This paper examines the governance of multimodal integration by combining functionally interrelated transport services into an institutional ‘network-of-networks’ for two case studies in the Netherlands: Groningen-Drenthe and Zeeland. The findings show that central coordination mainly occurs through information and organisation instruments, cliques of actors form around individual transport modes, and the mode of governance depends on network maturity and scope. In this context, barriers of ambiguous responsibility, patchworked policy instruments, and interoperability gaps between transport services affect the network’s ability to achieve positive accessibility and efficiency effects. Future governance designs could balance central coordination to ensure consistent modal availability with decentralised coordination to facilitate bottom-up initiatives. Additionally, implementing instruments that create overlap between mode-specific network cliques may further encourage interoperability.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"21 ","pages":"Article 101525"},"PeriodicalIF":2.4,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144254596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As an emerging service, its implications for ridership and neighborhood improvement of a city are crucial for long-term development. To this end, this paper proposes a framework leveraging standard city data sources to analyze and evaluate the spatial impacts of on-demand transit services for ridership in transit stops and neighborhoods. The utilization of standard data sources enables the framework to be accessible and applicable to vast cities operating on-demand services. A case study of analyses is conducted with real-world data including trips, city census and land use factors at the City of Regina, Canada. We investigated the impacts of on-demand transit accessibility and connectivity, land use and socioeconomic factors on transit stops and neighborhoods. Results indicate that the accessibility and connectivity of the on-demand transit stops positively impact the ridership. It is also found that demand for on-demand transit service is higher for neighborhoods with lower population and income. This indicates the necessity of on-demand transit services for the disadvantaged population. The proposed methods and data sources in this study can serve as a transferable framework for vast on-demand service evaluations. Moreover, the findings of this study also highlight the positive impact of on-demand transit services in shaping transit ridership and neighborhood public transportation.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"21 ","pages":"Article 101512"},"PeriodicalIF":2.4,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144548701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study addresses this gap by conducting an ex-durante analysis of the OV-fiets program in the Netherlands, a station-based round-trip bike-sharing system designed to improve last-mile connectivity for train commuters. The analysis reveals that in the average (balanced) scenario, the net present value (NPV) of the OV-fiets scheme is positive, with a benefit-cost ratio (BCR) of 1.5. This indicates that the scheme has benefited the Dutch society over the 20-year period (2004–2023). In the pessimistic scenario, the NPV remains slightly positive with a BCR of 1.1. This implies that even under the least favourable conditions, where high costs and low benefits are assumed, the scheme still slightly exceeds the break-even point. Conversely, in the optimistic scenario, the BCR rises significantly to 2.4. Primary benefits include enhanced accessibility, reduced road congestion, and improved health outcomes. This research underscores the considerable societal value of the OV-fiets program in the Netherlands, warranting continued investment in the program and emphasising the need for ongoing bicycle safety measures and infrastructure improvements. However, OV-fiets might be successful in the Netherlands; our analysis also shows that copying it into other contexts is not straightforward.
