Several electric road system technologies that enable in-motion charging of electric vehicles are nearing market readiness. However, substantial contribution to decarbonization requires rapid deployment on an international scale. Investment is discouraged by prior research that has identified that declining battery costs may eventually leave the infrastructure a stranded asset. We explore under what circumstances electric roads offer effective and low-risk decarbonization of European heavy-duty road freight. Transport system dynamics are explored and quantified, through pairwise comparison of scenarios with and without electric road incorporation, using a purpose-built agent-based simulation (MOSTACHI). Prior stranded asset risks are confirmed, but we show that policy that encourages high electric road utilization can correct for market failures and make the infrastructure a no-regret investment in much of Europe – never yielding worse outcomes than not investing. Electric roads are shown to be an effective risk mitigation strategy, achieving market-driven phase-out of fossil fuels before 2050, also in pessimistic scenarios where static charging alone would be insufficient. Electric roads reduce levelized system cost by 0–17%, greenhouse gas emissions by 7–63% (2030 to 2050, cumulative) and battery mineral demand by 20–40%. Benefits are maximized with early and predictable deployment. 

This study developed a multi-day electric truck trip cost model to analyse cost-minimising carrier use of stationary charging, battery swapping and catenary electric roads in the EU TEN-T road network setting. Each of these three charging options has its own advantages for carriers, thus motivating the analysis. The multi-day truck segment accounts for almost one-fifth of all truck tonne kilometres within the EU, making it important to consider in the quest to decarbonise this sector. Nevertheless, this segment has until now been sparsely analysed in the literature on truck electrification. Based on the scenario analysis, the carrier truck trip costs in the current state (year 2024) and future state (year 2035) was analysed. The current state analysis revealed that catenary electric roads are a cost-minimising option to carriers, whereas future state analysis revealed that catenary electric roads and swapping can perform on par while being cost-advantageous vis-à-vis stationary charging. The sensitivity of these findings to battery parameters, electric road user charges, swapping fee levels and charging alliances was reported. The implications of the findings for carriers, vehicle producers and policymakers were discussed.

This paper presents the results of a ranking-type Delphi study on the critical risk factors for the adoption of an electric road system (e-road) for trucks on the main motorways in Sweden. The investment cost of such a system is high, necessitating an upfront evaluation of the adoption risk factors to reduce the likelihood of budget overruns and project delays. Participating Swedish e-road experts (N = 52) from the public sector, private sector, and academia identified 32 unique risk factors, which were divided into five categories. The three most critical risk factors, as ranked by the experts, were ‘low expansion rate,’ ‘low utilization rate,’ and ‘lengthy public-sector evaluation.’ Overall, market and financial risks were ranked as more important than institutional, technological, and sustainability risks. This study has important implications for policymakers in countries considering e-road adoption.

The paper evaluates the social benefit of extending an electric road for trucks to secondary motorways. It provides an updated analysis of its social benefits on main motorways. Two options are evaluated: propulsion only and propulsion with recharging. The propulsion and recharging option is found to have higher social benefits, but trucks with larger batteries are a better option for secondary motorways. Plug‐in battery‐electric trucks with large batteries are found to yield higher welfare than electric roads on main motorways. The analysis includes sensitivity to fuel cost savings, truck usage, user charges, investment cost, and battery cost to identify inflection points where investing in electric roads becomes welfare-increasing.

The many challenges faced by instructors in distance education have been extensively documented in current literature. Nevertheless, the relative importance of such challenges has not been researched to the same extent. As instructors and institutions face limitations in terms of time and budget, the ability to effectively prioritise challenges becomes increasingly vital. This paper aims to investigate the relative importance of various distance education challenges to instructors. For this purpose, a ranking-type Delphi study of 90 instructors was conducted at a Swedish higher education institution of technology. In total 26 unique challenges were identified, out of which the top 13 challenges were further ranked by instructors. The ranking revealed that pedagogical challenges were regarded as being of highest relative importance, whereas technological and organisational challenges were of lesser significance. Instructors rated the following challenges as the most significant: lack of student responsiveness, diminished collaboration due to social distancing among students, substantial upfront course design investments by instructors, and limitations in instructor accessibility. These rankings were found to be largely consistent across different instructor characteristics. The findings of the study indicate the importance of investing in faculty training and support functions within higher education institutions to ensure the quality of distance education.

This study investigates the effect of three key firm characteristics (diversification, size, and age) on road freight companies’ early adoption of alternative fuel vehicles (AFVs). While previous studies have identified the determinants of the adoption intention of AFVs, a gap in the literature is research into firm characteristics and the early adopters of AFVs. Because early adopters play an important role in the diffusion of innovation, it is imperative to fill this gap. Based on a survey of 156 Swedish road freight companies and logistic regression analyses, we report that firm size and diversification affect the early adoption of AFVs. In addition, the partial impact of the importance of driver comfort and payload capacity on early adoption of AFVs has been reported. Other factors, including purchase price, fuel cost, and truck refueling efficiency, were not found to discriminate early adopters of AFVs from those who had not yet adopted AFVs. These findings imply to policymakers that the current instruments in use in Sweden, including the greenhouse gas mandate and the relatively high taxation on diesel fuel, have led to the adoption of AFVs by larger road freight companies. For vehicle producers aiming to scale up the production and sales of AFV, the findings suggest the benefit of targeting diversified and larger road freight companies in the first place. © 2024 The Author(s)

This study analyzes the determinants of road freight companies' adoption intention regarding the electric road systems (e-roads) on Swedish motorways. A research model was developed based on the technology adoption literature and Technology-Organization-Environment (TOE) framework. Survey data were gathered from 160 Swedish road freight companies, and structural equation modeling was performed to test the model empirically. The results reveal relative advantage, a technology characteristic, as the main determinant of road freight companies' intention to adopt electric road systems. The study contributes to the TOE framework by reporting on the indirect effects of technological and organizational determinants on organizational intention to adopt technologies. © 2023 World Scientific Publishing Company.

Mobile app ratings and reviews are important due to their influence on consumer behavior and the financial consequences for app developers and app platform providers. This paper contributes to prior work by analyzing how rating and review information in combination impact mobile app downloads. To achieve these ends, we utilize daily panel data of 341 gaming (hedonic consumption value-oriented) and productivity (utilitarian consumption value-oriented) apps tracked for almost two years from their release in the Apple App Store. Hence, we contribute to how ratings and reviews matter for the larger majority of apps, whereas previous research has mainly focused on either ratings' or reviews' impact on app performance for top-ranked apps. Results of fixed-effects regression analysis reveal different combinatory impacts of text review information (polarity, subjectivity, and review length) and rating information (average rating score, volume of ratings, and dispersion of ratings) on gaming versus productivity app downloads. Important implications of the findings for app developers and platform providers, and for future research into online ratings and reviews, are discussed.

This paper explores key drivers and their underlying rationales for infrastructure Public-Private Partnership (PPP) adoption in Sweden. A related aim is to compare the identified key drivers for Sweden in relation to what is known for other countries. Data was collected via semi-structured interviews with 16 Swedish private sector and public sector stakeholder PPP experts. The results reveal risk transfer to the private sector, reduction of total project costs, and increase in investment alternatives as particularly important key drivers in the case of Sweden. In a country comparison of key drivers Sweden was not found to mirror any specific country or group of countries, calling for deeper analysis. Moreover a few underlying rationales put forth for key drivers were in addition to those reported in the literature. This study contributes to the literature by identifying conducive factors for PPP adoption given sparse and infrequent past country use. Hence, the findings should be considered for Sweden and countries similar to it.

When launching a new app in one of the major app stores, the developer must decide how to generate revenues from that app. The decision includes whether to charge an upfront payment from the customer or make it free to download and whether to include in-app payments. In this study, we analysed the effect of these decisions on the amount of revenue an app generates and if it differs for gaming (hedonic value-orientation) and productivity (utilitarian value-orientation) apps. To analyse this effect, we used approximately two years of mobile app panel data from 330 newly launched US Apple App Store gaming and productivity apps. Based on random effects regression analysis, we report that free downloads combined with in-app payments are superior in revenue generation for gaming apps. By contrast, for productivity apps, relying only on either upfront payment for the app or on in-app payments generates the highest revenues. For gaming app developers, offering free to download apps is thus recommended. For productivity app developers, charging for either downloading or in-app features is more successful. This study complements existing literature by investigating revenue generation of new apps and the performance effect of specific revenue model options that developers must make in app store settings.
