The rapid growth of electric vehicles (EVs) and rooftop photovoltaics (RPVs) is transforming urban energy systems, their combined impacts on city-level power load demand remain underexplored. This study develops a scenario-based framework to evaluate combined impact of vehicle-to-grid (V2G) discharging strategies and RPV deployment on representative weekday hourly net load, peak and valley loads, and load fluctuation intensity across 41 cities in the Yangtze River Delta (YRD). Results indicate that the combined strategies integrating orderly EV charging and discharging with RPV generation in scenario S9 can reduce the peak load by approximately 21.9 GW, lower the peak–valley difference to around 51.6 GW, and reduce the load fluctuation intensity by approximately 50 % compared with the baseline scenario in 2030 in YRD region. Lower electricity demand cities, such as Lianyungang, exhibit up to 70 % reductions in midday load, whereas high-load metropolitan areas, such Shanghai, show relatively limited improvements. However, when an excessive number of EVs participate in V2G or the RPV penetration becomes too high, load may experience stronger fluctuations. Policy recommendations include promoting coordinated EV charging and discharging, and the integrated deployment of RPV and energy storage systems to enhance energy system resilience.

Connected autonomous vehicles (CAVs), which can self-relocate, seem to be able to alleviate the shortage of parking supplies at the trip destinations. However, in the mixed phase, before CAVs fully replace human-driven vehicles (HDVs), social managers still need to consider the imbalance between supply and demand for parking of HDVs. To allocate parking resources more efficiently, this paper proposes a parking dispatch system, which dynamically dispatches CAVs among different parking lots to change the distribution of parking demand. An agent-based modelling approach is presented with the consideration of CAVs mixed with HDVs. Using trip data from Hangzhou, we evaluate the effects of the parking dispatch system under different CAV penetration and parking supply. The results show that the dispatch system is effective in improving the parking experience for HDVs and can reduce operating cost for the whole society. The proposed dispatch-based strategy will help to enrich the theory and methodology of parking management for the mixed era.

Traditional assessments of port resilience often overlook vessel scheduling dynamics within port areas and fail to incorporate spatiotemporal perspectives alongside statistical data, particularly under supply chain disruptions. This study integrates AIS data within Vessel Traffic Service (VTS) zones to propose a resilience assessment framework across five major global ports, evaluating vulnerability, robustness, and recoverability using one statistical indicator (throughput) and three spatiotemporal metrics (vessel count, transit time, scheduling frequency) during COVID-19.Through Seasonal-Trend Decomposition using Loess, the study quantifies disruption phases, revealing that vulnerability and robustness periods last 1.02–2.63 months, while recovery last 1.02–2.63 months. Among the cases, Shanghai exhibited the highest vulnerability, whereas Ningbo–Zhoushan and Singapore demonstrated the fastest recovery. Further, a threshold model reveals a nonlinear marginal relationship between throughput gains and port scheduling efficiency. Under high operational stress (>71.34 %), optimal VTS transit times (47.99–94 h) yield peak throughput of ∼68,000 tons per vessel. However, scheduling flexibility remains constrained by environmental and infrastructural limitations, particularly for large vessels at Hong Kong and Shenzhen. These insights demonstrate the value of real-time AIS analytics in capturing operational adaptability and guiding strategic planning to enhance port resilience in an era of growing global trade uncertainty.

The transition to Sustainable Aviation Fuel (SAF) is a critical strategy for aligning China's aviation sector with global climate commitments. This study develops an integrated economic–environmental–energy complex-system framework for airlines and employs a system dynamics approach to simulate the economic viability and development potential of China's current SAF pilot policy, using Beijing as a case study. The model further explores optimized policy pathways. Key findings indicate that: (1) Airlines' economic contribution is highly vulnerable to external shocks, such as the COVID-19 pandemic; (2) While the existing 1 % SAF blending pilot policy is economically viable in the short term due to its limited adverse impact, its long-term sustainability is questionable as economic contribution begins to decline markedly after a post-pandemic inflection point; (3) Increasing the SAF blending ratio gradually erodes airline profits, as cost pressures from SAF adoption outweigh potential benefits like carbon emission reductions and partial cost pass-through to passengers, which is influenced by price elasticity of demand; (4) While a basic subsidy for SAF use is marginally effective, only when subsidies cover 70 % of SAF costs do airlines begin to recover profitability with SAF blending, albeit with diminishing returns over time; (5) An additional subsidy tied to emission reduction efficiency significantly enhances airlines' economic contribution, with more pronounced long-term benefits. Based on these results, the study proposes an integrated and flexible policy combining dual-subsidy and production-side cost-reduction measures to balance short-term transition needs with long-term fiscal sustainability. By integrating multidisciplinary perspectives and adopting a complex-system framework, this study offers theoretical and practical innovations—providing evidence-based insights for policymakers and airline managers in designing effective SAF transition strategies.

The dual credit policy (DCP) has become a key instrument in promoting the development of the electric vehicle (EV) industry. Within EV supply chains, power batteries, being the most critical and cost-intensive component, play a decisive role in shaping the industry’s competitive dynamics. This study examines how variations in power structure influence the effectiveness of the DCP and the strategic behavior of supply chain participants. Specifically, it analyzes an EV supply chain comprising a power battery supplier and two manufacturers under both decentralized and alliance-based decision-making frameworks. Furthermore, the study explores how power dynamics affects the decision-making behavior of supply chain members and evaluates the policy’s effectiveness. The main findings are as follows: (1) An increase in the new energy vehicle credit coefficient and credit trading price enhances the revenues of all EV supply chain participants, with stronger effects observed for those in dominant positions. (2) Forming an alliance consistently promotes the improvement of battery technology, regardless of the underlying power structure. However, the lowest level of technological advancement occurs when either the supplier or its alliance takes the leadership role. (3) Although alliances contribute to expanding overall market demand, they do not necessarily enhance the benefits of all participants. Only when the alliance assumes a leading position do its benefits exceed those achieved under decentralized decision-making. These findings provide valuable implications for policymakers and industry stakeholders seeking to optimize cooperative and competitive strategies and to leverage the DCP more effectively in fostering sustainable growth within the EV sector.

Recently, the presence of Advanced Driver Assistance Systems (ADAS) on passenger cars has become extensive, also prompted by EU regulation mandating their inclusion in new vehicles. While ADAS are effective in reducing crash frequency, there is growing concern about a potential risk compensation effect — namely, that drivers or passengers may engage in riskier behavior due to a perceived increase in safety when ADAS are present. This study evaluates the trade-offs made by youths when assessing the risk of riding with a driver under the influence of alcohol, in the presence or absence of ADAS. We develop a discrete choice experiment and estimate several discrete choice models, including latent class and hybrid choice models. Our findings suggest that many respondents perceive ADAS as mitigating the danger associated with higher alcohol intake, implying that the presence of ADAS may unintentionally lower perceived risk and potentially encourage risk-taking behavior. Both model types reveal heterogeneity in preferences, with a significant association between perceived negative consequences of drink driving and the mitigating effect attributed to ADAS. Policy implications are discussed.

This study examines competitive advantage in the aviation sector within the context of resource dependency theory, specifically focusing on the ground handling services sector. The aim of the study is to identify the resources on which ground handling services companies depend within the context of resource dependency theory, to examine the competition experienced in the sector, and to determine the strategies used to achieve competitive advantage. The scope of the study consists of Group A ground handling companies operating in Türkiye. A qualitative research method was used in the study, and the data collected using semi-structured interviews were analyzed with the MAXQDA2020 program. The analysis revealed that the ground handling sector in Türkiye is costly and volatile, while competition in the sector is balanced and low. In ground handling companies, there is a greater reliance on outsources such as equipment, training, and workforce-human resource. The high cost of resources, regulatory compliance, frequent audits, and lack of alternative suppliers create a situation of forced dependency. Although competition within the sector is balanced and low, the competition between companies cannot be ignored. Ground handling companies generally provide services that are standardized by regulations and do not vary greatly, but they have advantages over their competitors in cargo-warehouse services and platinum services. In addition, ground handling companies have advantages in terms of sustainability, safety, and size. In this regard, ground handling companies implement collaboration-focused, quality-focused, cost-focused, and customer-focused strategies to gain a competitive advantage. Effective management of the procurement process for resources used in the ground handling services sector and dependency relationships related to resources provides companies with a competitive advantage. Companies manage dependency relationships by incorporating available resources into their own structures. However, due to the specialized areas of expertise, the necessity of the relationship, and the high costs involved, companies resort to outsourcing when necessary.

The 2024 electric vehicle distance-based charge introduced in Victoria, Australia, to recognise that such vehicles do not pay fuel excise tax, led to a high court challenge in which it was deemed unconstitutional for a State to introduce such a charge, which is the responsibility of the Federal government (through legislation amendment). This loss of fuel excise as a tax (not a charge) on electric cars whetted the appetite of the Federal Government to place road user charging on a round table in August 2025. We now have elevated the topic right into the political sphere where any change will require such support, and it opens up an opportunity to not only consider the fuel excise issue per se but the broader agenda on road pricing reform.

Transportation equity is pivotal for improving access to healthcare, economic opportunities, and everyday well-being within sustainable cities and communities, particularly for low-income, elderly, and disabled populations. This paper examines Florida's state-funded Transportation Disadvantaged (TD) Program in the United States, with a particular focus on Miami-Dade County, to highlight how fare-free and subsidized transit access can reduce systemic barriers to mobility. Drawing on a synthesis of existing evaluation reports, administrative records, service plans, and articles, the paper discusses how the TD Program improves access to healthcare, employment, and social participation while alleviating financial burdens. It argues that such programs are critical tools for increasing access to essential services, reducing social exclusion, and promoting the well-being of the TD population in car-dependent urban contexts. The paper proposes an equity-oriented framework to support inclusive, outcome-based transport planning and program evaluation by linking activities to measurable outputs and long-term outcomes. The framework highlights the importance of sustained funding, cross-sector coordination, and user-centered evaluation for equitable transport planning. Insights from the TD Program synthesis and the proposed framework align with the Sustainable Development Goals, supporting inclusive and sustainable urban development. As cities in the United States and worldwide face growing mobility disparities, the need for inclusive solutions becomes increasingly urgent. In this context, the equitable public transport policy and TD Program offer scalable insights for building accessible and equitable urban transport systems that better serve transport-disadvantaged and vulnerable populations while advancing sustainable urban planning.

In this context, the equitable public transport policy and TD Program offer scalable insights for building accessible and equitable urban transport systems that better serve transport-disadvantaged and vulnerable populations while advancing sustainable urban planning.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"177 ","pages":"Article 103931"},"PeriodicalIF":6.3,"publicationDate":"2025-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145738231","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}

Congestion charging systems have emerged as a promising policy tool for mitigating traffic congestion and reducing emissions in urban areas. This study applies a dynamic activity scheduling model to assess the effects of congestion pricing in the Greater Helsinki region. By simulating daily activity patterns and travel behaviour, we analyse the impacts of congestion charges on mode choice, destination selection, and departure time adjustments. Our findings reveal a 10% reduction in car use and a 27% decrease in total car kilometres travelled, demonstrating the effectiveness of congestion pricing in alleviating traffic congestion. However, the analysis also highlights the potential equity concerns, with impacts varying across locations and commuting patterns. These insights contribute to the growing body of evidence on the behavioural and distributional consequences of congestion pricing, offering valuable guidance for policymakers.
