This study researches how station-based bike-sharing can be implemented in strategic transport models. Implementing station-based bike-sharing is a challenging topic, as it requires to combine two modelling techniques. The first is modelling transport tours to make sure that a person who rents a bike returns the bike to the same station. The second challenge is to model multimodality, because shared-bike are always used in combination with other modes. The most prevalent approach on the market to combine the topics is the two-step mode-choice approach. However, the two-step mode choice approach has three important limitations to model SB-bike-sharing. Therefore a new approach is proposed in this study; “The tour-based mode-chain and station choice approach”. Based on a small-scale theoretical case-study the new method gives promising results regarding modelling the combination of tour-based-mode-choice and multimodality.
