However, current approaches face various challenges in reliably obtaining contextual attributes. Therefore, investigating the capability of combining contextual attributes collected from different time-geographic approaches is essential for promoting data quality of contextual attributes but missing in previous studies. To address this issue, this study employed data collected in a cross-sectional survey in Hong Kong to cross-validate activity-travel diaries and GPS-derived trajectories, two primary data collection approaches in transport geography studies. We recruited 782 participants in four representative communities through a stratified sampling scheme. Participants were asked to fill out activity-travel diaries and carry a GPS-equipped smartphone on a working day and a non-working day, respectively. Staying/moving events were identified from the GPS-derived trajectories using a spatiotemporal clustering algorithm while activity-travel records were manually aggregated as activity-travel events, which were then matched with the corresponding staying/moving events. Rigorous preprocessing revealed that about 90 % of the 8500 detected events matched well across the two approaches, and about 76 % of them are one-to-one matched events. Yet, the matching rate shows significant disparities between different socio-demographic groups and geographic and activity contexts. The findings indicate that GPS-derived events can mitigate recall biases in the temporality of activity/travel, while diary-based events provide enriched contextual attributes unavailable from GPS data alone. Our study systematically articulates the (mis)match between different approaches for collecting contextual attributes, and it provides essential insights and protocols for a broad scope of environmental and transport studies that need elaborate and comprehensive contextual information.</div></div>","PeriodicalId":48413,"journal":{"name":"Journal of Transport Geography","volume":"126 ","pages":"Article 104239"},"PeriodicalIF":5.7,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143828575","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}

Through semi-structured interviews with 27 male and 24 female stakeholders, we used purposive text analysis (PTA) and qualitative system dynamics modeling to map mental models and identify key drivers of gendered perceptions of transportation security. The PTA revealed 31 factors influencing safety perceptions across five dimensions: State, Transport System, Bus Drivers, Social Issues, and User Behavior, along with 646 causal connections—409 and 237 of which related to public transportation challenges and solutions, respectively. Comparative analysis of the models for male and female stakeholders showed that while males mainly associate insecurity with crime, females face a broader array of concerns, including harassment, distrust, and inadequate infrastructure. The findings highlight how poor infrastructure, limited surveillance, and negligent driver behavior disproportionately affect female passengers' perceptions of safety. These results call for targeted interventions, including enhanced surveillance, better infrastructure, and gender-sensitive policies to improve security. To address these challenges, a systems approach is needed, incorporating both urban design improvements and community-based initiatives—such as alert systems and driver training—that reduce reliance on private security and create a more inclusive, accessible public transportation environment.</div></div>","PeriodicalId":48413,"journal":{"name":"Journal of Transport Geography","volume":"126 ","pages":"Article 104221"},"PeriodicalIF":5.7,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143834897","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}

Building upon network centrality measures and incorporating concepts from transportation and geography studies, the proposed index integrates spatial competition for limited-capacity opportunities into a directed, weighted network model. The PA index accounts for both supply (e.g., employment opportunities) and demand (e.g., population) attributes, and their spatial interaction within a global analysis or a local one (with a predefined catchment radius). To demonstrate the PA index's properties and practical relevance, we apply it to two medium-sized Brazilian cities, analyzing accessibility to formal employment opportunities. We conducted four experiments: an unweighted analysis, a supply-weighted analysis, a competition-based analysis with both supply and demand weights, and a local accessibility analysis using a 1600-m radius. A fifth experiment compares the PA index to Reach centrality, a non-competitive network-based accessibility measure. Results reveal how variations in street network configuration influence accessibility outcomes and inequality patterns, captured using the Palma Ratio. The PA index distinguishes local from global accessibility more effectively than the Reach index and better reveals how competition and proximity affect opportunity access. The method's flexibility allows for multiscalar analysis, integration of social attributes, and scenario simulations, supporting planning applications aimed at equitable access to services.

The analysis examined road network composite vulnerability index changes under different intentional attack strategies (e.g., targeting nodes with the highest or lowest composite vulnerability index first) and user response behaviors (comprehensive information availability and limited information acquisition). The results indicate that targeting nodes with the highest vulnerability causes 2.5 times more overall vulnerability than targeting nodes with the lowest vulnerability. Under comprehensive information availability (CIA) conditions, the road network's composite vulnerability index decreases by approximately 0.02 compared to limited information availability (LIA) conditions.

Existing research has explored these factors; however, significant gaps remain as the approach overlooks explicit and implicit nuanced user experiences, especially those of car users. The scaler and relative influence of factors impacting first-mile and last-mile access, how car users perceive these issues and their impact on car usage are gaps to be explored.

This study employs a framework to address this gap, integrating Exploratory Factor Analysis, Importance Performance Analysis and paired sample <em>t</em>-test to explore the interplay of first and last-mile factors. Findings indicate that safety while accessing bus stops, security at bus stops, pedestrian pathways or infrastructure, and proximity of bus stops, among other factors, are critical for improving overall satisfaction with first and last-mile connectivity for car users using public transport.

We estimate charging demands by analyzing EV usage patterns, charging/discharging plans, charging station availability, and user preferences such as routing and driver anxiety. The study explores a new EV charging optimization scenario considering charging costs, traffic, travel time, and setup time. A vital aspect of the proposed model is its ability to facilitate bidirectional energy flow between EVs and the power grid. This strategy enhances grid stability and facilitates efficient energy management, with charging stations actively participating in load balancing, peak shaving, and grid stabilization during a cyberattack. Furthermore, we formulate a network interdiction problem that strategically removes specific links in the power network to prevent the spread of a cyberattack. The effectiveness of the proposed approach is evaluated through five case studies. The findings suggest that the proposed hybrid planning solution (Case 5) is the most effective strategy.

It is widely shown that a safer, reliable, and comfortable transport service fosters greater trust in the transport system and leaves users with a positive perception of ease of movement within a geographical area. Moreover, the quality of public transport services has long been recognized as a crucial factor in shaping perception of accessibility to a place, potentially expanding the catchment area by attracting a larger number of users. In designing new terminals, many planners worldwide specifically focus on hedonic (aesthetic) aspects, also influencing the user's quality perception. Unlike rail stations, bus stations have had little attention with respect to aesthetic quality and passenger services, even if many studies have highlighted the significant impact that the design, services, and amenities of bus waiting areas have on user satisfaction. This study focuses on the hedonic value of a bus station and estimates users' willingness to pay (WTP) for enhanced station quality. The research targets are university students (aged 18–25) traveling on extra-urban routes, involving three major Italian cities: Milan, Rome, and Naples. Using a Discrete Choice Experiment (DCE) conducted through a Virtual Reality (VR) immersive experience, this study explores users' willingness to switch from a conventional bus station to a newly designed high-quality one, assessed in terms of both architectural standards (i.e. the “beauty”) and the functional quality (i.e. passenger's services offered, like restaurant, bar, free Wi-Fi, shops, comfortable waiting room, e-ticketing devices). Analyzing various cost and travel time SP scenarios, the model results shows that the average Italian student is willing to pay an additional €3.11 per trip (equivalent to 25 % of the actual average trip cost) or extend their travel time by up to 20.9 min per trip (26 % of the average actual travel time) to experience a superior bus station instead of a traditional one. The practical implications of this study are clear for urban planners, policymakers, and transport authorities: prioritizing investments in high-quality stations can significantly improve passenger satisfaction and promote greater use of public transport.</div></div>","PeriodicalId":48413,"journal":{"name":"Journal of Transport Geography","volume":"126 ","pages":"Article 104235"},"PeriodicalIF":5.7,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143817051","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}
