Abstract:
A combination of electric-automated technologies has been hailed as a greener alternative to a traditional internal combustion engine and a solution to the increasing energy demand by the transport sector. Whilst many automated electric vehicles (AEVs) have been deployed in pilot projects over the last decade, their energy consumption has not been empirically tested, especially in rural areas where terrains are more challenging than typical urban road geometries. Since the specified energy consumption by manufacturers can often underestimate vehicles’ actual energy consumption, field data is necessary to analyse how much energy is spent in real-world scenarios. Utilising data collected from the Digibus project, an automated electric shuttle service deployed in the municipality Koppl, this master thesis aims to examine the energy consumption of an automated bus service in a peripheral terrain with up to 8 % slope. A digital elevation model was calculated and a panel regression analysis was employed to explore the impact of rural road characteristics on the vehicle’s energy consumption. The results confirm a correlation between energy consumption and road gradient and indicate that steep uphill slopes cause a significantly higher energy consumption than flat terrains. However, they also illustrate how significantly less energy is spent on downhill slopes compared to flat terrains. These findings imply that the counteracting effects will likely balance each other out leading to a similar average energy consumption compared to urban areas. The energy consumption of the AEV was also evaluated against traditional internal combustion engines of comparable size and was found to perform more energy-efficiently in all tested scenarios. Although there is still a lot of research and advancement of technology necessary for a big roll-out of AEVs, this thesis shows how much potential they have to reduce energy consumption within transport in both urban and rural scenarios.
