Problem statement

Parking, both in terms of supply (e.g. public or private parking spaces) and demand (e.g. parking search traffic or mode choice), plays a major role in the transport planning process. However, due to the strong interdependence between the city and the surrounding area, there are usually car-dominated traffic interdependencies that cannot be influenced by urban transport planning alone.    

A transformation aimed at more multimodality or a change in car trips can only be successful in terms of sustainability if it considers regional transport options. Although a large proportion of people live in these regional interdependencies, i.e. in the surrounding areas of larger cities or regional poles, these journeys have not yet been given sufficient consideration in research.

Objective

The aim is to formulate a sustainable and future-proof vision for the Karlsruhe region. Transformation paths are being developed and tested, which are aimed at a more climate-friendly handling of origin and destination traffic between the city of Karlsruhe and the surrounding municipalities. Particular attention is paid to the analysis and modeling of parking behavior. In the spirit of real-world laboratory research, transfer knowledge is to be generated between the experimental areas and, in particular, the municipal stakeholders.

Methods

The research project uses empirical social research methods, context-specific real-life experiments and various simulation tools. Among others, the agent-based travel demand model mobiTopp (IfV) depicts the influence of parking space management on individual mobility behavior. The research project also incorporates findings from expert interviews, dialog events, a population survey and real-life experiments.
