11. Active school transportation : Understanding the parental decision-making process
Sammanfattning : Few children and adolescents reach the recommended levels of daily physical activity. This trend is evident in the countries examined in this thesis: Sweden and Spain. LÄS MER
12. Intermodal Road-Rail Transportation for Express Transport Services
Sammanfattning : Express transport services are produced in highly modularised transport systems, a fact that implies that one subsystem can be exchanged for another without causing a need for major changes in other parts of the system. Express goods are not common on a large scale in freight railway transport systems, as those are often not considered reliable enough for time-critical goods. LÄS MER
13. Valuation of goods transportation characteristics : A study of a sparsely populated area
Sammanfattning : This study describes how consumers and providers of transportation services in a sparsely populated area valuate different transportation characteristics and estimates how these valuations might affect the total goods flows and the flows on individual Origin-Destination links. It also tests Stated-Preference methods as a tool for valuating transportation characteristics. LÄS MER
14. Computer-based decision support for handling uncertainty in railway traffic and transportation
Sammanfattning : Railway transportation has great potential, but interdependencies in the railway traffic make trains very sensitive to disturbances, which can bedifficult to handle. Using railway in an intermodal transport chain may complicate the interconnections with other modes if there is large uncertainty in the performance of the railway. LÄS MER
15. Complexity in Transportation and Logistics Systems An Integrated Approach to Modelling and Analysis
Sammanfattning : The basis for the thesis is to assess the usefulness of describing and analysing transportation and logistics systems as being complex systems. The reason and assumption being that in the future more integrated and sophisticated systems and solutions will be demanded. LÄS MER
