A shortcoming of the current operational methods for rural highways is the limited consideration of quality of service for non-motorized users. This research aims to determine which variables are most relevant to bicyclists cycling (or not) on rural highways and their operational cycling preferences. An online survey collected 982 responses from individuals who cycle on rural highways in the United States. Eight choice tasks were presented with six factors: pavement quality, automobile traffic level, posted speed limit, roadside design, context class, and grade. These factors were obtained from a preliminary survey targeting highway analysis and design practitioners. The results of a mixed-logit model analysis suggest that the presence of a shoulder and its width are the most critical factors to a cyclist’s perceived quality of service on a rural highway. We found that the difference between rural-town and suburban contexts was minor compared to rural contexts. The results demonstrate how cyclist types influence their overall willingness to cycle and their preferences for scenario-specific attributes. This opens the discussion to include different sets of thresholds to assess service levels as a function of cyclist type, following the level of traffic stress approach, and separate perception models by cyclist type. These results should inform recommendations for future research on improving existing evaluations related to bicycling on rural highways.</p>","PeriodicalId":49419,"journal":{"name":"Transportation","volume":"25 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144123023","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}

The proposed approach accounts for sequential patterns, activity transitions, and cross-day similarities, providing deeper insights into travel behavior beyond traditional statistical methods. Analyzing weekly activity patterns from this longitudinal data revealed significant insights into travel behavior, including distinct work and non-work patterns across the week. For working groups, shorter work durations on Fridays were observed, and the weekly work duration for teleworkers was found to be lower than that of workplace workers. Although the detailed exploration of weekly activity and time-use patterns provides valuable policy insights, this research primarily focuses on advancing activity-based travel demand modeling by introducing a mathematically robust approach to capturing sequential and temporal activity patterns.</p>","PeriodicalId":49419,"journal":{"name":"Transportation","volume":"120 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144066650","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 find that while the sign of the preferences is the same for all cyclist types and is consistent with previous findings from the literature on cycling infrastructure preferences, e-bikers and especially s-pedelec riders do have a lower willingness to pay (WTP) for improvements of cycling infrastructure and are more comfortable in sharing the street space with cars. E-bikers do have similar preferences as conventional cyclists for the most important safety-related elements, i.e. for cycling paths instead of cycling lanes on main streets and “cycling-street” designation of neighborhood streets. For these same features, the WTP decreases with cycling frequency, less frequent cyclists valuing such elements more. At the same time, those who cycle less have a lower WTP for car traffic related features. </p>","PeriodicalId":49419,"journal":{"name":"Transportation","volume":"4 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144066702","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}

Yet, its potential benefits particularly hinge on penetration and utilization rates. To date, few studies have explored user acceptance of systems that integrate passenger and freight flows. In this context, a research gap that is particularly evident pertains to the user acceptance of different concepts within autonomous combined transport. Extending the unified theory of acceptance and use of technology (UTAUT2), this paper examines the effects of six psychological constructs on the behavioral intention to use an autonomous combined transport system. Surveying 1040 respondents from Germany, two distinct combined transport concepts—scheduled and on-demand—were examined to identify key acceptance factors and operational peculiarities. Results from structural equation modelling show that the acceptance of autonomous combined transport systems depends on both, the operational concept as well as the purpose of use, with socio-demographic characteristics featuring different indirect effects per concept. Moreover, we find that performance expectancy, effort expectancy, price value, personal attitude, and trust are significant predictors of behavioral intention across both concepts, while the average order frequency of a potential user has a negative indirect impact on behavioral intention. Results show that an extended UTAUT2 model can conceptualize factors influencing autonomous combined transport acceptance, emphasizing the importance of investigating a user’s behavioral intention based on the specific operational concept.</p>","PeriodicalId":49419,"journal":{"name":"Transportation","volume":"9 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144066649","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}

There is a strong need to integrate equity considerations into transit planning, while respecting the long-term financial sustainability of the public transport system.

By changing the recipient of benefits or penalties over time, the multi-period allocation perspective allows the model to improve the tradeoff between efficiency and equity. We use Pareto-front analysis to demonstrate the improved tradeoffs between efficiency and equity of the EoT approach, then show through numerical experiments that the EoT framework is able to achieve better or equal solutions than its single period counterpart in all instances. We propose a customized matheuristic combining pattern generation and scheduling to solve larger instances. Numerical experiments show that the heuristic is on average 99.03% faster than the exact method for instances that return a solution.

However, how the perceived ability to travel, i.e., ease of travel (EoT), influences travel satisfaction has not been analysed in a comprehensive way. In this study, we will analyse how EoT, which is comprised of travel motivation, travel skills, travel options and travel quality, impacts satisfaction with travel to campus of 2593 students and staff members of University College London (UCL). One-way ANOVAs show that respondents with high levels of EoT are more satisfied with their trips to campus compared to those with lower EoT levels. Based on linear regressions (per mode and all modes combined), we found that all EoT elements seem to positively affect travel satisfaction, even after controlling for socio-demographics and trip characteristics. This indicates that EoT may be regarded as an important predictor of travel satisfaction. Apart from EoT, also age, mode choice, weather conditions and levels of crowding and congestion were found to significantly impact travel satisfaction. Somewhat surprisingly, effects of travelling alone, trip duration, and travel disabilities on travel satisfaction – which were often found in existing studies – were weak, suggesting that these effects may be partly explained/moderated by variations in EoT elements. In order to make public transport and active travel trips more satisfying, we recommend policy makers to focus on (1) improving the quality of public transport services and active travel infrastructure, and (2) helping people to improve their skills required to easily walk, cycle or use public transport.</p>","PeriodicalId":49419,"journal":{"name":"Transportation","volume":"123 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143940113","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}

Previous studies on ATP variabilities are often limited to a short period and cannot comprehensively reflect the interpersonal and intrapersonal variabilities. In addition, the traditional clustering methods lack sufficient learning ability for high-dimensional feature space, and clustering variables are simple aggregated indicators. In this study, we propose an ATP inference algorithm that reconstructs multi-week individuals’ discrete trips into an ATP, and the ATP is modeled as stochastic process. Various indicators regarding the standard deviation (SD) of travel time, the SD of number of trips, and the entropy of ATPs are applied, and the entropy rate of ATPs is explicitly considered to take account of the order of activity/travel choices. The intrapersonal variability of ATPs is obtained through these indicators. The interpersonal variability of ATPs is investigated by dividing people into groups based on their ATPs through a deep embedded clustering approach, which refers to a deep neural network formed by integrating the stacked denoising autoencoder with the basic clustering algorithm. The proposed deep embedded clustering is tested using massive smart card data collected from the metro system in Nanjing, China.

The model integrates objectives of maximizing trip entropy to generate diverse solutions alongside minimizing costs. Demand and supply parameters are modeled using fuzzy logic to incorporate the inherent uncertainty of these data. A recent extension of the Markowitz investment model was adapted to account for cost variability. The primary goal is to equip transportation planners with a decision-making tool that incorporates uncertainty. A comparative analysis of different objectives is conducted to assess the effects of risk on outcomes. The multi-criteria TOPSIS method was utilized as a robust tool to select solutions for this multi-objective problem. Results reveal that solutions with high entropy and variability balance risk and flexibility, while those minimizing variance offer more stable solutions with lower risk. Consistently minimizing total cost resulted in the lowest costs, but at the same time, it led to the highest risk. The membership level showed that maximizing entropy and minimizing variance generated similar compliance levels, with lower variability in the case of entropy. Cost minimization resulted in lower compliance, indicating a trade-off between cost and effectiveness in the transportation network. The research demonstrates that prioritizing risk minimization enhances the average membership level compared to approaches focused on cost minimization or entropy maximization. By effectively managing and reducing uncertainty in transportation networks, the developed model serves as a tool for managing and reducing uncertainty in a transportation network, enhancing resilience. Furthermore, its adaptability offers potential applications across diverse aspects of logistics and industry, providing a framework for designing more robust, adaptive, and effective operational strategies.</p>","PeriodicalId":49419,"journal":{"name":"Transportation","volume":"33 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143853296","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}
