{"title":"Examining the determinants of microtransit use and ridesharing based on trip microdata","authors":"Subid Ghimire,&nbsp;Eleni Bardaka","doi":"10.1016/j.tranpol.2025.07.006","DOIUrl":"10.1016/j.tranpol.2025.07.006","url":null,"abstract":"<div><div>Microtransit is a technology-driven public transportation service that accommodates on-demand trip requests and dynamically adjusts its routing based on real-time origin–destination patterns. It provides shared rides with flexible pick-up and drop-off locations and incorporates trip scheduling and fare payment in a smartphone application. Although many jurisdictions in North America have initiated microtransit pilots in recent years, our understanding of these systems remains limited due to the lack of empirical research. This study identifies a methodological framework to investigate the neighborhood sociodemographic, built environment, and other spatial and temporal attributes associated with higher public microtransit use based on trip microdata. As microtransit demand tends to be sparse, resulting in excess zeros in the dependent variable, hurdle negative binomial models are selected as a suitable approach for explaining microtransit passenger pick-ups and drop-offs at a small spatiotemporal resolution. This research also empirically explores the factors significantly influencing ridesharing in public microtransit. Although microtransit vehicles are designed to serve multiple passengers simultaneously, a substantial portion of microtransit trips is single-passenger in practice. A binary logit model is estimated to identify how system-level and local microtransit demand, trip characteristics, and the built environment contribute to the probability of a microtransit trip being shared with another booking. The microtransit system with the highest ridership in North Carolina, operating in the City of Wilson—a community with a large transit-dependent population—serves as our empirical example. Our findings indicate that neighborhoods with lower-income, carless, African American, and younger populations generate greater demand for microtransit. We also find that a larger female population is associated with more microtransit trips, potentially because women are less likely to have a driver’s license or access to personal vehicles, especially in vehicle-deficit households. On average, the likelihood of ridesharing increases for longer trips and when the service experiences high demand but decreases for trips that require a wheelchair-accessible vehicle. Urban areas and local employment and commercial centers are associated with more trips as well as a higher probability of ridesharing.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"172 ","pages":"Article 103725"},"PeriodicalIF":6.3,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145010548","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 oversight can be attributed to the difficulties of applying large-scale spatial data with sufficient precision to accurately identify ridership associated with single entrances or exits. In this study, we used a new type of Location Based Services (LBS) data, the commuter Origin-Destination (OD) data, to calculate Entrance/Exit Ridership (EER) in Xiamen, China. Using the Ordinary Least Squares (OLS) model, and the Random Forest (RF) model with the Shapley Additive exPlanations (SHAP), we explored how EER and the Proportion of Entrance/Exit Ridership (PEER) are subject to the built environment factors at the global level and the station level. The results indicated that more travelers are distributed in some regions of the island and some business parks, but these stations also demonstrate wide heterogeneity in terms of PEER. The density category variable shows a high positive correlation with EER, and shopping POI and intersection have a negative correlation with EER. Compared with EER, PEER is more relevant to more variables, especially the variables related to entrance/exit characteristics. According to the RF model, the influence of built environment variables on the EER and PEER also shows nonlinear and threshold effects. Our findings show that planners should consider the location and number of entrances/exits combined with built environment, in addition to the distribution of working and resident population. This study aims to improve passenger experience through enhanced travel convenience and comfort, providing a foundation for evidence-based policy development and urban design strategies in transit-oriented development.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"173 ","pages":"Article 103750"},"PeriodicalIF":6.3,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145049750","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}

Using the theoretical underpinnings of utilitarian and experience quality we surveyed 4200 public transport travelers in Sweden focusing on digital competence and environmental attitudes. Using structural equation modelling we find that both digital competence and environmental attitudes influence perceived quality and customer satisfaction so that travelers who 1) are able to deal with digital tools like smart-phone applications in public transport, and 2) have strong environmental attitudes, perceive the quality of the public transport service to be better.

At the same time, the third (vertical) dimension in urban and suburban areas – i.e. the lower airspace up to 500 m above the ground – has yet to be substantially exploited for transportation. Soon, technological advances in electric vertical take-off and landing (eVTOL) aircraft could enable the commercial use of Urban Air Mobility (UAM) for airport access. Through a case study in Bavaria, Germany, and Austria, this research aims to investigate the potential users’ willingness to pay for a novel UAM AirShuttle service, which could connect the airport of Munich with important points in its catchment area, and to analyse their transportation mode choices when accessing the airport. A stated preference mode choice survey was disseminated through an online panel during March 2023 in the catchment area of the airport to assess the current travel behaviour of the population, including the ownership of mobility instruments, the current state of airport accessibility and the satisfaction of the respondents (<em>N=</em>218) with the currently available modes. Furthermore, the survey investigated directly how much the respondents were willing to pay to use the AirShuttle and their sociodemographic background. The results were evaluated using descriptive statistical analyses and discrete choice modelling. The findings reveal that most respondents were satisfied with the current access modes and found their pricing reasonable. On the other hand, their willingness to pay for UAM services was lower than expected. This study yields important implications for the industrial stakeholders of UAM and for policymakers; by analysing the results, it was concluded that the expectations of the industry and potential customers regarding UAM pricing in the short term could be different and that its benefits and implications for society should be carefully weighed by policymakers.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"171 ","pages":"Pages 1025-1040"},"PeriodicalIF":6.3,"publicationDate":"2025-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144722934","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}

In response to growing public concerns over pedestrian safety, the Taiwan government implemented stricter monetary penalties for drivers failing to yield to pedestrians on June 30, 2023, representing a major legislative change aimed at deterring unsafe driving behavior, improving compliance with traffic laws, and fostering a more pedestrian-friendly road culture. This study evaluates whether this major legislative change has achieved its intended goals by examining its impact on the frequency and severity of road traffic incidents. Using a quasi-experimental study design, we found that the policy led to a gradual decline in incident frequency but an immediate reduction in crash severity. Its effect on incident frequency was particularly pronounced for pedestrian-involved crashes, with injury risks decreasing by approximately 11% for both car-to-pedestrian (RR = 0.89; 95% CI: 0.86, 0.92) and motorcycle-to-pedestrian crashes (RR = 0.89; 95% CI: 0.86, 0.91). In contrast, the likelihood of fatal outcomes dropped more sharply, with a 40% reduction observed across all crashes (RR = 0.60; 95 % CI: 0.42, 0.85). Our findings suggest that drivers may have quickly adapted their driving patterns to comply with the policy, reducing fatalities among crashes that did occur, while the slower decline in incident frequency likely reflects the time needed for broader behavioral changes, such as improved yielding, attentiveness, and rule adherence, to become routine. Notably, the policy's impact on reducing severity was stronger under low-visibility road conditions such as poorly lit settings, underscoring its particular effectiveness in mitigating risks in challenging driving scenarios. The findings underscore the importance of targeted legislative actions, such as stricter penalties, as an effective approach to promoting yielding behavior and enhancing pedestrian safety.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"171 ","pages":"Pages 1041-1049"},"PeriodicalIF":6.3,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144722935","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}

Although BLM holds promise for meeting diverse consumer demands, its viability hinges on unclear preferences between competing business models. This study investigates consumers’ heterogeneous preferences between CBM and BLM using stated choice experiments conducted in China, focusing on their non-compensatory behaviors. First, the latent class model identifies two distinct consumer groups: the CBM-preference subgroup (70.9 %) and the BLM-preference subgroup (29.1 %), with the latter exhibiting higher awareness of BLM and valuing its benefits. Subsequently, the latent class model with attribute cut-offs further reveals non-compensatory behavior. Overall sample attribute thresholds (i.e., cut-offs) reveal that 47.6 % of respondents require BLM purchase costs at least 20 % below CBM’s, while only 27.4 % accept 50 % higher operating costs than CBM. However, the attribute cut-offs differ significantly between the groups: the BLM-preference subgroup require a smaller average purchase cost discount than the CBM-preference subgroup (500 CNY vs. 800 CNY) and tolerate a larger annual operating cost increase (360 CNY vs. 120 CNY). When these cut-off values are exceeded, the probability of consumers choosing BLM decreases significantly, particularly among the CBM-preference subgroup. Additionally, the BLM-preference subgroup shows less concern about the cut-off for the distance to a battery swapping station. These findings enable operators to evaluate BLM’s viability from a consumer perspective and offer valuable insights into the sustainable development of innovative business models.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"171 ","pages":"Pages 1064-1075"},"PeriodicalIF":6.3,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144723906","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}
