The history of humans creating and utilizing machines for transportation purposes dates back from the invention of the wheel to more recent innovations such as bicycles, automobiles, traffic signals, handheld navigation devices, asphalt pavers, and computer-aided design and management tools. In recent years, technological advancements have transformed machines from passive tools into more active participants, with humans increasingly delegating complex tasks and responsibilities to them. While these advancements have revolutionized mobility, their siloed, uncoordinated implementation has also introduced critical challenges, including urban sprawl, high fatalities, environmental degradation, and worsened societal disparity.</div><div>The recent advancements in machine learning, robotics, communication, and computing technologies prompt the emergence of agentic transportation systems (ATS) to potentially address these chronic issues and transform how people access resources and opportunities. In ATS, intelligent machines serve as autonomous intermediaries, facilitating the interactions among humans and between humans and infrastructure. From this new standpoint, early-stage ATS—such as autonomous vehicles, on-demand ridesharing platforms, generative design tools, construction robots, and anomaly detection equipment—have already begun to enter society, calling for an understanding about whether the current research and practice in transportation planning and engineering are ready for ATS. A review of recent literature reveals four main categories of research: (1) co-visioning, co-planning, and co-design; (2) co-construction and co-maintenance; (3) co-control, co-operation, and co-management; and (4) co-usage and co-consumption. The review suggests a significant lack of studies on the proactive integration of agentic machines within and across individual lifecycle phases, risking severe and irreversible consequences. Accordingly, the paper proposes a framework to guide the development of ATS to be justifiable, inclusive, and adaptable (JIA) and ensure the intelligence <em>in</em> and <em>of</em> the next-generation HMTS to be genuinely human-centered and societally beneficial.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"171 ","pages":"Pages 78-97"},"PeriodicalIF":6.3,"publicationDate":"2025-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144221087","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 literature on subsidies for resident passengers highlights their inefficiencies since they may imply increases in fares and non-residents' exclusion. This paper analyses the optimality of blind tickets - cheap surprise flight tickets without knowing the final destination - to manage those inefficiencies. This pricing strategy allows airlines to discriminate between resident and non-resident passengers by creating two different markets - one transparent and the other opaque. While resident passengers may be better off because of additional discounts, non-residents, who were excluded from the market, are now able to fly by purchasing blind tickets. We prove that, unless the proportion of residents is very low, blind tickets always imply an increase in social welfare and that this increase does not depend on passengers’ risk attitude. To illustrate this welfare improvement due to blind tickets under different market conditions, we include some numerical examples based on real data from Spain, where residents of the Canary Islands, Balearic Islands, and the autonomous cities of Ceuta and Melilla receive a 75 per cent discount on flight ticket fares.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"171 ","pages":"Pages 140-156"},"PeriodicalIF":6.3,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144240115","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}

Nonetheless, many collaborative efforts have failed due to financial restraints and low ridership. The failure of many of the integrated systems can be ascribed to the ineffective pre-implementation evaluation of the integrated system. The lack of a reliable performance evaluation tool capable of assessing the integrated system’s performance prior to implementation could be the case of such failures. Considering this gap, this paper proposes a support tool for decision process of multimodal integrated transport system that examines the viability of an integrated mobility service system comprised of a Fixed Route Transit (FRT) service system and on-demand services. The decision process is powered by an agent-based simulation framework that tests scenarios covering various modal integration strategies. The on-demand services could be Demand Response Transit (DRT) and Transportation Network Company (TNC) services, that particularly act as feeders for FRT to ensure first and last-mile connectivity. This study proposes four integration-strategies with ten potential integration scenarios and four non-integration scenarios, comprising a total of fourteen possible scenarios to complete a trip between any origin–destination pair. Using the agent-based simulation model, various scenarios can be constructed for origin–destination pairs, and based on the generalized system cost, the preferred integration strategy can be selected. The proposed model analyzed the generalized system cost for each scenario by incorporating three key cost components: user cost, agency cost, and external costs. The proposed method was implemented on two different networks, which are the Sioux Falls network and a real-world case study of the Morristown city network in Tennessee, United States. Simulation outcomes indicate that 69% of trips in the Sioux Falls network and 73% of trips in Morristown could be connected to the existing FRT network using feeder services as first and last-mile connectivity solutions. The results suggest that a properly evaluated integrated system could enhance the accessibility of FRT significantly. Therefore, the proposed methodology assesses the advantages of the integrated system prior to its implementation, assisting transit planners and policymakers in the efficient execution of integration strategies and enhancing user experience and mobility.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"171 ","pages":"Pages 28-49"},"PeriodicalIF":6.3,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144189350","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}

This study analyzes municipal climate actions alongside 2021 Canadian federal election results to assess four policy levers designed to shift transportation behaviours. Four key findings emerge: 1) left-leaning and larger municipalities favor voluntary actions to support fuel and modal shifts; 2) levers involving price signals or mandates are less frequently implemented across political ideologies and population sizes; 3) policies targeting fuel and modal shifts correlate positively with population size; and 4) the political spectrum is associated with modal shift policies but not fuel shift policies. These insights highlight the impact of political inclination and population size on adopting sustainable transportation policies. Municipal regulators should consider these factors in their planning efforts. The findings also suggest that strategies involving price signals or mandates may face resistance, highlighting the need for a more nuanced approach.

We studied a PVE application in which 2466 participants provided recommendations to the government about decision-making regarding Schiphol Airport, the Netherlands. Stakeholders were involved in many phases of and decisions on the PVE design process. The aim of this research was twofold.

However, a notable difference is that the design phase of the PVE involved several feedback rounds which made it much more time-intensive than other cases. Hence, the benefit that PVE requires low time investment of civil servants that emerged in other studies was not applicable when applying PVE to an institutionalized transport conflict setting. Furthermore, stakeholders could not agree on various design choices of the PVE. To satisfy the diverging requests of stakeholders a very lengthy PVE was constructed.

This study examines the development impact of new terminal construction with city-aiport expressway connection projects by analyzing changes in nighttime light intensity (NTL) along the new ground transportation corridor in Ha Noi, Viet Nam. In this microgeographic impact analysis, NTL is assumed to indicate the degree of urban economic activity or development.

Based on a quasi-experimental design framework, difference-in-differences (DID) estimation techniques were applied to pursue causal inference. The results of the DID model analysis present that the impact of new terminal construction with city-airport expressway connection projects on NTL is significantly positive near the new ground transportation corridor. An additional analysis further reveals that the NTL impact tends to be greater near the city center, significant regardless of residential density, and significant in already well-developed locations.
