To this end it is important to ascertain the role played by psychological factors, along with instrumental attributes, especially among younger adults (future purchasers) in not yet mature markets. Our paper analyses and models the propensity to purchase an EV with respect to an equivalent IC vehicle. It contributes to the existing literature investigating younger adults’ behaviour in an emerging market, focusing on the role of attitudes and perceptions. A stated preferences survey, built on real commercial scenarios (Renault ZOE vs Renault Clio), was designed and disseminated at the University of Cordoba (Argentina). Respondent behaviour was modelled within the random utility paradigm. First, heterogeneity among users was investigated through mixed multinomial logit formulation; The role of psycho-attitudinal factors was then explored through the specification of hybrid choice models with latent variables. Estimation results indicate the significant role of attitudes and perceptions in emerging markets.KEYWORDS: Hybrid Discrete Choice Modellinglatent variablesattitudesperceptionselectric vehiclesemerging markets AcknowledgementsThis study was carried out within the MOST – Sustainable Mobility National Research Center and received funding from the European Union Next-GenerationEU (PIANO NAZIONALE DI RIPRESA E RESILIENZA (PNRR) – MISSIONE 4 COMPONENTE 2, INVESTIMENTO 1.4 – D.D. 1033 17/06/2022, CN00000023).

Therefore, the estimated monthly cost is €200.2 It is important to recall that we are dealing with students who are undertaking the choice of purchasing an electric vehicle in a not yet infrastructured market.3 The minimum sample size was preliminarily defined in accordance with the literature (Louviere, Hensher, and Swait Citation2000; Hensher, Shore, and Train Citation2005) by using following analytical expression: n≥qpa2[ϕ−1(1+α2)]2where p is the true proportion, q = 1 – p; α is the level of confidence (0.95); a is the accuracy (10%); and is the inverse cumulative normal distribution function.4 Cronbach’s alpha is a conservative measure of reliability.

Several studies have assessed the performance of alternative designs against a range of traffic volumes and geometric design aspects, each in isolation, but a model which can factor in multiple variables into the analysis is the identified research gap. The displaced left-turn – DLT intersection design was found to be the most versatile, efficient, and transferable to locations elsewhere in the world. In this paper, a displaced right-turn intersection – a variant of DLT, was modelled for a range of traffic flows and design conditions. Regression models were developed for Practical Reserve Capacity and Delay as dependent variables with traffic flow, proportion of right-turning traffic, signal cycle time and length of displaced turn as explanatory variables. These models can provide relatively quick preliminary estimates of the performance indicators before committing to resource-consuming junction remodelling works.","PeriodicalId":23345,"journal":{"name":"Transportation Planning and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135483409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The article aims to estimate operational efficiency for CTOs by the Slacks-Based Measures (SBM) model when considering CO2 emissions and work accidents as undesirable outputs. In doing so, this paper adopted the cluster analysis to select homogeneous CTOs acting as Decision-making Units (DMUs). CTOs in the Cai Mep-Thi Vai port (the CMTV case) were then empirically studied to verify the validity of the suggested model. The results could have real-world applications for CTOs looking for managerial actions to boost operational efficiency and maintain high-quality growth. Additionally, the research model may provide an analytical reference for relevant port management applications. In particular, this study offers CTOs a scientific framework for evaluating the operational efficiency of CTOs located in a port.KEYWORDS: Operational efficiencySlacks-Based Measurescontainer terminalswork accidentsair emissionscontainer terminal operators AcknowledgementsThe authors would like to thank colleagues for very thoughtful reviews and critical comments, which have led to significant improvements to the early versions of the manuscript.Disclosure statementNo potential conflict of interest was reported by the author(s).","PeriodicalId":23345,"journal":{"name":"Transportation Planning and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135831096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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 the following: (1) the relationship between built environment and ridership shows different types of curves. (2) The path distance to the metro station and the visual perception of road space have more significant impacts on ridership than road network density.

Most previous work on AVs perceptions is based on large cities or metropolitan areas. This study provides a unique perspective regarding perceptions of impacts of AVs in small and rural communities through an online survey in Central Texas (n = 1153). Our questionnaires gathered basic socio-demographic characteristics and AV impacts variables identified from the literature. We used summary statistics and ordered logistic regression models to reveal the perceived impacts of AVs. Residents of small and rural communities, particularly older adults (65 + years), were more enthusiastic about the development of AVs than the national average. Our findings reveal that being an employed, married male with a higher income increases the likelihood of accepting the impacts of AVs, suggesting further research to explore a feasible approach to utilizing AVs in small, rural communities.KEYWORDS: Autonomous vehiclePerceptionSmall townRural community AcknowledgmentsWe are grateful to Susan Chrysler, Stacey Alejandro, and Elissa Cuellar from Texas A&M Transportation Institute for their strong support during the data collection.Author contributionsThe authors confirm contribution to the paper as follows: study conception and design: M.

We address these questions through the case of Brussels and its long-standing docked BSS ‘Villo!’. Our study analyses comprehensive (consecutive 12 months) and disaggregated (station level) data on rentals and returns and finds that Villo! is used mostly in dense (although not all) districts also well served by PT. However, temporal structures suggest Villo! overtakes PT at night in vibrant districts and possibly in selected districts with lower PT services over weekends. In addition, Villo! stations at key PT hubs usually do not show specific temporal patterns, which suggests intermodality may work at all times during PT operations. There could be an evening peak effect combined with the Brussels’ topography, but this needs to be confirmed by on-site surveys.KEYWORDS: Bike-sharingpublic transportspatiotemporal analysisprincipal component analysis AcknowledgmentMichał Dzięcielski gratefully acknowledge the computational grant from the Supercomputing and Networking Center (PSNC) in Poznań, Poland.Disclosure statementNo potential conflict of interest was reported by the author(s).Notes1 In Brussels, the ‘premetro’ is an underground-like infrastructure operated by tramways that ride both underground and in the streets.2 JCDecaux API, https://developer.jcdecaux.com/#/home (Accessed 22.04.2023).3 The monthly patterns of Villo! ridership could not be investigated because the period of the investigation was disturbed by post-pandemic recovery and thus increasing usage over time.4 Mathematically speaking, for each PC the statistical package computes the linear correlation between the supplementary variable and the scores.5 We argue that the value of a bike is proportionally higher for a poorer household than for a privileged one.6 This amount is not debited but must be available for the case rules would not be respected.","PeriodicalId":23345,"journal":{"name":"Transportation Planning and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135395531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, limited research has been conducted on how the use of e-mopeds, one of the most prevalent transportation modes in China, impacts residents’ SWB. To address this gap, this study utilizes survey data from eight traffic analysis zones in Shanghai to conduct an empirical investigation focused on the relationship between the use of e-mopeds for various purposes and residents’ SWB. A Bayesian network (BN) model is established to explore the correlations among travel-related attributes, socio-demographics, and SWB. The model's results reveal a strong correlation between e-moped usage and the likelihood of achieving higher SWB. Consequently, supporting the development of e-mopeds in Shanghai is considered crucial, and targeted policies are suggested.","PeriodicalId":23345,"journal":{"name":"Transportation Planning and Technology","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86674916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
