However, this diversity also poses a challenge to educators in terms of effectively training and evaluating these students. This study focuses on a maritime taught postgraduate professional program and investigates how student background characteristics affect their learning outcomes and academic performance. By utilizing both stated preference data (SP) and revealed preference data (RP) collected from a postgraduate maritime professional program in Hong Kong, the study aims to mitigate hypothetical bias and gain a comprehensive understanding of the factors influencing student perceptions and experiences in maritime industry. The study measures five dimensions of student learning outcomes, including professionalism, strategic thinking, lifelong learning capability, career development, and academic performance. The findings suggest that student background characteristics have minimal impact on maritime learning outcomes, with only gender and undergraduate programs showing some influence. The study highlights the inclusive nature of maritime professional education, emphasizing that training quality, rather than personal background, is the key determinant of success.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"159 ","pages":"Pages 392-404"},"PeriodicalIF":6.3,"publicationDate":"2024-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142552452","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}

Focusing on the decade from 2010 to 2019, we investigated how business models, mergers, and upgauging influence these inefficiencies. Our results reveal that 21.2% of the overall technical inefficiency can be accounted for by persistent inefficiency. Despite the U.S. airline industry improving transient inefficiency during the sample period, prevailing persistent inefficiency hindered any significant rise in overall efficiency. The research shows that full-service airlines (FSA) and low-cost carriers (LCC) often exhibit higher persistent and transient efficiency than ultra-low-cost carriers (ULCC). However, there seem to be no significant differences in transient and persistent inefficiency between FSA and LCC. Additionally, the results suggest that the upgauging and higher ramp-to-ramp hours may lead to higher transient efficiency.

Current research on logistics infrastructure safety constructed assessment models without accounting for the catastrophe property of accidents. This research aims at developing an innovative methodology for assessing the safety of logistics infrastructure, which will consider catastrophe property of accident and providing early warning signals for managers and designers. The concept of Logistics Infrastructure Safety Carrying Capacity (LISC) is explored based on the perspective of carrying capacity. The carrier-load model is used to define logistics infrastructure safety. The evaluation of LISC performance employs the Catastrophe Progression Method (CPM) to determine the safety state of logistics infrastructure. By applying the LISC-CPM model to the empirical study of China's logistics infrastructure safety from 2011 to 2022, some conclusions are drawn: (1) The LISC-CPM method is suitable for logistics infrastructure safety monitoring. This model can combine the characteristics of different transportation modes and the catastrophe attributes of safety accidents for early safety warning; (2) Over a 12-year period, the early warning level for logistics infrastructure in China significantly improved, transitioning from “severe-level unsafe warning” to “safe.” (3) There is considerable variation in safety performance across different types of logistics infrastructure. The safety of railway and waterway has the most significant influence on the safety of logistics infrastructure. In general, the study can provide valuable tools for enhancing the safety of logistics infrastructure.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"159 ","pages":"Pages 178-189"},"PeriodicalIF":6.3,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142445534","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 potential impacts of these “robotaxi” services hinge upon not only whether AV technology becomes sufficiently performant, but also whether AV services become economically competitive. In this study, we develop ground-up cost models for a traditional taxi and a robotaxi service to compare their relative competitiveness. We draw on direct observations of commercially available robotaxi services, semi-structured interviews with AV operational and regulatory experts (N = 27), and archival documents to include the most detailed accounting of frontline robotaxi labor roles to date. We find that labor remains a significant cost for existing robotaxi services but that robotaxi operating costs are still lower than those of traditional taxi services. Ultimately, utilization rates and annual mileage will serve as the most influential factors for robotaxi competitiveness. Finally, if jobs shift from traditional taxi to robotaxi services, the total number of frontline jobs could decrease by between 57% to 76%, but the distribution of worker wages would shift higher. Transportation planners, researchers, and policymakers should continue accounting for labor costs in an AV future, as these costs will influence where AV deployment and job losses are (and are not) likely to occur, and should proactively investigate alternative career paths for potentially displaced frontline workers. Robotaxi costs are highly sensitive to lower labor ratios (i.e., fewer vehicles per worker), but firms reach economies of scale relatively quickly. Robotaxi firms should weigh marginal labor cost reductions against impacts to passengers and workers.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"159 ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2024-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142418781","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}

In the model, we highlight the impact of MRO (Maintenance, Repair, Overhaul) costs with economies of scale on airline engine option decisions as well.

The pre-haul parcel pickup and end-haul delivery services within the city are performed by crowd-couriers, thus achieving door-to-door transportation. A mathematical model is developed to jointly optimize the freight allocation problem in the rail segment and the crowd-courier routing problem in the road segment. The freight allocation problem is formulated based on the concept of transportation plans. The transportation plans with and without transshipments are found by a depth-first search-based algorithm in the rail segment. A customized heuristic algorithm based on the adaptive large neighborhood search with multiple operators is designed to find a near-optimal solution.

Recently, many countries have been advocating for autonomous ferries due to their eco-friendliness and potential to mitigate accidents that often occur on traditional manned ferries due to human error. However, the public’s acceptance of autonomous transport systems is frequently influenced by scientific evidence that supports their practical applications. This study endeavours to scrutinise the social acceptance of autonomous ferries from the passenger's perspective, employing the perceived value theory. A total of 151 responses have been collated from our questionnaire, aiming to investigate the public's acceptance of autonomous ferries, and to obtain the users' opinions on key influential dimensions such as the perceived price, quality, value, risk, and willingness to use an autonomous ferry. Structural equation modelling (SEM) has been employed to examine the relationship among these dimensions. The findings reveal that the perceived price and quality have a positive effect on the perceived value, which, in turn, has an indirect effect on the willingness to use autonomous ferries. The conjecture that the perceived risk influences the perceived value and willingness to use autonomous ferries is fully supported by our findings. Building on the findings of this research, this study offers specific recommendations to industry operators and government authorities to guide policy formulation and operational decision-making in the development of autonomous ferry.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"159 ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2024-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142418779","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}
