A speed pedelec (SP), i.e. a fast electric bicycle with a maximum pedal-assisted speed of 45 km/h and a maximum continuous rated motor power of 4 kW, is a good alternative to cars as a commuting vehicle for certain distances. Qualitative studies identified the existing motivations for this uptake, but a model describing the specific factors driving this adoption, linked to empirical validation, is missing. This paper suggests a new SP adoption model based on several existing adoption theories and tests the theory through an experimental trial with a pre-test and post-test measurement. The study reveals that attitude formation is influenced by several factors, including Trust, Result Demonstrability, Design, Relative Advantage and Ease of Use before the test period. After the test period, however, the set of influencing factors narrows, with only Design and Ease of Use remaining significant predictors of attitude formation. This indicates that the test period not only reinforces certain perceptions but also filters out less impactful attributes, concentrating participants’ attitudes around the usability and design of the speed pedelec. The findings confirm that attitude formation towards speed pedelecs is instrumental in driving the intention to adopt them as commuting vehicles, with the test period playing a key role in reshaping perceptions. These insights are valuable for marketers and policymakers aiming to encourage active mobility, highlighting the importance of emphasising specific characteristics like design and usability to potential adopters.</div></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":"194 ","pages":"Article 104414"},"PeriodicalIF":6.3,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143419883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is wide global heterogeneity in the EV adoption rates among various countries. The manifestation of wealth inequality in the proliferation of EVs is an area of immense importance for policymakers interested in calibrating EV incentives by socio-economic characteristics. Since the predominant mode of personal transport is not the same in all countries, only a particular category of EVs can be studied to probe the impact of wealth inequality. India, due to its economy and population size, along with the sub-national level of wealth inequality, is suitable for a study on the relationship of EV adoption with wealth inequality. Two-wheelers dominate the Indian vehicular spectrum, and the sale of electric two-wheelers in India has picked up in the last five years. This study explores the impact of wealth inequality on electric two-wheeler sales in India. We use Instrumental Variable Quantile Regression (IVQR) and smooth IVQR method on the district-level data for India. Issues of endogeneity and heterogenous treatment effect are addressed through instrumental variable and quantile regression approaches, respectively. This study finds that wealth inequality is not only correlated with EV adoption, but also, the association is more pronounced in high EV adoption districts. These findings have serious policy repercussions because inequality-driven mobility transition can bring forth long-term undesirable outcomes for both economic growth and sustainability. Though the findings of this study are in the context of the Indian EV market, the inferences drawn are of global application due to increasing emphasis on EV adoption all over the world, which mostly overlooks the wealth distribution at the sub-national level.</div></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":"193 ","pages":"Article 104407"},"PeriodicalIF":6.3,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143403692","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}

As information of ride-hailing demand in most of the cities is not available, assessing the spatial transferability of ride-hailing demand models is an important research problem. To address this problem, this study aims to develop a ride-hailing demand prediction model using trip information available from ride-hailing service providers and to test the spatial transferability of the model. Using aggregated trip data, we have developed ride-hailing generation and attraction prediction models using several well-known machine learning algorithms such as random forest, extreme gradient boost, support vector machine, and artificial neural network for two study areas including the New York City and Chicago with similar built environment and land use characteristics. The random forest and extreme gradient boost models have superior performance for predicting ride-hailing demand with both the training and testing data in the intra-city level. The developed models for the New York City are later used to predict the ride-hailing demand of Chicago using two different transfer learning approaches. A knowledge transfer approach shows better transferability potential of ride-hailing demand models with reduced error rates. An analysis of prediction errors suggests that the models achieve better accuracy to predict demand on areas near central business districts or during peak periods.</div></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":"193 ","pages":"Article 104413"},"PeriodicalIF":6.3,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143395097","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}

The simultaneous planning of transport networks (e.g., optimizing transit services) and land use (e.g., planning activity locations), along with the implementation of environmental policies, collectively influence individuals’ activity and travel choices, thereby impacting carbon emissions. This paper presents a carbon credit charge scheme without initial credit allocations. Under this scheme, travelers are required to pay credits for emitting carbon dioxide and other greenhouse gases based on their chosen mode of transport, travel route, and departure time. We develop a bi-level programming model to capture the interaction between transit service headways, activity location plan, credit price, and their effects on individuals’ activity and travel choice behaviors. In the upper-level model, we optimize transit service headways and activity locations as well as credit price to attain green mobility and equity goals. In the lower-level model, we account for travelers’ heterogeneity in value of time and propose a comprehensive framework to schedule their activity and travel choice behaviors within a multi-modal transport network using a time-dependent activity-based approach. With our proposed model, we comprehensively analyze the activity-travel choice behaviors of heterogeneous travelers and resulting carbon emissions. The application of our proposed model is demonstrated using the Nyguen-Dupuis network.

Despite these benefits, consumers still prefer HD over OOHD for their last-mile e-commerce deliveries. While the convenience of HD is a core feature of online shopping, a question arises: Can OOHD offer better customer utility and reduce the delivery costs of last-mile logistics? Motivated by observed industrial practices, this study adopts a game-theoretic approach to analyze the strategies concerning a customer’s preference for delivery (HD vs. OOHD) and the switching (from HD to OOHD) behavior in response to an e-commerce firm’s self-pickup discount. A distinctive feature of this work is the conceptualization of an e-commerce firm’s orientation towards the triple bottom line goal of meeting consumer expectations (people), financial gains (profit), and reducing environmental impact (planet), collectively termed as the <em>syncretic value</em> in this paper. Setting the syncretic value as the business objective function, we obtain the equilibrium solutions on the discount (for OOHD) and shipping charge (for HD) that would entice a switch to OOHD. Unlike the current practice of some e-commerce delivery markets offering a flat rebate for self-pickup, our results reveal that the e-commerce firm should peg the self-pickup discount based on the online product’s price and levy a shipping charge for low-price products to encourage self-pickup. Online retailers should focus on low-price products for the OOHD-based incentivization scheme for better profitability. We provide a comparative analysis between the HD-only and hybrid (HD with OOHD) delivery models to guide the e-commerce platform operators in positioning their business models and customer engagements. The results suggest that including the syncretic value in the business objectives not only increases consumer utility (more delivery choices) and profitability of the e-commerce firm (lower delivery costs) but also addresses the environmental impact of urban logistics, thus contributing to the sustainable development goals.</div></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":"193 ","pages":"Article 104309"},"PeriodicalIF":6.3,"publicationDate":"2025-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143372408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are two types of these systems: station-based and free-floating. The former is characterised by the presence of stations in which a user can pick up or drop off a vehicle. The latter offers users the same functions but, where enabled, anywhere within the service area. Free-floating systems may appear more equitable and convenient than station-based ones, as stated in literature, but on the other hand, they can lead to unauthorised and irregular parking, obstructing pedestrians and vehicle flow. To reduce disordered parking, one of the possible solutions is to implement stations also in free-floating systems. However, this can reduce their attractiveness, forcing users to walk longer and making the system less fair. To address these issues, we proposed to convert a free-floating system into a mixed one with free-floating and station-based geofenced service sub-areas. The station locations are defined through a new multi-objective problem with the aim of finding a compromise among three objectives: the maximisation of drop-off station demand to minimise irregular parking, the minimisation of users’ walking distances in active and passive accessibility, and the minimisation of inequality in walking distance changes due to the conversion to a mixed system. This model was applied to a real case study and shows that our proposal can be of help for municipalities and operators in choosing fair station locations or a trade-off solution based on the importance they attach for one objective compared to the others.</div></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":"193 ","pages":"Article 104390"},"PeriodicalIF":6.3,"publicationDate":"2025-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143349778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work investigates different pricing policies for public parking, including dynamic pricing and Machine Learning-based strategies that can directly optimize policy goals, such as improving mobility or accessibility. In doing so, we pay special attention to an aspect often ignored when implementing pricing policies for public parking: fairness with regard to equal outcomes for different social groups. Since the effects of pricing policies are very sensitive to financial inequality, we specifically investigate the impact of policies on different income groups. As a foundation for these experiments, we introduce a parking simulation featuring an empirically calibrated behavioral model of parking. We find that (1) dynamic pricing schemes may negatively impact fairness; (2) fair pricing for parking may require different fees for individual social groups; (3) focusing on single policy goals when devising pricing for parking results in unintended consequences; (4) Machine Learning shows potential for creating pricing strategies combining different policy goals.</div></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":"193 ","pages":"Article 104389"},"PeriodicalIF":6.3,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143259791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing studies have primarily applied aggregate public transport or car job accessibility measures to examine the impact on employment probabilities of (sampled) disadvantaged groups in mainly metropolitan areas. We improve on these existing studies by combining national administrative employment micro datasets of the full working-age population of the Netherlands, segmented by educational level, with a novel composite public transport-and-bicycle accessibility measure to matching job opportunities and national vehicle registration data for the first time. This allows us to examine differential employment effects of job accessibility by public transport in combination with the bicycle for different educational groups at the national level. In our employment models, we control for endogeneity of both job accessibility and vehicle ownership in relation to employment status through an instrumental variable approach. The study finds that jobs for higher educated tend to be concentrated in and around the city centres, while jobs for the lower educated are more often located outside these prime accessibility areas, thereby reducing job accessibility among low-educated groups. The study further identifies that employment, in particular of low-educated individuals, is sensitive to higher levels of public transport-and-bicycle job accessibility, but in contrast with prior studies we also find that middle- and higher educated groups could benefit from improved job accessibility. The usage of detailed job accessibility measures and employment micro datasets of the full population thus seem essential to accurately assess the relationship between job accessibility and individual employment probabilities.

Recent scientific literature has highlighted the importance of inclusive strategies, demonstrating a strong correlation between the gender gap in cycling participation and the overall cycling levels within a given area. This indirect relationship necessitates identifying the factors that promote gender-inclusive bicycle usage. Focusing on the French context, the key objectives of this empirical research are (i) measuring gender inequalities in the use of bike and emerging micromobility at the municipal level, (ii) assessing the influence of built environment and urban design on the gendered modal share of cyclists, and (iii) comparing and clustering the investigated French cities with the development of an index that takes into account gender equity, the modal share of cycling, and the perceived bikeability. By drawing from two distinct databases based on the use of micromobility and the subjective bikeability of cities and by conducting quantitative observations, this original study sheds light on the significant connection between gender-balanced cycling distribution, cycling modal share, cycling infrastructure presence and perceived bikeability. This paper concludes that encouraging women to embrace cycling is not solely dependent on achieving a critical mass of cyclists or building cycling lanes. Instead, it emphasizes the need for the development of a comprehensive ’bicycle system’ that takes into account all aspects of bikeability. This innovative outcome leads to the categorization of examined cities based on the development of a gender-inclusive with cycling quality index. This exploration underscores the vital role of urban planning and offers recommendations for stakeholders regarding future policy initiatives.</div></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":"193 ","pages":"Article 104379"},"PeriodicalIF":6.3,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143259789","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}
