1. 6. Pro-environmental travel behavior : The importance of attitudinal factors, habits, and transport policy measures

   Författare :Louise Eriksson; Jörgen Garvill; Annika Nordlund; Linda Steg; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; value-belief-norm theory; car habit; policy specific beliefs; car use reduction; acceptability; behavioral adaptations; travel demand management measures; transport policy measures; Psychology; Psykologi;

   Sammanfattning : The aim of this thesis was to study determinants of a readiness for pro-environmental travel behavior in households. Four empirical studies were conducted examining reduction in car use (Study I), acceptability of transport policy measures (Study II and III), and behavioral adaptations in response to travel demand management (TDM) measures (Study IV).

3. 7. Are We There Yet? Combining qualitative and quantitative methods to study the introduction of CAVs in Sweden, and potential travel demand effects

   Författare :Ella Rebalski; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; travel demand; Connected and Autonomous Vehicle; drivers; force field analysis; Value of Travel Time; sociotechnical transition; DPSIR; pressures;

   Sammanfattning : By law, Sweden must reach net-zero emissions of greenhouse gases (GHGs) by 2045. Domestic transportation is one sector in which GHG emissions can be reduced substantially. LÄS MER

4. 8. Issues in Urban Travel Demand Modelling : ICT Implications and Trip timing choice

   Författare :Maria Börjesson; Staffan Algers; Kay Axhausen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Journey; Mathematical model; Origin traffic ; Time; Telecommuting; Journey time; Variability; Stated preference; Delay; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; 11 Road: Personal transport; 11 Road: Personal transport;

   Sammanfattning : Travel demand forecasting is essential for many decisions, such as infrastructure investments and policy measures. Traditionally travel demand modelling has considered trip frequency, mode, destination and route choice. This thesis considers two other choice dimensions, hypothesised to have implications for travel demand forecasting. LÄS MER

5. 9. Communication technology and travel demand models

   Författare :Maria Börjesson; KTH; []
   Nyckelord :;

   Sammanfattning : Transportation planners have traditionally focused onphysical travel only, and disregarded the fact that other modesof communication may influence travel demand. However, moderntelecommunications are rapidly increasing the accessibility toactivities that previously only could be reached by physicaltransportation. LÄS MER

7. 10. Uncertain demand prediction for guaranteed automated vehicle fleet performance

   Författare :Sten Elling Tingstad Jacobsen; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mobility-on-Demand; Travel Demand Uncertainty; Energy Efficiency; Chance Constraint Optimization; Gaussian Process Regression; Stochastic Model Predictive Control; Fleet Opti- mization;

   Sammanfattning : Mobility-on-demand (MoD) services offer a convenient and efficient transportation option, using technology to replace traditional modes. However, the flexibility of MoD services also presents challenges in controlling the system. One of the major issues is supply-demand imbalance, caused by uneven stochastic travel demand. LÄS MER
