Decision making in the urban environment is typically performed using a scenario-based analysis. Stakeholders define a base scenario, which serves as the current situation in a city. Additionally, a reference scenario in which e.g. a road is closed can be defined to study the effects of the closure and make a comparison with the base scenario.
For a scenario-based analysis in a city it is required that multiple domains are covered, such as traffic, air quality, noise and energy. This enables a multi-disciplinary analysis in which the effects of interventions in one domain (e.g. traffic) on another domain (e.g. power consumption for charging) can be studied. A scenario-based analysis could also be performed in multiple domains simultaneously. Additionally, multiple parties could collaborate in one single platform when evaluating spatial plans, such as municipalities, provinces, consultancy companies and housing organizations.
