Personal technologies, particularly smartphones, have become integral to tackling these challenges but come with their own caveats around user acceptance and engagement. The current paper investigates these issues in the context of a longitudinal study of interventions designed to encourage use of public transport and increase associated physical activity in Tasmania, Australia. The study comprised multiple waves of data collection over a seven-month period in which travel data were collected using a smartphone app supplemented with user experience surveys. Attrition is lower for older participants, those engaging with the app more, and those responding to the research/environmental/health messaging of the survey as well as the potential for financial gain. App usage is lower among older participants while app engagement is stronger for males, those recording less travel and those indicating environmental reasons as a motivator for completing the study. Experiences with the app are mixed, participants report positive sentiments about the ease of use, hedonic motivation, and help in recalling travel; however, concerns are raised over the accuracy of trip recording, the associated burden of correcting trips, and reductions in smartphone battery-life.

Many practitioners and policymakers turn to well-established active mobility cultures, such as the Netherlands, to identify best planning practices. However, walking and cycling rates remain low, and arguments are made that besides built environment characteristics, cultural contexts and social norms are also important in encouraging walking and cycling. While travel behaviour is found to be significantly influenced by socialisation factors (e.g. cultural and social norms), the processes of influence are mediated through an intermediate step of past behaviour. In order to understand the role of socialisation factors in changes towards active travel behaviour a whole view of an individual’s life is therefore needed. This study addresses this research gap by investigating the role of long-term socialisation factors and built environment characteristics in the active travel behaviour of high-income immigrants (e.g. expats) living in the Netherlands, using a qualitative, biographical approach. The findings demonstrate that walking and cycling behaviour can significantly change due to the presence of facilitating factors in the built environment, supportive social networks and the normalisation of walking and cycling as modes of transport. People who have grown up and lived in places with little tradition of walking and cycling, can change their travel behaviour if the environment, both physical and social, makes walking and cycling a viable and attractive option to travel instead of using motorised transportation.</p>","PeriodicalId":49419,"journal":{"name":"Transportation","volume":"36 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143734021","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}

Expectations that the peak would’flatten out’—resulting from the pandemic and working from home—are not supported in the bus case and only partially in the case of rail. Following very large increases in public expenditure to enable continuation of services, that in the bus industry has returned to a broadly pre-pandemic level, while that for rail remains substantially higher. Whilst the pre-Covid cost structures result in a higher degree of short-run escapability for bus, it is also the case that bus has proven to be more flexible in the medium-term, notably in returning to the level of bus-kilometres per member of staff found pre-Covid.

While several works explored the potential of this technology for modelling mode choice, lower attention is given to route choice, especially in public transport. In this work, we propose a deep learning model designed specifically for route choice in public transport. The model can estimate a nonlinear utility function, allowing complex interactions among the variables; it can easily include non-alternative specific variables, such as weather or socio-demographic information. Moreover, compared to the traditional choice models, it numerically outperforms the Path Size Logit Model in prediction performance, and does not require pre-specification of the model by an experienced human modeler. These properties are particularly useful for route choice analyses, to capture possible heterogeneities or complex behavior, which are difficult to model a priori. We evaluated the interpretability of the model observing the marginal rates of substitution and applying Accumulated Local Effects, showing meaningful effects of the variables on the probability to choose an alternative. We tested the proposed model on a large-scale dataset based on GPS tracking. We considered both synthetic choices, to demonstrate the model properties, and real choices, to evaluate the model in practice. The results showed moderately better performance of the deep learning model compared to the Path Size Logit, confirming the possibility of using it for modeling and predicting route choice.</p>","PeriodicalId":49419,"journal":{"name":"Transportation","volume":"25 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143583014","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}

Therefore, this study investigated the forms of multimodality and their relationship with individual travel contexts considering new trends in the urban mobility sector. In the identification of modality styles, a broader and more detailed set of transport modes was considered; and in the definition of individual travel contexts, a series of factors related to the availability and accessibility of transport options and mobility services were considered. Using latent class analysis, this study identified five modality styles including three forms of multimodality that have not been found in previous research. Distinct forms of public transport (bus, tram, metro, and train) were found to be used in conjunction with other transport modes in different ways, leading to different forms of multimodality. Mopeds and motorcycles, rarely considered in previous research, were found to be the primary travel mode for a small group of people. In addition, weighted multinomial logit regression was used to assess the association between individual travel contexts and modality styles. The results indicate that new mobility services, such as (e-)bike-sharing, have the potential to promote more sustainable forms of multimodality that combine active modes with public transport.</p>","PeriodicalId":49419,"journal":{"name":"Transportation","volume":"38 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143583015","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}

This study aims to identify cruising speed from GPS data and investigate how it varies with contextual and personal factors. We evaluate six algorithms to extract cruising events from cycling GPS travel data: three time series clustering methods to identify steady-state events, in combination with two labeling methods to identify which events represent cruising. The best-performing algorithm uses Toeplitz Inverse Covariance-Based Clustering and identifies cruising events based on a decision tree heuristic. The average cruising speed of 21.53 km/hr is significantly higher than the overall average speed of 19.95 km/hr. Cruising speeds are higher for commute trips, longer trips, e-cyclists, ‘Dedicated’ cyclists, and men. Regarding route factors, cruising speeds are higher in locations with lower grade, more greenery, on-street cycling facilities, high motor vehicle volume, no traffic controls, and lower relative crash risk. Distinguishing cruising events within cycling trajectory data is necessary to avoid underestimating the behavioural sensitivity of cyclists to factors such as road grade, facility type, relative crash risk, trip purpose, gender, and bicycle motorization.</p>","PeriodicalId":49419,"journal":{"name":"Transportation","volume":"84 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143526051","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}

By broadening the scope to include these diverse modes, our research offers a comprehensive analysis of how urban rail transit systems contribute to pollution reduction in Chinese cities. Utilizing panel data from 2011 to 2023, we investigate the effects of rail transit development on air quality, focusing on two primary mechanisms: replacing taxi usage and lowering per capita traffic energy consumption. Our empirical findings, derived from a Difference-in-Differences approach, reveal that the expansion of urban rail transit significantly reduces urban pollution levels.
