A sample of 339 responses collected via a stated preference survey is used for choice model estimation. The results reveal that scheme attributes can increase participation propensity, including three cobenefits (species extinction reduction, air pollution reduction, and premature death reduction), scheme costs, and government certification. The positive effect of attitudes toward carbon offsets on scheme participation is significant for tourism travelers. However, attitudes and altruism do not influence the scheme participation of business travelers. Business travelers’ willingness-to-pay values for scheme attributes are greater than those of tourism travelers.

In response to the ongoing threat from missiles, drones, and artillery, we developed a unique methodology to evaluate the “passafeguard” level at various transit stops across the city. Using PTV VISUM software, we conducted spatial–temporal analyses that consider different types of threats, directly impacting the time available for passengers to reach safety. Isochrones were constructed for three time intervals (2,<!--> <!-->5, and 15 min) based on threat types (e.g., Ballistic, S‑300; Cruise missile; Strike Drones) to identify shelter accessibility. Our system analysis includes a variety of shelter types: metro stations, basements, and specially designed concrete shelters at transit stops. We assessed passenger safety in distinct Transport Analysis Zones (TAZs) across different scenarios: pre-invasion, invasion, power available, and blackout (temporary routes), which affect the availability of electric transport options. Key metrics calculated include density by shelter types in proximity to the stops, coverage area of shelters, and stops lacking shelter proximity. This study highlights current shortcomings in Kharkiv’s public transport stops accessibility to shelters and provides a method to assess it across other cities facing similar challenges. It leads to specific recommendations for optimising shelter locations to improve accessibility. The quadrant-based classification system enables diagnosis of mismatched infrastructure zones (e.g., high-transit but low-shelter coverage), informing targeted interventions. By conceptualising transit stops as critical nodes in civil protection planning, the passafeguard concept offers a transferable methodology for enhancing urban resilience. Research provides broader discourse on transportation infrastructure safety, emergency response in urban conflict environments, urban mobility adaptive protection strategies and passenger safety, offering data-driven insights and actionable recommendations for policy-makers and urban planners globally.</div></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":"201 ","pages":"Article 104669"},"PeriodicalIF":6.8,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145120411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we estimate a mixed logit model to examine the factors influencing the choice between pooled and solo ridehailing (e.g., UberX), using a dataset collected through <em>rMove</em>, an in-app survey and GPS data collection tool, which captures residents’ travel behaviors across three metropolitan regions in California.

Frequent ridehailing users are more inclined to share rides, whereas employer-paid work trips are less likely to be pooled. Trips originating in high-density areas are also more likely to be pooled. Furthermore, we find a positive relationship between the use of public/active modes and the likelihood of pooling, highlighting both the risk of competition (and substitution) among these modes and an openness to multimodal travel among certain groups.

This study introduces a novel inclusive TOD (iTOD) framework that explicitly integrates affordability into performance assessment. Combining open and big data with official statistics, we measure citywide location affordability indices for two prominent social groups—homebuyers and renters—and incorporate them into an inclusivity evaluation of 302 TOD sites in Shenzhen, China. Using Data Envelopment Analysis, we find that even generally well-developed sites often underperform in terms of inclusivity, with mean iTOD scores only ranging from 0.22 to 0.71 (out of 1)—indicating large potential for improvement. Clustering analysis identifies 20.5% of sites as considerably low-performing iTOD. Spatial regression reveals workforce housing availability as a determinant of inclusivity in some contexts. The findings underscore the need to incorporate affordability and inclusionary housing provision into TOD planning to systematically reflect transit investment effectiveness, ultimately aligning it with equitable urban development.

Gaining insight into the determinants of residents’ green travel preferences is crucial for its successful implementation. Existing research tends to emphasize the direct influence of personal traits, emotions, and pre-existing perceptions on green travel preferences. However, it frequently overlooks the critical interactive process whereby social influences shape individual perceptions and comprehension of green travel options, thereby obscuring a critical mechanism underlying travel preferences. This paper integrates Social Influence Theory and Goal-Framing Theory to propose an expanded Stimulus-Organism-Response model, examining the effects of social influences, specifically including government policy, interpersonal influence, bandwagon effect, and imitation effect on residents’ green travel preferences. The paper further incorporates the moderating effect of travel purpose and companionship into the modeling framework. The model was empirically specified using the SEM model and survey data from 1,153 Chinese respondents. Our findings reveal that government policy, interpersonal influence, bandwagon effect, and imitation effect significantly shape residents’ green travel preferences. Moreover, the paper uncovers that gain, hedonic, and normative goal frames mediate the relationship between social influence and green travel preferences. The moderating effect of residents’ travel purpose and companionship is also confirmed in our models. Drawing on these insights, this paper suggests differentiated and multi-channel policy improvements, enabling governments to formulate compelling strategies to enhance urban residents’ green travel willingness.</div></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":"201 ","pages":"Article 104681"},"PeriodicalIF":6.8,"publicationDate":"2025-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145099418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we aim to examine ride-hailing usage among different income groups, specifically among above and below the poverty line communities, to identify potential differences in the adoption of ride-hailing services across both population segments. This paper investigates the adoption and frequency of use for RH MC and RH CAR in the Indonesian context. We conducted an analysis using primary data collected in Yogyakarta Province, Indonesia using binary logistic and random effect ordered logistic panel models, both before and during the COVID-19 pandemic. The results indicate that those living in poverty is less inclined to use ride-hailing services, and even when they do, their usage frequency is lower compared to the middle-high-income group. In general, our findings indicate that ride-hailing adopters are more frequently women, middle-young people, having middle-higher income and residents of urban areas. Based on the frequency of ride-hailing use, we found that RH CAR is commonly utilized by higher-income groups.

An Extreme Gradient Boosting (XGBoost) model was employed to elucidate the relationships between travel choice shifts and a set of explanatory variables, including socio-demographic attributes, travel characteristics, perceived service quality at the airport, and delay scenario features. The results show that socio-demographic attributes (e.g., <em>work type</em>, <em>age</em>) and travel characteristics (e.g., <em>ticket price</em>) hold higher relative importance in interpreting travel behavioral intentions. It is therefore necessary to implement differentiated service strategies tailored to passenger groups with different behavioral intentions. Also, findings reveal that the spatial variable matters in trip cancellation and highlight the importance of expanding high-speed railway as an alternative during flight disruptions in underserved regions. By identifying key determinants and ranking their importance in interpreting passenger behavior changes via machine learning instead of traditional econometric models, this study advances disruption management by offering a practical framework for user profiling-driven service strategies against flight delays. It further informs the airport/airline operators in optimizing resource allocation by implementing anticipatory and differentiated policy interventions towards higher operational resilience in preparation for future disruptions.
