Roundabouts and the Energy Consumption of Electrical Vehicles

Understanding how the energy consumption of electrical vehicles behave on intersections can be paramount to save on electricity and reduce the emissions of greenhouse gases. This study uses a large dataset of high-frequency trajectory data to verify the feasibility of intersection analysis and study how roundabouts fare against each other when it comes to the energy consumption of EVs. The results show that there can be a difference of 25-33% in the consumption inside roundabouts depending on their category. They also show that the speed of the vehicles as they enter the roundabouts correlates to their energy consumption in a polynomial fashion.
