The Wuppertal suspension railway is well known in Germany. To further improve accessibility, the city considered a cable car that would connect the city centre in the valley with a school and the University Campus on the hillside. The idea was to overcome the demanding topography of the city.
The project was controversial, as the cable car would run over inhabited areas. Therefore, the mayor decided to involve citizens in decision making. Using the method of Planning Cells, 50 randomly-selected residents discussed the issue for four days and provided their recommendations in a citizens’ report.
