Studies have identified EV charging as a major barrier to EV adoption. We analyse public opinion related to EV charging to understand perceived charging-related barriers and successes. We extract EV charging related posts from Twitter using a pipeline based on BERTopic and Large Language Models, with manual review, to create a thematic structure driven by the data, then analyse these themes using message sentiment and volume. Strong interest and positive sentiment exists around charging technologies and public infrastructure deployment, indicating hope for the future of EV adoption and public deployment meeting demand. Negative opinion exists around blocked and broken chargers, the impact of cold climate, EV ”subsidies” and since 2020 a weakening of the economic argument for EVs. Home charging is viewed enthusiastically by those with access to it and as a barrier and inequity by those that do not. Green issues received the least interest of all our themes.

The negative impacts of air pollution and its environmental, economic and social damages to metropolises are among urban management challenges. One of the most economically effective tools for environmental management and pollution control is payments for ecosystem services (PES). In this study, we have proposed the framework and requirements of PES to reduce Tehran air pollution using one of the most practical methods for reducing emissions of gaseous pollutants i.e. replacing passive catalytic converters in light vehicles in Tehran. For this purpose, we have investigated the owners’ willingness to participate in PES, the cost of replacing the converters and Tehran residents’ willingness to pay to reduce air pollution. The study results showed that on average, 71.3 % of Tehran citizens in the study sample agreed to pay. The willingness to pay per person has been calculated at 912 thousand Rials per month. Also, a significant percentage of owners agree to participate voluntarily to replace catalytic converters. The data presented in this study provided the framework of PES to reduce Tehran air pollution through urban management institutions and government participation in financing under various scenarios.

This research examines the effects of different immersive media formats—virtual reality (VR), video, and photos—on air taxi acceptance, notably concerning immersion’s ability to affect users’ perceptions and decisions. This study applied factors from the UTAUT2 model to explore how these media conditions trigger performance expectancy, effort expectancy, hedonic motivation, social influence, and reliability. The results show significant differences in the quality of immersion, with VR being the best. No differences were found in the intention to use air taxis across media formats. However, in the VR condition, the decision-making process included taking more emotional factors into account. These findings highlight the usefulness of both emotional and utilitarian factors when considering technology acceptance and, therefore, the potential of VR to increase user engagement despite a lack of impact on immediate usage intention. The research recommends further studies on the long-term effects of immersion and individual characteristics influencing the acceptance of technologies.

In the realm of transportation infrastructure, Weigh-in-Motion (WIM) stations are crucial for monitoring impact of overweight trucks and maintaining infrastructure assets such as roadway pavements and bridges. However, current approaches to WIM location problem (WIMLP) on a network of highways and bridges are often region-specific and resource-intensive and lack a multi-objective framework. This study addresses these gaps by proposing a versatile and cost-effective network-based site selection strategy, adaptable to various transportation agency needs. Utilizing an extensive literature review, the framework centers around a comprehensive site-selection framework based on the diverse purposes of WIM data collection. The proposed framework integrates truck traffic composition, infrastructure condition, enforcement needs, and geographical considerations. This approach strategically identifies the optimal sites for WIM installation, maximizing data utility while minimizing resource expenditure.
The proposed framework for WIMLP is showcased in New York City, addressing the city’s challenge of managing truck load impacts on its extensive bridge network. Based on the City’s allocation of resources for only ten sites, the research team strategically identified their respective optimal WIM locations across the city’s roadway network and highway bridges. This selection facilitates the assessment of truck load effects, especially from overweight vehicles, on bridge conditions. This approach not only aids in long-term infrastructure monitoring aligned with NYCDOT’s goals but also supports future overweight enforcement efforts. Additionally, the study introduces an analytical framework to enhance the utilization of WIM data in analyzing truck load impacts.

As mobility systems evolve, their design must enable people to adapt to disruptions in their daily lives and routines, making social resilience a vital yet underexplored focus. This is why this study investigates the question: What are the challenges when designing for social resilience in local mobility services? Semi-structured interviews with seven mobility experts revealed the need for a shift from prioritising organizational resources to enhancing social capacity, emphasising individuals’ strengths and established routines. The main challenges for urban planners and developers to achieve this were identified through a lack of guidelines for incorporating social sustainability into mobility planning, that in turn renders difficulties in employing qualitative methods tailored for enabling citizen and stakeholder engagement, as well as developing deeper understandings of local, social life. These findings are illustrated in this article through five design implications, each highlighting strategies to integrate social resilience into mobility systems, ensuring they are responsive and supportive of the communities they serve.

We contribute to the literature on new mobilities by measuring spatial disparities in travel times for accessing essential non-work destinations via ridehailing. We focused on healthcare, restaurants, and grocery destinations in Chicago. Data from Chicago ridehailing providers, which included detailed information about all realized ridehailing trips in Chicago, were used to derive mean travel times by ridehailing for each census tract. Inspired by the gravity-based model, we calculated an inverse travel time index based on cumulative travel times for each census tract where ridehailing trips occurred. To understand the disparities in travel times, we compared the inverse travel time index for ridehailing and transit in the same census tracts. Then, we applied spatial autoregressive regression to examine the effects of various sociodemographic factors. The results suggested that the inverse travel time index was preferable in tracts with a higher household income and a lower percentage of minority populations. Also, disparities in travel times tended to be greater via ridehailing than transit. This study sheds light on disparities related to ridehailing and how we could improve access to essential destinations for underserved and underrepresented populations and communities. Policy implications include subsidizing disadvantaged users who lack reliable transportation options, regulating ridehailing prices, increasing the provision of essential destinations for underserved areas, and maintaining the quality of public transit services.

Precision Teaching (PT) is a data-driven educational technique that continuously monitors and adjusts instruction to achieve specific, measurable learning outcomes. This research applies PT principles to train drivers in improving lane maintenance behaviour, focusing on the comparison between feedback delivery modalities, to fill a gap in prior literature due to limited and somewhat conflicting findings.
This study builds upon a previous study, expanding the analysis to encompass a larger cohort of drivers and introducing a new experimental condition. Overall, 80 participants were involved in a driving simulator study in which they were asked to perform four consecutive trials, the first without feedback and others with feedback delivery.
Participants were divided into three groups, each assigned to an experimental condition based on feedback administration: Auditory (A), Visual (V), and combined (VA). All systems provided contingent negative/positive feedback based on participants’ lateral position.
A MANOVA was conducted, with feedback type and trials serving as independent variables. The analysis considered six dependent variables, incorporating four indicators for lane maintenance, along with two variables, mean speed and acceleration, to assess potential indirect effects.
Results reveal that all tested conditions were effective. However, conditions A and VA demonstrated greater effectiveness in reducing the standard deviation of lateral position. The auditory feedback system seems to emerge as the most promising option, likely being less intrusive since it delivered fewer stimuli compared to VA. These findings could be valuable in shaping the design of PT protocols for real-time coaching programs for eco-driving or within usage-based insurance schemes.
精准教学（PT）是一种数据驱动的教育技术，可持续监控和调整教学，以实现特定的、可衡量的学习成果。本研究将精准教学原则应用于培训驾驶员改善车道保持行为，重点是比较不同的反馈方式，以填补以往文献中由于研究结果有限且存在一定冲突而造成的空白。本研究以之前的一项研究为基础，扩大了分析范围，纳入了更多的驾驶员，并引入了新的实验条件。共有 80 名参与者参与了驾驶模拟器研究，他们被要求连续进行四次试验，第一次试验没有反馈，第二次试验有反馈：参与者被分为三组，每组都根据反馈管理分配到一种实验条件：听觉（A）、视觉（V）和综合（VA）。所有系统都根据参与者的横向位置提供或有的负面/正面反馈。进行了 MANOVA 分析，将反馈类型和试验作为自变量。分析考虑了六个因变量，包括车道保持的四个指标，以及平均速度和加速度两个变量，以评估潜在的间接影响。然而，条件 A 和 VA 在减少横向位置标准偏差方面表现出更大的有效性。听觉反馈系统似乎是最有前途的选择，因为与 VA 相比，听觉反馈系统提供的刺激更少，所以干扰性更小。这些研究结果对于设计生态驾驶实时指导计划或基于使用的保险计划中的PT协议很有价值。

This paper explores the implications of carbon-taxing policies on food supply chain affordability and competitiveness in Canada. Initiated with Alberta’s 2007 carbon levy, Canada’s approach to carbon taxation aims to mitigate greenhouse gas emissions while addressing the economic impacts on the food sector. With the federal carbon price set to rise to CAD $170 per ton by 2030, the study investigates the potential for increased food prices and the challenges to food affordability as well as identify the current gaps in understanding the intricacies of Carbon Taxing Policies on the Food Supply Chain in Canada. Graphic analyses and forecasts were created using data from Statistics Canada and the U.S. Census Bureau. The main findings of the analyses reveal shifts in wholesale and industrial prices since the carbon tax’s implementation. Findings suggest that carbon pricing may be affecting every level of the food supply chain, highlighting the need for further research to understand its full impact on food affordability and security.

Many developing countries are at a crucial juncture in road transport electrification with electric mobility because they have limited economic capacity to implement government policy support and financial mechanisms that have spurred the capital-intensive electric mobility growth in developed countries. Attracting private sector investments remains a viable option for developing countries. While investors have identified opportunities to invest in developing countries, it remains to be seen which countries to prioritise, considering the complexities involved in investment decision-making despite the availability of myriad investment appraisal tools. This paper contributes to this academic and policy debate. With a power and transport sector coupling viewpoint, we explain the interaction of the power and transport sectors in the context of decarbonisation and digitalisation to identify developing countries that could be considered for private sector investment in electric mobility. Then, we apply our framework to case studies of the Philippines, Argentina, Romania, and Poland. We argue that countries with wholesale power markets and wholesale and retail power markets could attract electric mobility investment. We offer policy recommendations to stakeholders interested in electric mobility investment issues in developing countries.

Public transport services are often designed to meet travel demand under regular situations. However, severe weather conditions (e.g., heavy rainfall, snow, thunderstorms, etc.) can adversely impact the service operation, leading to problems such as in-vehicle overcrowding, delays, and trip cancellations. In this study, we propose a novel approach to address in-vehicle overcrowding issues during weather disruptions. In this approach, we dynamically reassign buses from low-demand trips to lines where the expected demand exceeds the capacity threshold of the in-service buses. This way, the existing capacity is utilized more efficiently without requiring additional vehicles or drivers. Considering the shortage of bus drivers in Europe, as well as in the Netherlands, this is a more efficient solution than other alternatives such as deploying additional buses from the depot. Experiments were conducted on a bus network in Enschede in the Netherlands. The results showed that in several disrupted situations, we can reassign bus trips to overcome overcrowding issues without significant negative impacts on the operation or passengers. However, the approach entails a trade-off between passengers of a canceled trip and an overcrowded trip. Some passengers must wait for the next bus or use other means of transport as a consequence of bus reassignment.

However, severe weather conditions (e.g., heavy rainfall, snow, thunderstorms, etc.) can adversely impact the service operation, leading to problems such as in-vehicle overcrowding, delays, and trip cancellations. In this study, we propose a novel approach to address in-vehicle overcrowding issues during weather disruptions. In this approach, we dynamically reassign buses from low-demand trips to lines where the expected demand exceeds the capacity threshold of the in-service buses. This way, the existing capacity is utilized more efficiently without requiring additional vehicles or drivers. Considering the shortage of bus drivers in Europe, as well as in the Netherlands, this is a more efficient solution than other alternatives such as deploying additional buses from the depot. Experiments were conducted on a bus network in Enschede in the Netherlands.
