In 2015, Prague designed three possible scenarios and organised a workshop for experts, as well as a sociological survey to select the most suitable scenario. 57 selected experts gathered in groups and discussed the scenarios in a half-day workshop. A sociological survey collected additional opinions from 2,224 citizens. Based on the combined opinion of stakeholders and citizens, Prague developed its final transport strategy. Designing an expert workshop and a sociological survey with essential, easy questions is an easy, cheap and illustrative solution for scenario selection. It also provides a powerful basis vis-à-vis to political approval, as based on broad and balanced experts’ opinions.
