This study applies non-parametric DID estimators facilitated by machine learning (ML) models for causal inference in a variety of data scenarios. Semi-parametric and doubly robust estimators are established and integrated with the ML-based cross-fitting pipeline. Simulation studies and empirical case studies are conducted to showcase the ability of ML-based DID to detect causal effects from both simulated and real-world datasets. Results suggest that the proposed methods outperform conventional DID models in all data scenarios. Light working models are generally preferred over hyperparameter-dependent ones for their comparable performance, lower computational burden, and higher levels of compatibility to real-world empirical analysis. Empirical case studies also demonstrate how the proposed DID method could be applied to evaluate the impacts of various interventions on travel behaviour in different contexts. The present study adds to the existing travel behaviour literature by leveraging machine learning algorithms and non-parametric estimators to the impact evaluation of external interventions on travel characteristics and expanding the application of causal inference approaches in transportation research.</p></div>","PeriodicalId":51534,"journal":{"name":"Travel Behaviour and Society","volume":"37 ","pages":"Article 100852"},"PeriodicalIF":5.1,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141594587","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}

However, the impact of national culture on shaping CCB in this industry remains unclear. Using three theoretical lenses, namely expectation confirmation theory (ECT), social exchange theory (SET), and cultural dimensions theory (CDT), this study aims to investigate how national culture affects the formation of CCB through the proposed conceptual model. To achieve this, the study gathered responses from 743 passengers—both Turkish (n = 323) and British (n = 420)—using a structured web-based questionnaire. The analysis employed partial least squares structural equation modeling (PLS-SEM) and multigroup analysis (MGA). The results indicated that factors like service quality and value for money have a positive influence on customer satisfaction. Customer satisfaction has a positive impact on behaviors such as giving feedback, advocating for the company, assisting others, and being patient with disruptions.

We address this research gap by investigating the impact of bike-sharing and ride-hailing on metro ridership, using a comprehensive dataset collected in Shenzhen. We also conduct a comparative analysis of these two shared mobility modes based on temporal and spatial dimensions and proximity to job centers. Our results are as follows. 1) Metro-integrated bike-sharing trips are most highly concentrated in commuting hours, primarily near downtown stations, and in areas with easy access to the metro system, while metro-integrated ride-hailing trips demonstrate a more even distribution between morning and evening and are more closely associated with job centers, especially those with inadequate metro service coverage. 2) Compared with bike-sharing, ride-hailing is a more effective shared mobility mode for addressing the “first- and last-mile” issue at night and at stations located far from job centers, but bike-sharing is more complementary to the metro system during peak hours and near downtown stations. 3) The complementary effects of shared mobility are only identified within a certain range. Once the number of shared mobility arrivals exceeds a certain threshold, the effects of bike-sharing become limited and those of ride-hailing shift toward negative.

However, SESS is attributed to low utilization rates in some cities. In this context, the significance of users’ satisfaction with the provided services, along with their loyalty, becomes particularly pronounced. Therefore, it is essential to evaluate the service quality (SQ) from the users’ perspective and understand its effect on satisfaction and loyalty, which are critical factors for the long-term durability and success of service. Thus, this study examines the determinants of user satisfaction and loyalty toward SESS. For this, we conducted an online survey among the SESS users in Chicago. We analyzed the responses using partial least squares structural equation modeling (PLS-SEM) and reflexive thematic analysis (TA). Our results confirm the quality-value-satisfaction-loyalty paradigm and indicate that users’ perceptions of SQ, including safety and security, service availability, interface, and perceived affordability, significantly contribute to user loyalty enhancement toward SESS. Perceived value (hedonic value, utilitarian value, and perceived affordability) and satisfaction mediate the impact of SQ on loyalty. Additionally, the results indicate that those who perceive SESS as cost-effective report higher satisfaction levels. Furthermore, users who have pro-environmental attitudes and view SESS as environmentally friendly are more likely to derive hedonic value from the service and exhibit higher loyalty. The TA uncovers key challenges from the user perspective, including pricing, service timing, end-trip facilities (e.g., parking), street pavement condition, vendor operational zoning, and fleet quality, with a specific emphasis on GPS accuracy. These findings provide valuable insights into user behavioral mechanisms, which can be considered as a manifest for service improvement and enhancing efficiency.</p></div>","PeriodicalId":51534,"journal":{"name":"Travel Behaviour and Society","volume":"37 ","pages":"Article 100856"},"PeriodicalIF":5.1,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2214367X24001194/pdfft?md5=03e14bb1f61346c6417ced7fa9186fa4&pid=1-s2.0-S2214367X24001194-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141481309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thirty-two adult members of Boston’s Blue Bikes bike share wore a GPS unit for up to 7 days. GPS points were used to create buffered track, minimum convex hull (MCH), and standard deviational ellipse (SDE) activity spaces. Multilevel logistic regression was used to estimate associations between docking station density, overall bicycle network density, shared-use trail density, intersection density, land use mix, and greenness, with bike share use. Bike share station density within SDE activity spaces showed a significant positive association with bike share (odds ratio (OR) = 1.19; 95 % confidence interval (CI): 1.02, 1.39).
