1. 21. Estimering av efterfrågan på långväga persontransporter : En ekonomisk-teoretisk belysning av gängse modeller samt en ny ansats till uppskattning av efterfrågesamband

   Författare :Thomas Sonesson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Intercity travel demand; gravity model; legit model; entropy maximising; BoxCox; demand elasticities;

   Sammanfattning : This dissertation deals with the estimation of intercity travel demand. The purpose is to discuss the derivations and characteristics of existing models, to derive a demand model based on microeconomic theory and to estimate the parameters of the model in order to gain information on important characteristics of the transport system.

3. 22. Shared e-scooter usage patterns : Analysis of app and trip data

   Författare :Boel Berg Wincent; Erik Jenelius; Wilco Burghout; Johan Olstam; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; e-scooter; micromobility; elsparkcyklar; mikromobilitet; Transportsystem; Transport Systems; Transportvetenskap; Transport Science;

   Sammanfattning : There is an urgent need to shift the urban mode distribution towards public transportation, micromobility, and shared mobility as a critical step towards achieving sustainable cities. Micromobility, with shared e-scooters as the main driving force, has sprung up as a promising mode for cities since the late 2010s. LÄS MER

4. 23. Psychology for sustainable shared mobility: An investigation of the use of private cars and carsharing services

   Författare :Erika Martins Silva Ramos; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; carsharing; travel behaviour; sustainable transportation; trip purpose;

   Sammanfattning : What are people’s travel patterns – both users and non-users of carsharing and private cars in European cities? What are the main psychological aspects of and motives for making a travel mode choice? This thesis aims to investigate the relationship of habits with attitudinal, normative and motivational aspects to understand the use of private cars and carsharing. Study I presents a classification of motives considered relevant when selecting a mode of transport. LÄS MER

5. 24. Across landscapes and seascapes : The movement ecology of diving and flying guillemots and gulls during breeding

   Författare :Thomas J. Evans; Evolutionär ekologi; []
   Nyckelord :Uria aalge; Larus fuscus; Laridae; animal flight; foraging ecology; movement ecology; seabirds;

   Sammanfattning : Most seabirds breed colonially, at which time they make central-place foraging trips. Parents must collect food both for themselves and for egg production/chick-rearing. LÄS MER

7. 25. Travel mode choice and sustainability: A psychological investigation of the use of a private car and car sharing services

   Författare :Érika Martins Silva Ramos; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : This thesis discusses the implications of research-based decision-making to develop socially robust technologies, policies, and urban planning in the transport sector, aiming for an inclusive and more sustainable transport system. What are the travel patterns of both users and non-users of car sharing and private cars in European cities? What are the main psychological aspects of and motives for making a travel mode choice? Study I presents a classification of motives considered as relevant when selecting a mode of transport, and it examines the relative importance of driving habits, car attitudes, descriptive norms, and motives for transport mode choices for commuting, shopping trips, child-related trips, and leisure trips.
