Specifically, this study 1) generates large-scale synthetic commuting trip data for 374 urban areas, 2) employs an agent-based modeling framework to simulate the operations of SAV fleets serving commuters in these areas, and 3) develops models to explain the variations of fleet performances across study areas. The main objectives of this study are to compare the performances of SAVs serving commuting trips across urban areas and to identify the correlates of SAV fleet performances related to regional road networks and travel demand characteristics. This study generated 30 million synthetic commuting trips for 374 small and medium-sized urban areas based on the Census' latest Longitudinal Employer-Household Dynamics (LEHD) data and the National Household Travel Survey (NHTS) data. Based on the agent-based modeling results, SAV fleet performances across 374 urban areas were analyzed. Key performance measures include the average number of trips per SAV vehicle for fleet efficiency and the percentage of empty vehicle miles traveled (VMT) for extra operating costs. Results showed significant spatial variations in SAV fleet performances across 374 urban areas. The results highlighted urban areas that either outperform or underperform other areas. For example, Great Falls MT, is associated with the highest fleet efficiency, and Fort Walton Beach-Navarre-Wright, FL, has the lowest percentage of empty VMT. Through statistical modeling, this study identified significant correlates of SAV fleet performance, which are significantly related to factors of road network properties and travel demand characteristics. A larger, denser, and more connected network is associated with greater fleet efficiency and reduced operating cost, while a network with a local clustering tendency may lead to decreased fleet efficiency and increased operating cost. Areas with denser trips or longer trips are associated with lower fleet efficiency and decreased operating costs. More modeling results are discussed in the paper, providing insights into how different local road network characteristics and travel patterns influence the operation of SAVs. These results help to identify strategies for tailoring SAV services to the unique needs of different regions. This study complements the literature on shared mobility and automation research currently centered on great metropolitan areas. The research findings are intended to serve as the basis for future discussions regarding opportunities and challenges of deploying emerging mobility services in small and medium-sized areas. The large-scale synthetic commuting data generated in this study are valuable for researchers and agencies to develop advanced travel and mobility models and to further explore the potential of deploying emergi","PeriodicalId":48413,"journal":{"name":"Journal of Transport Geography","volume":"127 ","pages":"Article 104302"},"PeriodicalIF":5.7,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144147524","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 this approach captures service resilience through train rescheduling, flexible stops and short turnaround times enabled by redundant tracks, it often overlooks the critical role of track layout in train operations during disruptions. Moreover, it may fail to accurately reflect system behavior, as operators might close rail sections to maintain service efficiency, preventing turnback operations. This article integrates track layout into vulnerability envelope analysis for urban rail transit networks.

However, data-driven studies on these services, particularly those using spatial-temporal analysis, remain complex and underexplored. This study examines the intricate relationship between ride-pooling and metro services through a large-scale dataset from Suzhou, China, focusing on identifying cooperative and competitive dynamics between the two modes, classifying multimodal trips that include both ride-pooling and metro services, and uncovering spatial-temporal patterns within these interactions. The analytical framework incorporates joint methods such as time-sequence analysis, non-negative matrix factorization, and metro passenger origin-destination matrix inference to achieve the study's objectives. Findings reveal that 4.26 % of all ride-hailing trips were pooled rides, while multimodal trips involving transfers between ride-pooling and mass rapid transit accounted for 13.5 % of total trips, offering economic benefits for users. These multimodal trips primarily cater to commuting demands and exhibit distinct, imbalanced peak-hour usage patterns. Spatial analysis indicates that the majority of these trips occur in suburban and outskirt areas, where mass rapid transit coverage is limited and correlates strongly with “industrial” land use. The distribution of corresponding metro trips shows similar spatial patterns.

A case study is performed in Stockholm, Sweden. Using ST-DBSCAN, travel patterns are mined from transit smartcard data of frequent transit users to build representative trajectories. Grocery store accessibility is defined as the number of stores reachable within a 15-walk of anchors along individual trajectories. Results show residents of the dense, walkable city center have high home-based accessibility, but fewer affordable stores. Considering mobility, individuals living in rural or suburban areas with high transit connectivity observe large, positive accessibility increases. However, those living in areas with poor transit connectivity observe marginal accessibility improvements. Residents of the city center also observe marginal accessibility improvements as they already live in resource-rich areas. The trajectory-based accessibility measure can identify areas requiring accessibility improvements or evaluate policy effects (e.g., changes in transit routes) on accessibility.</div></div>","PeriodicalId":48413,"journal":{"name":"Journal of Transport Geography","volume":"127 ","pages":"Article 104283"},"PeriodicalIF":5.7,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144115119","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}

A scoping review of peer-reviewed scientific literature and grey literature was conducted between January and March 2024. We screened five major databases (PubMed, Web of Science, Scopus, ProQuest, and Google Scholar) for studies reporting barriers and facilitators affecting older adults' access to mobility in LMICs. Using deductive content analysis and the Theoretical Domains Framework (TDF), barriers and facilitators were categorized into behavioral determinant domains spanning four overarching categories: individual, socioeconomic, place-based, and institutional. Forty-four articles from Asia, Africa, and Latin America met the inclusion criteria and were retained for data extraction. Safety concerns, exacerbated by inadequate infrastructure and unsafe road user behavior, represent significant barriers, while gender norms specifically restrict older women's mobility. Conversely, key facilitators include familial support and intergenerational solidarity, subsidized transport, and specific government interventions. Older adults' mobility in urban areas of LMICs is affected by safety concerns, especially for women, and a lack of appropriate infrastructure and reliable public transportation options. These barriers result in limited outdoor mobilities, potentially leading to social isolation and exclusion. These challenges can be overcome through specific interventions that promote more affordable, reliable, and safer public transportation and improved walking options.</div></div>","PeriodicalId":48413,"journal":{"name":"Journal of Transport Geography","volume":"127 ","pages":"Article 104289"},"PeriodicalIF":5.7,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144071027","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}
