HighlightsFormulates a VRP with path selection and heterogeneous vehicles.Provides an algorithm to determine load-depended emission-optimal paths.On average between 2 and 3 emission-optimal paths exist in real-world road networks.About 4% GHG emissions can be saved by path selection in simple problem instances.
AbstractIn this paper, we formulate an emission-minimizing vehicle routing problem with heterogeneous vehicles and give rise to the effects of path selection. We take into account different paths for traveling between two locations differing with respect to their emissions. Computational experiments with artificial and real-world data illustrate the effects of path selection by considering networks with different road types like urban roads and highways. The experiments suggest an emission saving potential of about 2–4%. We conclude that in reality a larger emission reduction potential exists when multiple paths are considered in transportation planning.
