Data show that the Cordula Passage, a large underpass in the center of Baden, is not being used as originally intended, with most pedestrians regarding it as a mere passageway instead of a convenient place to shop and meet with others. Moreover, many young adults have taken to frequenting the passage as a sheltered space to drink alcohol, resulting in a further undermining of a subjective sense of security. We assessed the utility and security of the passage and provided the city with a list of measures that could be taken to create a more people-friendly atmosphere in the passage.
