Analysing Heavy Vehicles Trip Chains - Potential for Energy Savings
The paper addresses empty trips in heavy vehicles. It will report a research approach to investigate trip chain patterns to identify potential wasteful empty trips and identify the types of vehicles and types of goods that are more likely to have empty trips. The analysis will be used to focus on possible ways of reducing these empty trip. The analysis will be based on the national trip diaries that are filled out for approximately 1200 vehicles every year and covering all trips undertaken during one week of operation. The individual diaries will be used to describe the different trip chains undertaken by the vehicles. The analysis will identify whether the trip chain patterns are the same within vehicle type and/or type of commodity. In relation to this analysis a specific focus will be on the empty trips. The paper will discuss whether there are certain patterns of empty trips that can be identified and possibly reduced. This detailed trip chain approach presented in this paper is unparalleled in other studies. The analysis is just beginning. This paper will report initial findings and outline what areas that will be of interest to investigate further. One area where the findings can be used is in freight transport demand modeling, in particular, for strategic modeling. The model approach will be in line with the approach by Holguin-Veras et al. (2003), but the investigation will contain more information as the specific trip chains are used for the analysis and modeling. The paper will address and outline how this modeling can be undertaken, however, the actual model will not be developed and/or estimated.
