The effect of tailored information for the uptake of carsharing, evidence from a field experiment in Oslo
No full textAlice Ciccone, Paal Brevik Wangsness, The effect of tailored information for the uptake of carsharing, evidence from a field experiment in Oslo, Journal of Environmental Economics and Management, Volume 130, 2025, 103121, ISSN 0095-0696, https://doi.org/10.1016/j.jeem.2025.103121.Reducing reliance on private cars is essential for achieving a sustainable urban transport system, with carsharing offering a potentially valuable complement to public transport, walking, and biking. This study evaluates whether personalized information provision can promote carsharing adoption through a large-scale, pre-registered field experiment in Oslo, Norway. Car owners with older, low-utilized vehicles were randomly assigned to a control and treatment group based on their residence postcode. About 20,000 car owners in the treatment postcodes received emails and were exposed to an online calculator that compared the costs of owning a car versus using a carsharing service for their travel needs, while the control group received no intervention. The results show a 15% increase in carsharing uptake in treated compared to the control areas, equivalent to approximately 400 new sign-ups over six months. By leveraging objective data, this study provides causal evidence of the impact of tailored information on carsharing adoption.The effect of tailored information for the uptake of carsharing, evidence from a field experiment in OslopublishedVersio
Expanding the understanding of universal design beyond technical solutions and physical environment – 8 policy intervention areas

Moreover, the freedom of mobility—often taken for granted—is a crucial aspect of citizens' quality of life. Despite this, substantial portions of the population experience barriers that constrain their mobility. This paper demonstrates that adopting a holistic approach to universal design is more effective in reducing social exclusion for people with disabilities and making the public transport system accessible to as many people as possible. This is achieved by broadening the scope of user groups' needs and moving beyond universal design approaches that primarily focus on technical interventions and the physical environment. Based on a literature review of studies on universal design in transport systems, we identify a comprehensive set of barriers experienced by a wide range of user groups and the necessary interventions to mitigate these barriers. User groups include people with cognitive, intellectual, and psychosocial impairments, as well as those with respiratory conditions (asthma, allergies, COPD), gastrointestinal issues, pain, and seizure disorders, in addition to the classical impairments that research and policy have traditionally focused on (visual, hearing, mobility). Furthermore, we address the needs of user groups such as children, the elderly, and people with strollers. Our findings illustrate that policy measures must address organizational, individual, and social environments, in addition to the physical environment, to create a universally designed transport system for all.Expanding the understanding of universal design beyond technical solutions and physical environment – 8 policy intervention areaspublishedVersio
Does e-scooter ownership matter? A comparison of usage patterns and mode replacement effects of shared vs. personal e-scooters
No full textJørgen Aarhaug, Lars Even Egner, Nils Fearnley, Does e-scooter ownership matter? A comparison of usage patterns and mode replacement effects of shared vs. personal e-scooters, Research in Transportation Economics, Volume 113, 2025, 101626, ISSN 0739-8859, https://doi.org/10.1016/j.retrec.2025.101626.E-scooters have changed from being an urban novelty to becoming an established phenomenon. Parallel to this maturing process of the technology the literature on e-scooters has expanded rapidly, in particular related to the shared e-scooters. However, the literature on privately owned personal e-scooters is still relatively slim.
Privately owned and shared e-scooters are accompanied by different advantages and disadvantages. While parking and littering problems cause considerable unrest and opposition against shared e-scooter schemes, these problems are virtually non-existent with personal e-scooters. However, and in contrast to privately owned personal e-scooters, shared e-scooters obey maximum speed, size and engine power legislation and other regulations that can be enforced with geofencing, like speed, parking, and zone restrictions.
We find that personal e-scooters replace car trips to a much larger extent than the case with shared e-scooters, while shared e-scooters are more often used in conjunction with public transport. We also find differences in e-scooter ownership along the urban-rural axis. The relative share of personal e-scooters is increasing with distance from city centres.publishedVersio
Changes in road safety following regional administrative reforms in Norway
Full text linkRune Elvik, Tor-Olav Nævestad, Jenny Blom, Lars Even Egner, Vibeke Milch, Markus Bugge, Håkon Endresen Normann, Erland Skogli, Changes in road safety following regional administrative reforms in Norway, Accident Analysis & Prevention, Volume 214, 2025, 107969, ISSN 0001-4575, https://doi.org/10.1016/j.aap.2025.107969.A reform of regional government in Norway was implemented on January 1, 2020. The management of county roads was transferred from the National Public Roads Administration to the counties. The number of counties was reduced from 19 to 11. In 2022 it was decided to split some of the counties that were merged in 2020, and the number of counties increased to 15 from January 1, 2024. This paper studies whether these reforms were associated with changes in the number of injured road users on county roads. Four counties and the city of Oslo were included in the study. The city of Oslo was not affected by the reforms in 2020 and 2024. The other counties were affected either by: (1) Transfer of the management of county roads only (one county); (2) transfer of the management of county roads and merger with another county (one county); or (3) transfer of the management of county roads and merger with another county, followed by splitting up the merged counties (two counties). A before-and-after study with comparison group using county roads as treated group and other public roads as comparison group, and 2010–2019 as before-period and 2020–2023 as after-period found very small changes in the number of injured road users. Trends established during 2010–2019 continued almost unchanged after 2020. It is concluded that the regional administrative reforms were not associated with any detectable changes in road safety in the counties included in the study.Changes in road safety following regional administrative reforms in NorwaypublishedVersio
Does adolescent experience influence mobility later in life? A propensity score matching approach
No full textErik B. Lunke, Does adolescent experience influence mobility later in life? A propensity score matching approach, Journal of Transport Geography, Volume 123, 2025, 104129, ISSN 0966-6923, https://doi.org/10.1016/j.jtrangeo.2025.104129.While research shows that car restrictions and investments in sustainable transport infrastructure reduces car use, less is known about the influence of social norms and childhood experiences in shaping mobility behaviour. This study examines the impact of growing up in a car-owning household on car ownership later in life, utilizing Propensity Score Matching (PSM) and longitudinal registry data from Norway. The analysis reveals that experiences in the parental household at age 18 significantly influence car ownership in adulthood (at age 30), with a modest effect size of 4–5 %, after controlling for sociodemographic and neighbourhood factors. These findings suggest that traditional policy measures aimed at reducing car use may need to be complemented by public awareness campaigns to address deeply ingrained mobility behaviors shaped by early life experiences.Does adolescent experience influence mobility later in life?

ISSN 1361-9209, https://doi.org/10.1016/j.trd.2025.104665.To achieve local and national climate goals, it is essential to explore new policy instruments. This article examines the effects of introducing a non-intrusive policy instrument aimed at reducing car use. Specifically, we investigate the short-term behavioral impact of providing personal emission information to employees. Through a field experiment among municipal employees in Sarpsborg (Norway), we assess whether receiving personal emissions information related to municipal climate goals increases the intention to reduce car use and whether there are any short-term reductions in emissions from commuting. Our findings indicate that providing personal emission information has a small yet non-negligible effect on the intention to reduce the use of fossil-fuel cars. Equally important, we find a modest treatment effect on individual transport emissions. This study contributes to the literature on policy instruments by examining the behavioral effects of a relatively unexplored and innovative approach.Behavioral and intentional effects of providing personal emission information: An experimental approachacceptedVersio

Using panel data from repeated choice experiments with a large sample of Norwegian metro and train users during and after the pandemic, we investigate how the marginal valuation of travel time varies depending on crowding levels and passengers’ positions when sitting or standing. Based on mixed logit models and likelihood ratio tests, we find evidence that position does indeed matter: standing close to the door is preferred over other standing positions in the carriage. Regarding COVID-19, we find that crowding costs are lower after the pandemic but cannot reject the hypothesis that this reduction is independent of position. A key novelty of our study lies in the choice card layout, which contributes to the literature on crowding valuation by providing strong evidence that choice card presentations specifying passenger positions yield higher estimated crowding costs compared to variants where position is not specified.Travellers’ valuation of sitting and standing positions in crowded metros and trainsacceptedVersio
Extracting Commuters from Automated Road Traffic Counters: A Gaussian Mixture Approach
Full text linkBrustad, H.K., Midtbø, J.E., Tomba, G.S. et al. Extracting Commuters from Automated Road Traffic Counters: A Gaussian Mixture Approach. Data Sci. Transp. 7, 9 (2025). https://doi.org/10.1007/s42421-025-00123-7Assessing traffic patterns is important for many applications such as rush hour traffic management, cross-border commuting statistics, transportation disruption assessment, and crisis management. We present a method for detecting commuting patterns from time-detailed traffic sensor data. Our method uses Gaussian mixture models to identify morning peaks that also exhibit expected variation patterns over weekends and holidays as corresponding to commuting. We apply the method to detect the variation in commuting between countries in the Nordics during the disruptions caused by the COVID-19 pandemic. Results show that the commuting traffic experienced a smaller decrease (42–71%) than the total traffic (87–92%) during the pandemic. For Finland and Sweden, both types of traffic have in 2023 returned to approximately the same level as before the pandemic, while the traffic between Norway and Sweden has only recovered to about 73% of the pre-pandemic level. Our methods can be applied in real-time to provide useful information for applications.publishedVersio
Co-producing tools for integrating visitor management in municipal planning – lessons from a Norwegian case study
Full text linkLanda-Mata, I., Knapskog, M., Gundersen, V., & Rustad Pettersen, G. (2025). Co-producing tools for integrating visitor management in municipal planning – lessons from a Norwegian case study. Planning Practice & Research, 1–26. https://doi.org/10.1080/02697459.2025.2528118This paper explores how visitor management can be operationalized to support sustainable development of peripheral mountainous communities facing tourism pressures. It argues for anchoring visitor management into municipal planning to align tourism and second home development with local community needs and goals. Building on results co-produced through interdisciplinary and collaborative case-study research, the paper presents six methods to attend to the needs of locals and visitors, while shielding natural areas and wildlife. Moreover, it illustrates how planners can deploy these methods to incorporate relevant knowledge into planning, while reflecting on the research-practitioner collaboration for future research and planning practice.Co-producing tools for integrating visitor management in municipal planning – lessons from a Norwegian case studyacceptedVersio
What proportions of different transport modes do e-scooters replace? A meta-analysis
No full textNils Fearnley, Knut Veisten, What proportions of different transport modes do e-scooters replace? A meta-analysis, Journal of Cycling and Micromobility Research, Volume 5, 2025, 100082, ISSN 2950-1059, https://doi.org/10.1016/j.jcmr.2025.100082.This paper presents a meta-analysis of stand-up e-scooters’ mode replacement, based on outcomes from one hundred studies and dataset collections. The material includes scientific publications and grey literature from Europe, North America and Oceania. We aggregate the various replaced transport modes into three groups: private motorized vehicles, public transport and active transport. The mode replacement outcomes are survey-based, primarily directed towards e-scooter users. The mode replacement question is either about what mode would have been used on the last trip if the e-scooter were not available or about general changes in trip frequency of other modes after starting using e-scooter. Site-specific characteristics are added to the characteristics of the surveys. Meta-regressions show that the proportions of replaced private motorized vehicles and public transport are primarily associated with the proportions of these modes in the cities’ transport/commuting at the outset. Active transport represents the largest proportion of modes replaced by the e-scooter, but with less explained variation with respect to site-specific characteristics. We derive quality-corrected meta-analytic estimates of e-scooter mode replacement proportions from a subset of the meta-data.What proportions of different transport modes do e-scooters replace?
