This ambiguity has resulted in weak oversight, reduced professional accountability, and barriers to effective regulatory reform. The undefined nature of pilot offices raises practical and legal concerns, particularly in areas such as performance supervision, internal governance, and legal liability. This article examines the structural and legal shortcomings of Taiwan’s pilotage governance by analyzing relevant legislation and administrative practices. It also draws comparative insights from five foreign pilotage systems (the United States, Japan, Singapore, the United Kingdom, and China) and three domestic professional associations (attorneys, CPAs, and physicians) to highlight viable institutional models. This research demonstrates the need for a statutory framework that clearly defines the legal identity and responsibilities of pilot offices. The article concludes by offering recommendations for reform that would strengthen institutional legitimacy, improve transparency, and align Taiwan’s pilotage system with contemporary standards in maritime governance.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"23 ","pages":"Article 101713"},"PeriodicalIF":3.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146037382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike prior EAT studies focused on short urban trips, this research analyzed a long-distance corridor in northern Utah, United States, where the substantial travel time savings make it a highly feasible setting for early adoption. Methods combined a revealed preference–stated preference (RP–SP) mixed logit model with observed origin–destination travel data. The first objective assessed mode shifts following the introduction of EAT service for airport trips. Results show EAT could divert approximately one-third of trips from private vehicles and ride-hailing, reducing corridor traffic by over 160 vehicles daily. This shift could reduce airport parking demand and tailpipe emissions, improving air quality. Forecasts also predict a modest decline in public transportation ridership from approximately 6% to 3%, potentially undermining bus service revenue and disproportionately impacting lower-income travelers. The second objective conducted sensitivity analyses to evaluate the robustness of EAT demand to various factors. Findings revealed that in-vehicle travel time, travel cost, service frequency, autonomy, and the number of parking days significantly influenced mode shifts. EAT market share was projected to increase from 17% at a higher EAT travel cost of $4.50/mile (near-term) to 63% at a lower EAT travel cost of $0.50/mile (long-term). Vertiport expansion in the study area showed diminishing returns beyond one site, suggesting locations for priority deployment. These findings support evidence-based planning and equitable implementation of EAT services.</div></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":"23 ","pages":"Article 101716"},"PeriodicalIF":3.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146077308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Next, the willingness to pay (WTP) of the commuters for the MFS is estimated. In addition, the study explores the effect of commuters’ trip-related and socio-economic characteristics on the WTP values. For both these purposes, Random Parameter Logit (RPL) models are developed to estimate the WTP values and also for assessing the effect of their socio-economic status and trip-related characteristics on the WTP values.

We used flight and weather data from 2022 to create a complete dataset by cleaning data, creating new features, and combining information. We tested several models including KNN, Support Vector Machine, Decision Tree, Random Forest, AdaBoost, XGBoost and CatBoost. The results show that ensemble models did the best, with CatBoost and XGBoost reaching 95% accuracy. To make these models more understandable, we used the LIME method, which showed that weather and scheduling were the main factors influencing delays. This study uniquely applies explainable machine learning to predict flight delays in a developing country context, specifically at Hazrat Shahjalal International Airport in Bangladesh. Most previous studies focused on countries like the UK, USA, Saudi Arabia, or China etc. By providing accurate predictions along with clear explanations, the results show how airlines and airport authorities can improve scheduling, better use resources, and meet international delay standards.

This study aims to develop a context-specific framework for outsourcing pilotage and towage operations within the Iranian port system. Employing a qualitative grounded theory approach, fifteen in-depth semi-structured interviews were conducted with managers of the Ports and Maritime Organization, private service providers, and shipping companies.

The findings led to the development of a multi-layered paradigm model integrating causal, contextual, and intervening conditions that influence outsourcing strategies, including decisions on full versus partial outsourcing, regional versus cluster-based allocation, and non-profit versus for-profit contractors. The results indicate that successful outsourcing depends on aligning private sector maturity, regulatory clarity, and financial incentives with national maritime governance structures.
