constructive activities. Such interventions are said to prevent offending behavior in the wider community, including on the Metro system. The ethos of Calm Streets is to recruit people who are representative of the young people they work with. That is to employ people with similar life experiences and ethnicity and live in the same geographical areas in Stockholm County. There is a great deal of frustration among young people, especially those who come from immigrant communities, because those working for the police and other official organisations do not reflect the diversity of Stockholm's present day residents. Calm Streets wanted to break this pattern and give those socially excluded young people an opportunity to access employment and act as positive role models to other young people from economically disadvantaged communities.
