Godstransporter : Utveckling, mätning och samband

Sammanfattning: Abstract  Sweden is an import and export dependent country and the main means of transportation of freight is by road transportation. Road transportation includes light to heavy trucks and are used for all types of purposes, for example from warehouse to market or from storage to building site.  The aim of this study is to describe how freight generation is calculated and predicted. Additionally, it aims towards analyzing the connection between economic growth and freight transport. Further the study seeks to describe the development of freight transport in Sweden. Lastly the study seeks to see how much freight a new investment in infrastructure in the shape of a grocery store would generate in Umeå. This is accomplished by utilizing a tool developed by Trafikverket, analysis of governmental documents and empirical evidence. Previous research has been used to understand the importance of road planning and the effect it has on urban environments and further deepening the knowledge of freight traffics impact on not only economy. Freight generation is calculated by using different types of models developed by Trafikverket. These tools are called EVA, Sampers, Samkalk, Samgods and the Traffic generation tool. The traffic generation tool is the only tool of the five which sole purpose is to forecast traffic generation. However, the tool poorly estimates the amount of freight generated by a new investment. The results show that economic growth and freight transport have a strong connection with each other. A new grocery store in Umeå would generate 42 new commercial traffic vehicles which includes freight.  The conclusion is that the availability of analyze freight generation of new investment in infrastructure without Trafikverket is almost impossible. This is an issue because of the various consequences that freight transport entails, such as lowered air quality, worsened traffic safety, congestion in urban areas. To be able to safely gauge the amount of freight a project will generate is therefore an important step in sustainable development.                        Key words: Freight generation, Freight transport, economic growth, urban and road planning
