Dynamic pricing and passenger flow assignment were placed into the same framework to achieve collaborative optimization. On the demand side, the space-time service network for the train timetable was constructed. A bidirectional breadth-first reasonable route search algorithm and passenger travel choice cost formula were proposed. The passenger choice behavior parameters were derived from revealed preference (RP) and stated preference (SP) surveys. On the supply side, differentiated train products were classified by the station level and the station number and were connected to the fare adjustment strategy. To solve the comprehensive optimization problem of dynamic pricing and passenger flow assignment, a differential pricing biobjective comprehensive optimization model was developed, and a multidimensional passenger flow assignment strategy was employed. Based on real data, the <em>Beijing–Shanghai high-speed railway</em> was used as a case study, and the station level, OD (Origin-Destination) level, train classification, fare adjustment strategy, enterprise revenue, train indices and OD fare were analyzed. The case study verified the effectiveness of the fare adjustment strategy based on differentiated train products and provided a novel approach for the marketization of high-speed railways.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"165 ","pages":"Pages 107-126"},"PeriodicalIF":6.3,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143474644","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}

While they serve various functions, the needs of certain uses—such as freight—often have been overlooked in space allocation policies affecting urban livability. Recently, freight curbside management has emerged to address these conflicts, allowing service and delivery vehicles to better use street space, contributing to cities’ sustainability targets. Although pilots testing freight curbside interventions are a first step for policymakers to evaluate the effectiveness of these interventions, the transition from pilot to established practices remains underexplored. Therefore, the aim of this research is to understand the success and failure factors that influence the institutionalization process of interventions tested in freight curbside pilots. To achieve this, this paper analyses cases from various cities worldwide that have implemented such pilots, using the lens of institutional theory. Case selection criteria were based on the maturity level of freight curbside pilots. Specifically, the paper focused on those cases that had already implemented pilots, undergone monitoring, evaluation, and possible continuation processes. Data collection and analysis revealed coercive, normative, and mimetic forces driving change towards institutionalized practices. The data analysis identified 23 themes across four content domains, i.e., organizational, economic, technological, and regulatory. Successful institutionalization process relies on strategically selecting high demand loading zones and demonstrating public benefits. Enhancing user experience is also crucial. However, some interventions fail to become institutionalized due to regulatory constraints, business model issues, and land use regulations. This highlights the need for flexible, context-specific approaches. The analysis of institutional pressures revealed that coercive pressures influence transitions from themes related to the legal mandate of public agencies, pilot scope definition, and user experience, while normative pressures shape transition regarding public benefit, business models, stakeholder involvement, and data management themes. Mimetic forces guided early-stage pilots through lessons learned from cities with prior experience in curbside pilots. The findings provide recommendations and guidelines for the development of future pilots, useful for planners aiming at generating long-term curbside policies that solve freight-related street space conflicts.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"164 ","pages":"Pages 244-254"},"PeriodicalIF":6.3,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143378079","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}

This issue is further exacerbated by the prominent role of subnational governments in public transport governance, as they dispose of fewer resources than their national counterparts. This study introduces an international methodology for evaluating the efficiency of urban bus systems in 50 cities across Brazil, France, Spain, and the USA. The systems were further categorized by population size. The methodology utilizes crew, energy consumption, fleet, CO2 emissions, and urban population as inputs, while fare revenues, catchment area, and ridership serve as outputs. Data Envelopment Analysis (DEA) was applied to the sample across various scenarios. European systems demonstrated the highest efficiencies. Large European and non-large Brazilian systems were the most resilient though different regions displayed sensitivity to distinct metrics.

However, the impact of this development on carbon lock-in (CLI) and carbon unlocking remains under-explored, which is an area critical for understanding the potential of HSR in mitigating climate change. This study addresses this gap by analyzing data from 256 prefecture-level cities in China between 2009 and 2021. Urban CLI levels are quantified by a projection pursuit model based on genetic algorithms. Additionally, a High-Speed Rail Connectivity Index (HSRCI) is introduced to assess the current state of China’s HSR network. Our findings reveal that the HSR network effectively promotes carbon unlocking, especially in large and medium-sized cities, non-resource-based cities, and transportation hubs. It suggests that developing the HSR network can mitigate the increased carbon emissions associated with traditional transportation modes, thereby playing a crucial role in achieving China’s “dual carbon” goals. Furthermore, mechanism analysis indicates that increased urban economic density and population aggregation facilitate the expansion of the HSR network, effectively reducing CLI. Moreover, regional integration and innovation improvements significantly enhance the HSR network’s carbon-unlocking effect. Conversely, higher levels of fixed asset investment may, in some instances, exacerbate CLI. This study provides empirical evidence and policy recommendations to optimize the HSR network’s carbon-unlocking potential.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"164 ","pages":"Pages 144-159"},"PeriodicalIF":6.3,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143323942","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}

Three representative transportation technologies–<em>electronic toll collection systems</em>, <em>ride-sharing platforms and fully autonomous vehicles</em>–are compared. Data were collected using a questionnaire administered to 524 participants. The findings revealed that, while these technologies allowed consumers’ significant freedom perception, they also introduced new dependencies, invoking a perception of enslavement. Surprisingly, the induced learning tensions showed a positive relationship with technology adoption, which suggests that the challenges encountered during the learning process can enhance user engagement and acceptance. Furthermore, the study emphasised how perceptions of freedom and enslavement evolve with technological advancement in different transportation contexts, indicating their complex interplay with technology adoption intention. The findings enhance our understanding of the technological paradox theory and elucidate the dual role of learning tensions.

To achieve these objectives, the total credits issued are typically set below actual travel demand, thereby encouraging a mode shift from private cars to more sustainable alternatives, as well as promoting trip avoidance or postponement. A central aspect of TCS is, therefore, determining how credits are allocated to individuals—and, specifically, whether all users should receive the same credit budget. However, the literature offers limited research on the strategies, central elements, and user preferences related to the initial credit allocation. In this paper, we review the building blocks of the initial credit allocation in Tradable Mobility Credit Schemes, namely: (a) the eligible receivers, (b) the credit measurement unit, (c) the validity period and transferability of credits, and (d) the allocation method itself. Additionally, we present empirical findings on public support for non-uniform credit allocation strategies and preferences regarding credit compensation for various individual attributes. Our survey results show that approximately 70% of respondents endorse the non-uniform allocation of credits. Support was particularly high among individuals with limited public transport accessibility, lower incomes, and women. Besides, respondents identified mobility impairment, care work responsibilities, and poor public transport accessibility as the most critical factors that should influence the credit budget an individual receives.
