The results show that frequent teleworkers tend to substitute in-store grocery shopping over weekends with online grocery shopping, especially during workdays, while also being more inclined to order meals online, in general, than to eat out on weekends. This behavior presents a stark contrast with those showing an in-store preference. In-store shopping preference is positively associated with activities to which telework frequency is negative or non-significant, such as shopping in-store for groceries on weekends and eating out on workdays and weekends. In-store shoppers will be older non-teleworkers, with older, less educated, and less affluent individuals being the ones less likely to telework and more likely to hold to previous habits built around a commute. Moreover, since non-teleworkers with a preference for online shopping also engage in meal deliveries during workdays and online grocery shopping on weekends, the expected delivery uptake can potentially impact residential areas through (e.g.) increased noise, curbside occupation and pedestrian-vehicle conflicts. These shifts in workplace preference and preferred shopping channels will influence travel demand, the location of economic activities, and how cities are structured, and will have to be considered in the development of policies that maximize their benefits while mitigating potential adverse effects.</div></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":"195 ","pages":"Article 104461"},"PeriodicalIF":6.3,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143747160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The data collected serves as the basis for conducting two ordinal regressions. The results show positive associations between participants’ perceived potential to overcome space and time accessibility barriers thanks to internet and their internet-related perceptions. In particular, for housing beneficiaries travelling longer distances, positive perceptions towards internet might result in a positive perceived potential to overcome both space and time accessibility barriers. From the socio-economic side, young participants are more likely to perceive that they can overcome space and time barriers thanks to the Internet, while highly-educated people only spatial barriers.

Bucharest is considered an appealing case study given the fact that it is facing significant issues with regards to the topic of transportation, emissions and segmented urbanization development, having one of its districts included in the “100 Climate-Neutral Cities by 2030” mission. Using geospatial analysis, statistical descriptions, and cluster analysis performed in Python, access to essential services such as education, healthcare, cultural activities, and mobility across six districts is assessed. The analysis is structured around four composite indices: Accessibility to Learning and Healthcare, Wellbeing and Quality of Life, Essential Services and Mobility, and Food Access and Provision. The findings indicate that District 2 is the most closely aligned with the “15-minute city” criteria, as it demonstrates a high level of service accessibility. Conversely, peripheral districts, such as District 6, demonstrate restricted access to mobility and healthcare services. Cluster analysis further confirmed the disparities between districts in terms of access to infrastructure and services, highlighting the necessity of targeted urban planning and investment.

One way to explore how social media and policy diffusion are linked is to review the government posts on different topics of the policy over time. To investigate the diffusion dynamics of NEV policies, this study proposes a central-local government interaction analysis, leveraging the government posts on social media. Dynamic topic model is deployed to unveil the evolving nature and intergovernmental disparities of policy topics. Subsequently, a net directional connectedness model is employed to construct information overflow networks of different policy topics among governments. A comprehensive examination of 5386 text posts is conducted using the proposed method. It is identified that the central government prioritizes guidance policies, emphasizing industry support and global cooperation, while local governments concentrate on specific implementation measures, following a trajectory of infrastructure development, research and development, and tax exemptions. In the policy diffusion network, central government serves as the primary driver of promotional signals, followed by Shanghai, Guangdong and Beijing, while Chongqing acts as a key recipient. Simultaneously, successful local implementation can feed back experiential knowledge to central policy, constituting a dual-directional diffusion mechanism of NEV policies between the central and local governments. These findings offer valuable insights into the understanding and diffusion of NEV policy in the digital era, revealing the complex interactions across diverse regions and administrative levels.</div></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":"195 ","pages":"Article 104459"},"PeriodicalIF":6.3,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143739529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In response to these emerging requirements, high-definition (HD) maps have quickly risen to prominence. However, current HD maps primarily focus on road data and often simplify roadside rest areas (RRAs) into points of interest (POIs), presenting challenges for intelligent vehicles navigating within RRAs. To address these challenges, this paper introduces a refined HD map model specifically tailored for RRA. It categorizes the traffic elements within RRAs into four distinct classes: roads, lanes, markings and signs, and service areas. Each class of elements is thoroughly defined and explained within the proposed map model. In practical RRA scenarios, the proposed map model is visualized and validated using map exchange formats and physical application formats. The introduction of the RRA HD map model not only ensures that vehicles can achieve intelligent driving within RRAs, but also contributes to the establishment of data management platforms for RRAs, providing travellers users with enhanced services.</div></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":"195 ","pages":"Article 104463"},"PeriodicalIF":6.3,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143725649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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 employs a correlated random parameters bivariate probit model with heterogeneity in means (CRPBPHM) to jointly analyze intercity travelers' simultaneous adjustments of departure dates and travel modes in response to adverse weather events. Empirical data are derived from stated preference surveys, which integrate adverse weather scenarios into intercity travelers' latest actual travel behaviors within the Beijing-Tianjin-Hebei urban agglomeration. The results reveal a positive correlation between adjustments to departure dates and intercity travel modes. Intercity travelers' adaptive behaviors exhibit multi-layer heterogeneity. Four variables—access time, departure city, monthly income, and education level—are identified as random parameter variables, with departure city and education level showing mean heterogeneity. The correlations between these random parameter variables further influence adaptive behaviors. Additionally, influencing factors and their interactions distinctly shape adaptive decisions. Key findings indicate that intercity travelers are more likely to adjust departure dates than travel modes in adverse weather. Snowy and windy conditions lead to more frequent plan modifications compared to foggy or rainy weather. Rain prompts travelers with visiting purposes or longer stays to adjust departure dates. Train users are less likely to change departure dates in foggy weather and are less likely to switch travel modes during snowfall. These findings enhance our understanding of intercity travelers' joint adaptive behaviors in adverse weather, providing valuable insights for precise and effective emergency management and ensuring secure and smooth intercity transport operations.</div></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":"195 ","pages":"Article 104462"},"PeriodicalIF":6.3,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143725648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using panel data from 280 Chinese cities from 2003 to 2019, we employ the time-varying difference-in-differences method to analyze the carbon emission reduction effects of both single and cooperative pilots and explore potential spatial spillover effects. Results show that single pilots significantly reduce carbon emissions in the implementing cities, with this effect being more pronounced in smaller cities and those with high-speed rail systems. However, the impact of cooperative pilots is not significant. Among the single pilots, cities that participated in the previous “Ten Cities, Thousand Vehicles” pilot achieved better carbon emission reduction outcomes, but this advantage is not evident in the cooperative pilots. Furthermore, when considering the spillover effects, both single and cooperative pilots significantly promote carbon emission reduction in neighboring cities, with cooperative pilots leading to a larger spillover effect than single pilots.

However, travel time use can also influence how people organise their daily schedules because travellers can perform activities that release time outside the journey, a behaviour we call “activity transfer” in this study. This research develops a comprehensive conceptual framework to investigate the determinants of travel time use and activity transfer. For that, we utilise a rich dataset of a representative sample (n = 1673) of the Greater Melbourne and Geelong population (Australia) and implement an Integrated Choice Latent Variable (ICLV) model. We model three mutually exclusive behaviours: (1) no engagement in travel time use; (2) travel time use without activity transfer; and (3) travel time use with activity transfer, during a trip towards the individuals’ main activity (e.g., work, study, or other main trip purpose). The ICLV results indicate activity transfer as a time-management strategy for people overlapping different roles and, thus, potentially having more time constraints. Conversely, travel time use without transfer seems to be a strategy for decreasing the dislike of travelling. Activity transfer is more likely to occur in passengerised modes (i.e., public transport and car passenger) with favourable travel conditions (e.g., seat availability) and less likely to occur on short journeys. Bringing laptops with an internet connection to the trip is associated with travel time use with and without activity transfer, while smartphones are predictors only of the latter. Importantly, after controlling for other time-use-related latent constructs, polychronicity becomes a weak predictor of travel time use and activity transfer, suggesting a potential omitted variable bias in previous research. By unveiling fundamental aspects of travel time use, our results have significant implications for transport practice, including public transport investments, long-distance travel modes, and passenger vehicle automation.</div></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":"195 ","pages":"Article 104460"},"PeriodicalIF":6.3,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143714323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A new lane management scheme, termed eco-lanes (ELs), is introduced in this study to provide a more flexible operational framework, enabling authorities to designate various vehicle access types across different road segments. We conceptualize ELs as instrumental in enhancing traffic flow efficiency and promoting the adoption of eco-friendly commuting practices. To assess the quantitative impacts of ELs on commuters’ mode and route choices on network operations, a combined mode split and traffic assignment (CMSTA) model is developed, where a cross-nested logit (CNL)-based multi-mode passenger assignment model addresses route overlapping, and a nested logit (NL)-based mode split model accounts for the hierarchical choices of vehicle type (manual driving or auto driving) and commuting modality (driving alone or shared mobility). Formulated as an equivalent variational inequality (VI) problem in path-flow space with asymmetric link impedance functions, its equivalence is established. A new iterative solution algorithm integrating route-swapping, mode-swapping, and weighted adaptive self-regulating average techniques is developed to efficiently tackle the CMSTA problem. By reformulating the CMSTA as an equivalent nonlinear programming (NLP) problem and taking the multimodal stochastic system optimum (MSSO) as the objective, we further propose a mixed-integer nonlinear program (MINLP) for optimal EL network design.
