However, private parking space suppliers hesitate to participate in shared parking programs due to the trade-offs between benefits and risks. Therefore, understanding the motives behind the reluctance of potential suppliers is crucial for incentivizing their participation. This study integrates the technology acceptance model (TAM) and expectation confirmation theory (ECT) to investigate the formation mechanisms of behavioral intentions. A three-step analytical approach is employed, comprising structural equation modeling (SEM), necessary condition analysis (NCA), and fuzzy-set qualitative comparative analysis (fsQCA). SEM is used to validate the causal relationships and net effects among variables within TAM and ECT, while NCA is used to identify the key prerequisites of potential supplier participation. Finally, fsQCA examines how different configurational effects shape behavioral intentions. The SEM findings suggest that although potential suppliers accept shared parking technology, high decision-making costs (e.g., time and maintenance) reduce their satisfaction and willingness to participate. Further multigroup analyses reveal heterogeneous decision-making motivations in which owners are more risk-averse, whereas renters prioritize stable returns. Additionally, NCA and fsQCA reveal that owners’ behavioral intentions are driven by confirmation and perceived availability, while renters’ intentions depend on confirmation, expectation, satisfaction, and social influence. Nevertheless, perceived risk and low availability are the principal obstacles for both groups. By integrating TAM and ECT, this study enriches the theoretical understanding of shared parking and provides practical recommendations for enhancing potential supplier participation.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"174 ","pages":"Article 103861"},"PeriodicalIF":6.3,"publicationDate":"2025-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145333768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using survey data on commuting practices in Oslo, designed to focus on practice connections, we employ logistic regression analysis to identify connections between commuting and other everyday practices. Our findings reveal that commuting practices are positioned within a nexus of coordinated practices embedded in material and spatial-temporal arrangements. Specifically, commuting practices connected with shopping, childcare, and leisure activities foster car dependencies. Material and spatial-temporal arrangements of different work practices foster car dependency for the work commute: those working shift hours, that needed to transport work equipment, and who had work tasks across multiple geographical locations were more dependent on commuting by car. The results suggest that car commuting offers greater scope for negotiating the coordination of connected practices. We discuss the implications of our findings for policy approaches for sustainable mobility, arguing that cross-sectoral policy initiatives focused on the ways in which practice connections are coordinated are necessary.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"174 ","pages":"Article 103855"},"PeriodicalIF":6.3,"publicationDate":"2025-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145333766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To comprehensively understand the impact of SMM on bus ridership while accounting for spatiotemporal heterogeneity and unidirectional time effects, this study employs the Unidirectional Geographically and Temporally Weighted Regression model to analyze the influence of the SMM system—comprising free-floating bikeshare (FFBS), station-based bikeshare (SBBS), and electric free-floating bikeshare (E-FFBS)—on bus ridership in Yancheng, a representative medium-sized city in China. The results suggest that the SMM system is negatively associated with bus ridership overall, with heterogeneity across modes and spatial contexts. FFBS and SBBS exhibit positive associations, particularly in peripheral areas, while E-FFBS shows a negative association in both central and peripheral zones, attenuated in areas with well-developed bus networks such as the southern new urban district. Ridership levels also differ across land-use types, with commercial zones aligned with lower usage, while residential, employment, and educational areas exhibit stronger bus utilization. Demographic segmentation indicates that young adults are generally linked to lower bus usage, except in areas with high-quality services. Weekday–weekend comparisons reveal that the favorable linkages of FFBS and SBBS with bus ridership are less salient on weekends, while the presence of E-FFBS more consistently corresponds to reduced usage, likely due to leisure-oriented travel.

Notably, resilience under specific strategies (node degree and risk probability) was generally lower than that in random node strategies.

However, recent research highlights the networked nature of accessibility impacts. This presents challenges in causal research, particularly in mapping accessibility impacts, defining treatment and control groups, and estimating property price effects. Using the Evergreen Extension in Metro Vancouver, this research examines how proximity to new stations and changes in accessibility over time are capitalized into property prices, disentangling their distinct and combined effects. As commonly applied in the literature, the proximity-based measures identify treated properties based on their distance to the nearest station. For the accessibility-based approach, we measure changes in gravity-based scores over time to capture regional accessibility effects and treatment intensities along an ordered continuum, identifying areas experiencing accessibility gains, losses or stability. Results show that the spatial distribution of accessibility-based effects extend beyond conventionally-defined proximity catchments, suggesting an accessibility-based approach can better capture potential treatment effects associated with network spillovers. Next, fixed-effects models, using repeat sales, are then estimated to causally identify price premiums associated with both the proximity-based and accessibility-based measures. First, we find that, in line with urban economic theory, 1) proximity to new stations is positively valued, 2) increases in network access and regional connectivity to employment yield larger positive price effects, and 3) there is a combined premium placed on both proximity-based and accessibility-based benefits. Second, while proximity effects align with expectations, where treatment properties closer to the new stations command higher price premiums than those farther away, accessibility-based price effects do not. Specifically, higher treatment levels in the accessibility-based models do not consistently yield the highest premiums. This prompts an important perceptual question on whether homebuyers view proximity as a more intuitive signal of accessibility than broader regional network connectivity, which may be more intangible. We contribute knowledge through a dynamic approach that captures accessibility impacts for causal estimations, moving beyond the limitations of proximity-based measures in transit impact research.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"174 ","pages":"Article 103852"},"PeriodicalIF":6.3,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145333769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This national trend questions the effectiveness of investment in SRTS projects. This study conducts a comprehensive review of 55 research articles evaluating the effectiveness of the SRTS program in the United States through a policy effectiveness framework. Three findings are discerned. First, the existing literature focuses predominantly on studying the relationship between SRTS projects and the rate of active travel to school, and less on investigating pedestrian and cyclist injury and risks, as well as the funding allocation of the projects. Second, the number of research studies evaluating the effectiveness of SRTS projects is disproportionately higher in California, Texas, Florida, and New York. Third, despite the valuable insights offered by the existing research literature, it is evident that the overall effectiveness of the SRTS program on a national level falls short of expectations. This might be due to (i) the instability of program support and effectiveness, (ii) the lack of a reliable and sustainable assessment system, (iii) inadequate evaluation of co-benefits, and (iv) the absence of a consistent feedback obligation. Future initiatives and investments are urged to (a) support testing, studies, and evaluations on a local scale before implementation at the national scale, (b) prioritize the development and implementation of a uniform and mandatory evaluation system from the beginning, and (c) implement a mandatory feedback system from project implementors and users.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"174 ","pages":"Article 103846"},"PeriodicalIF":6.3,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145333871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results indicate that all external environment factors (i.e., platform incentives, social influence, and media exposure) positively influence internal psychology factors (i.e., perceived usefulness, perceived greenness, and perceived fairness), which subsequently enhance the public acceptability of MaaS.

To address this topic, two sub-samples have been extracted from a macro-survey conducted in the Region of Madrid: (i) users who have adopted shared micromobility (kick-scooter and bike-sharing) and (ii) users who have adopted <em>shared macromobility</em> (i.e., car- and moped-sharing).
