Title:

Impact of Intersection Control on Electric Vehicle Energy Consumption

Accession Number:

Record Type:

Abstract:

This study quantifies the energy consumption of electric vehicles (EVs) for different intersection control types, including a roundabout, a traffic signal, and a two-way stop sign. A microscopic traffic simulation model was used to model drivers/vehicles and EV energy and fuel consumption models were used to estimate second-by-second energy/fuel consumption levels of the vehicles. The results indicate that the energy consumption patterns of EVs are significantly different from those of internal combustion engine vehicles (ICEVs). For example, for EVs approaching an intersection at 88 km/h, the roundabout was found to be the most energy-efficient intersection control, while the two-way stop sign was the least efficient. In contrast, for ICEVs, the two-way stop sign was the most fuel-efficient control, while the roundabout was the least efficient. The effects of traffic signal coordination on the energy/fuel consumptions of both EVs and ICEVs were also investigated. The results indicate that traffic signal coordination improves the energy efficiencies of both types of vehicles. However, the effect is less significant for EVs since more regenerative energy is produced when partial or poorly coordinated signal plans were implemented. The findings of this study suggest that EV regenerative energy is a major factor in energy efficiency, and EVs recover different amounts of energy in different urban driving environments. The results also support the strategic design of transportation facilities and the implementation of control strategies to increase the energy efficiencies of both EVs and ICEVs.
