The reference model applies methods including expert interviews, artificial neural networks, and dynamic programming. We present a case study of an international cold-chain logistics company determining the optimal replacement year for refrigerated trucks. Based on scenario analysis, findings show the optimal vehicle replacement year varies depending on operational environments and service requirements. The cold-chain logistics company can use these findings to establish its preventive M&R policy for refrigerated trucks, as well as identify the optimal year for replacement. The proposed reference model can serve as a guideline for cold-chain logistics companies' fleet management.</div></div>","PeriodicalId":47453,"journal":{"name":"Research in Transportation Business and Management","volume":"57 ","pages":"Article 101235"},"PeriodicalIF":4.1,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142656471","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}

The results show that a wide variety of actors can position themselves as CPO and in different charging set-ups, where, for example, logistics service providers (LSPs) could utilize private charging at terminal, while also offer public charging along the road network. Other actors expected to take a role as CPO include shipper, fuel stations, energy companies, and truck manufacturers. In terms of resources, activities, and interaction for CPOs, these coincided to a large extent among actors, such as necessary possession of charging hardware and software, and necessary interaction power grid actors. Furthermore, this study suggests five distinctive roles of CPOs that actors take: gatekeeper, accessory provider, contributor, facilitator, and orchestrator. By focusing on the unexplored role of CPO, this study has important implications for both research and practice.</div></div>","PeriodicalId":47453,"journal":{"name":"Research in Transportation Business and Management","volume":"57 ","pages":"Article 101239"},"PeriodicalIF":4.1,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142656470","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}

Typically, time series forecasts for traffic demand and flow are computed using a global study area, which does not account for spatial heterogeneity. To address this, a periodical decomposition-based two-stage NARX (Nonlinear Auto Regressive with Exogenous Inputs) model is developed to accurately predict free-floating bike-sharing travel demand (BSTD) for individual hotspot areas. Kernel density analysis-based hotspot detection is employed to divide the study area into basic predicting units, thereby enhancing efficiency and guidance quality. Weather factors with poor predictability or low correlation with BSTD are further eliminated using rescaled range and gray correlation methods. Based on periodic decomposition results, an improved two-stage NARX model is constructed for BSTD prediction in multiple important steps. A random selection of 50 hotspot areas in Beijing was performed for methodology verification, with hotspots numbered and selected using a random number generator. Results indicate that the periodical decomposition-based NARX model significantly improves BSTD prediction accuracy in hotspot areas compared to typical time series forecasting methods. The model demonstrates higher R-values (correlation between targets and outputs) and lower MSEs (Mean Squared Errors). For instance, the average MSE of the periodical decomposition-based two-stage NARX model is 20.225, compared to ARIMA (26.151), NARX (28.748), ARIMA (32.854), and NAR (41.666), highlighting superior robustness and effectiveness across different hotspot types and locations. These findings enhance understanding of the spatial-temporal variation of BSTD and provide a foundation for optimizing time series forecasting within specific areas.</div></div>","PeriodicalId":47453,"journal":{"name":"Research in Transportation Business and Management","volume":"57 ","pages":"Article 101237"},"PeriodicalIF":4.1,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142656472","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}

The present study intends to answer these questions by investigating zonal level boardings of bus transit system in the city of Winnipeg, Canada. For this purpose, two multivariate adaptive regression splines (MARS) models were developed: (i) a time-series MARS model based on historical transit demand patterns at zonal level, and (ii) a regressive MARS model to predict demand decline as a function of land use, socio-demographic, and zonal-level variables. The magnitude of the demand decline was found to be highest in April 2020, with a total loss of 1.74 million boardings attributable to the COVID-19 pandemic. Among 840 zones, transit usage in commercial (50 %–60 % reduction), education (80 % reduction), and recreational (60 %–80 % reduction) zones are most affected by pandemic restrictions.

Moreover, continuity was positively associated with projects incorporating AI-driven demand-responsive transport and/or multimodal services as well as those in target areas with formulated local public transportation plans.

A case study was performed, employing a SEM-MIMIC approach to the answers of a questionnaire applied to students, teachers, and support staff of a university in the interior of southern Brazil. Seven constructs affecting satisfaction were identified and the relationships between them were investigated. These were as follows: walking infrastructure, noise, safety, trip to the stop, infrastructure of stops, trip in the vehicle, and service operation. The results revealed that the greatest influence on overall satisfaction was related to the user's experience inside the vehicle and the characteristics of the service. It was also evident that there was a high direct effect of the users' overall satisfaction on their behavior. The study population presented homogeneity, although younger users were less loyal and less likely to recommend the bus to others, while owning a private vehicle improved satisfaction with the operation of the service.</div></div>","PeriodicalId":47453,"journal":{"name":"Research in Transportation Business and Management","volume":"57 ","pages":"Article 101233"},"PeriodicalIF":4.1,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142573198","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}

Drawing on the consumer perceived value theory, we employ app perceived value and bicycle perceived value as mediating variables to construct a model of consumers' behavioral intentions to use bike-sharing. The study finds that app perceived value and bicycle perceived value are strong predictors of consumers' willingness to use bike-sharing. At the same time, app perceived value also indirectly affects their perceived behavioral control of using bike-sharing through the mediating role of bicycle perceived value. Furthermore, the perceived usefulness, ease of use, and security of the app are found to positively impact app perceived value, which in turn increases the preference for bike-sharing of consumers.
