However, economically disadvantaged youth have far less OST access compared to their wealthier counterparts. In sprawling, low-density metropolitan areas, a lack of reliable and cost-effective transportation services constitutes a considerable barrier to OST participation for youth from these families. Research on youth travel focuses on school trips and compares active travel modes, such as biking and walking, to motorized modes. However, there is a gap in understanding the travel choices, preferences, and perceptions of underrepresented youth to access OST activities. This study conducted a revealed preference and stated preference survey of underrepresented youth in metropolitan Kansas City, KS-MO, aged 13–18 years old, to capture their travel behavior and interest in utilizing different modal options and evolving technologies in transportation to access OST activities. Five realistic Stated Choice Experiments pivoting the level of travel time and cost for each alternative (i.e., sharing a ride, hailing a ride, renting bikes/scooters, and taking public transit) were conducted. The study used several machine learning (ML) algorithms to predict students’ mode choice preferences at aggregated and individual levels. Among the ML algorithm approaches deployed here, the boosting-based ensemble learning models outperformed the other ML models. The results showed that most students had a low probability of switching from their current mode of transportation across the different choice scenarios, possibly due to a lack of equitable and sustainable transportation options for students to engage in OST activities and uncertainty in the role of evolving technologies in transportation to address this lacking.</p>","PeriodicalId":49419,"journal":{"name":"Transportation","volume":"23 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143847103","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}

We draw on the extensive literature on travel behavior, which has shown that people’s travel behavior is at least in part shaped by the travel barriers they experience. Starting from this basic insight, we define 17 parameters that may provide insight into a person’s relative ease of movement. These ease of movement parameters cover dimensions related to trip frequency and diversity (e.g., overall and in evening hours), transport mode use (e.g., as driver or passenger), travel speed (e.g., for public transport legs), distance (e.g., trip detour ratio), and effort (e.g., ratio between trip legs and out-of-home activities). No single parameter is sufficient to determine whether someone is served well or poorly by the transport system, as behaviors may be the result of choice as well as constraint. However, we argue that jointly the parameters are likely to differentiate well-served from poorly-served people. We apply our approach to data from six GPS-based travel behavior surveys conducted in Israel’s four main metropolitan areas (N = 62,981). We calculate z-scores for all ease of movement parameters, with negative values suggesting mobility problems and positive values relative ease of movement compared to the entire sample. We conduct four known-group analyses, comparing mean z-scores by level of access to a private motorized vehicle, age, gender, and disability. Results are systematically in line with expectations: population segments identified in the literature as experiencing (more severe levels of) transport disadvantage show systematically lower composite mobility scores. These outcomes are particularly striking, considering the short observation period of only one day per respondent. Taken together, these findings provide a first indication that revealed travel behavior patterns can be used to identify population segments poorly served by the transport system and thus to determine both success and failure of the existing transport system. While more research is needed, the approach also holds promise to determine the impacts of transport projects on people’s ease of movement.</p>","PeriodicalId":49419,"journal":{"name":"Transportation","volume":"9 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143847105","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}

Each index is individually optimized within a bi-level optimization framework, enabling a comprehensive assessment of its impact on network performance. Unlike conventional travel time-based optimization, these indices exhibit lower sensitivity to factors such as time-of-day demand variations, as they primarily capture the intrinsic structural properties of the network. Applications to the Sioux Falls and Tehran networks under different peak-hour scenarios demonstrate that incorporating these indices enhances network cohesion, improves accessibility, and promotes sustainable mobility. Notably, closeness centrality consistently delivers superior performance while maintaining computational simplicity, making it a promising metric for future transportation planning. Furthermore, a multi-objective optimization approach was applied to the Tehran network, where the weighting scheme was derived from a distance-based analysis. Interestingly, the results reveal that solving the NDP with a single-objective function based on closeness centrality yields outcomes remarkably close to those obtained from the multi-objective formulation. By integrating these alternative indices, this research advocates for a paradigm shift in network design that extends beyond operational efficiency, fostering more resilient, accessible, and user-centric transportation systems.</p>","PeriodicalId":49419,"journal":{"name":"Transportation","volume":"17 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143847102","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}

Based on mixed logit models and likelihood ratio tests, we find evidence that position does indeed matter: standing close to the door is preferred over other standing positions in the carriage. Regarding COVID-19, we find that crowding costs are lower after the pandemic but cannot reject the hypothesis that this reduction is independent of position.

To this end, a mobility survey was performed in Naples (Italy) where two metro options, comparable with respect to service characteristics and the connections delivered, differ only in the quality standard of the stations. A binomial Hybrid Choice Model with Latent Variables (<i>LVs</i>) was estimated, jointly with a traditional Logit model as a benchmark. Three <i>LVs</i> proved significant and able to model/quantify the relevance of individual attitudes/perceptions (of “comfort”, “art” and “safety”). Estimation results show that users with an average comfort perception are willing to spend up to 15 min/trip (2.67 Euro/trip) more for high-quality service; users with an average art perception are willing to spend more time traveling (9 min/trip or 1.5 Euro/trip).

However, a significant gap exists in understanding user choice behavior between DBS and EBS for metro connectivity. As shared micromobility options, DBS and EBS exhibit more competitive and complementary relationships compared to other transport modes when integrated with metro services. This study aims to bridge this gap by exploring the factors that influence the choice of DBS and EBS as metro connection modes. Taking Kunming—a Chinese city where both modes coexist—as a case study, the study identifies DBS and EBS trips connecting to the metro using operational data analyzed through the K-dimensional tree method (KDTree) along with Kernel Density Estimation analysis (KDE) methods. A Light Gradient Boosting Machine (LightGBM) model analyzes nonlinear effects in both to-metro and from-metro scenarios across four aspects: socioeconomic attributes, travel characteristics, the built environment, and transportation facilities. The results indicate that transportation facilities and the built environment significantly influence DBS and EBS user choices for metro connections, with notable nonlinear effects. For instance, cycling distance significantly influences mode choices. Initially, the probability of selecting EBS increases with cycling distance, then stabilizes. The likelihood of choosing EBS initially decreases and then increases as road non-linear coefficients rise in two modes. These insights deepen our understanding of DBS and EBS user choices for metro connections, improving the integration of these modes for first/last-mile journeys.</p>","PeriodicalId":49419,"journal":{"name":"Transportation","volume":"6 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143814181","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}

Transit potential needs indices were computed using scaling and exploratory factor analysis. Then, a spatial overlap analysis evaluated where the most significant gaps exist. Results showed that job access by transit decreases with increasing levels of education. This was explained by the location of stationary jobs in specific central corridors for the highly educated and a relative increase in educational outcomes of the population living toward the outskirts (increasing spatial mismatch).

In this study, we aim to improve our understanding of the trips made to the University of Sydney campuses, one of the largest universities in Australia, through investigation of how individuals (namely, staff and students) choose to study/work from home and their modes of transport used to go to campus on different days of the week. We have collected three sets of data: one in 2022 and two in 2023, using a survey answered by both staff and students. A hybrid logit model including latent variables is estimated to understand the motivations and main drivers to work/study from home and to choose different modes of transport when attending campus. The results indicate that while travel times and costs/fare are important, they are not the primary factors influencing travel behaviour and mode choices. One key factor was whether staff and students worked or studied from home and campus on the same day, with these individuals more likely to use active transport modes, which is also associated with living closer to campus. Students living farther from campus tend to attend more frequently and primarily use public transport.

Recent advancements in city-scale transport modelling enable virtual testing of such interventions. However, the application of agent- and activity-based models for large-scale cycling simulations has been constrained by data and complexity. In this study, we developed a city-scale agent-based simulation model for Greater Melbourne to evaluate changes in travel mode share from cycling infrastructure modifications. We clustered bicycle riders into five demographic groups: Maverick Males, Motivated Adults, Conscientious Commuters, Young Sprinters, and Relaxed Cruisers, estimating mode choice parameters for each group. Using aggregated smartphone application data, we developed a cycling trip routing methodology to incorporate road infrastructure impacts. Results indicated that travel time significantly influences mode choice across all clusters. Cycling infrastructure was crucial for four clusters, and travel cost influenced four clusters. The calibrated model assessed the potential impact of fully implementing Greater Melbourne’s strategic cycling corridors, a network of key cycling routes. Simulations suggested an initial 30% increase in cycling use, raising the mode share to approximately 2.6%, indicating a modest overall impact. Further analysis showed that even with full implementation, on average about half of the lengths of the routed bikeable trips would still occur on roads without any cycling infrastructure. This underscores the need to improve infrastructure on both major corridors and minor roads, and to complement these improvements with behavioural interventions.</p>","PeriodicalId":49419,"journal":{"name":"Transportation","volume":"12 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143766928","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}
