      Flugel, Stefan Markus; Veisten, Knut; Rizzi, Luis I.; Ortuzar, Juan De Dios; Elvik, Rune (Journal article; Peer reviewed, 2018-09-22)
      Introduction The economic value of safety represents an important guide to transport policy, and more studies on individuals’ valuation of road safety are called for. This paper presents a stated preference study of the ...
    • Asymmetric preferences for road safety: Evidence from a stated choice experiment among car drivers 

      Flugel, Stefan Markus; Elvik, Rune; Veisten, Knut; Rizzi, Luis I.; Meyer, Sunniva Frislid; Ramjerdi, Farideh; Ortuzar, Juan De Dios (Journal article; Peer reviewed, 2015-04-29)
      Recent research has proposed fitting responses from discrete choice experiments to asymmetric value functions consistent with prospect theory, taking into account respondents’ reference points in their valuation of choice ...
    • Aversion to in-vehicle crowding before, during and after the COVID-19 pandemic 

      Flugel, Stefan Markus; Hulleberg, Nina (Journal article; Peer reviewed, 2022-08-16)
      Based on four consecutive stated choice surveys, we estimate changes in public transport user’s valuation (marginal costs) of in-vehicle crowding due to the COVID-19 pandemic in two Norwegian cities. Compared to the pre-COVID ...
    • Car drivers' valuation of landslide risk reductions 

      Flugel, Stefan Markus; Rizzi, Luis I.; Veisten, Knut; Elvik, Rune; Ortuzar, Juan De Dios (Journal article; Peer reviewed, 2015-02-28)
      Approximately one car occupant per year is killed as a result of landslides or avalanches in Norway, compared to 150–200 fatalities due to accidents. Still, protection from landslides is a major transport safety issue, ...
    • Competition and substitution between public transport modes 

      Fearnley, Nils; Currie, Graham; Flugel, Stefan Markus; Gregersen, Fredrik Alexander; Killi, Marit; Toner, Jeremy P; Wardman, Mark (Journal article; Peer reviewed, 2018-05-26)
      The management and understanding of modal split between public transport (PT) modes is of interest for numerous reasons. It may, for example, be desirable to stimulate passengers to switch from crowded buses and over to ...
    • The effect of health benefits on the value of travel time savings in active transport 

      Flugel, Stefan Markus; Veisten, Knut; Sundfør, Hanne Beate; Jordbakke, Guri Natalie; Hulleberg, Nina; Halse, Askill Harkjerr (Peer reviewed; Journal article, 2021-04-28)
      Introduction The valuation of travel time savings and the valuation of health effects are crucial in the economic appraisal of infrastructure projects that affect cycling and walking for transport. Current practices treat ...
    • Empirical speed models for cycling in the Oslo road network 

      Flugel, Stefan Markus; Hulleberg, Nina; Fyhri, Aslak; Weber, Christian; Ævarsson, Grétar (Journal article; Peer reviewed, 2017-11-23)
      Knowing the speed at which a cyclist travels is important in route and mode choice modelling. Empirical evidence suggests that it varies significantly in accordance with—among other things—infrastructure and topology. ...
    • Investigating observed and unobserved variation in the probability of ‘not travel’ as a behavioural response to restrictive policies 

      Flugel, Stefan Markus; Fearnley, Nils; Killi, Marit (Peer reviewed; Journal article, 2019-11-01)
      Besides technological improvements, restrictive car policies are likely to be the most effective measures for reducing greenhouse gas emissions from local passenger transport. Restrictive policies may lead some individuals ...
    • Methodological challenges in modelling the choice of mode for a new travel alternative using binary stated choice data - The case of high speed rail in Norway 

      Flugel, Stefan Markus; Halse, Askill Harkjerr; Ortuzar, Juan De Dios; Rizzi, Luis I. (Journal article; Peer reviewed, 2015-07-04)
      Binary stated choices between traveller’s current travel mode and a not-yet-existing mode might be used to build a forecasting model with all (current and future) travel alternatives. One challenge with this approach is ...
    • A minute of your time: The impact of survey recruitment method and interview location on the value of travel time 

      Halse, Askill Harkjerr; Flugel, Stefan Markus; Kouwenhoven, Marco; de Jong, Gerard; Sundfør, Hanne Beate; Hulleberg, Nina; Jordbakke, Guri Natalie; Lindhjem, Henrik (Journal article; Peer reviewed, 2022-05-26)
      Web-based stated preference (SP) surveys are widely used to estimate values of travel time (VTT) for cost–benefit analysis, often with internet panels as the source of recruitment. The recruitment method could potentially ...
    • Review and meta-analysis of inter-modal cross-elasticity evidence 

      Wardman, Mark; Toner, Jeremy P; Fearnley, Nils; Flugel, Stefan Markus; Killi, Marit (Journal article; Peer reviewed, 2018-10-21)
    • Triggers of Urban Passenger Mode Shift – State of the Art and Model Evidence 

      Fearnley, Nils; Flugel, Stefan Markus; Killi, Marit; Gregersen, Fredrik Alexander; Wardman, Mark; Caspersen, Elise; Toner, Jeremy P (Journal article; Peer reviewed, 2017-08-14)
      Mode shift is at the core of sustainable transport in all world cities; yet we know comparatively little about it. While there is ample evidence of within-mode demand effects, we know in general very little about what mode ...
    • Value of travel time by road type 

      Flugel, Stefan Markus; Halse, Askill Harkjerr; Hartveit, Knut Johannes Liland; Ukkonen, Aino (Journal article; Peer reviewed, 2022-08-03)
      Travel time is less costly if it is comfortable or can be used productively. One could hence argue that the value of travel time (VTT) of car travellers in economic appraisal should be differentiated by road type, reflecting ...
    • What Factors Affect Cross-Modal Substitution - Evidences from the Oslo Area 

      Flugel, Stefan Markus; Fearnley, Nils; Toner, Jeremy P (Journal article; Peer reviewed, 2017-11-27)
      The vast majority of studies on urban travel demand focus on the effect on the demand of one travel mode given a change in the characteristics of that same transport mode, for example, own-elasticities. comparatively little ...
