Abstract:Electric vehicles, autonomous or manual, provide a valuable opportunity to address issues of environmental pollution, climate change, and national security. In recognition of the synergies between vehicle electrification and autonomy, this study addresses the facilitation of vehicle electrification in the prospective future era where autonomous vehicles become mainstream. Part 1 of this study proposes a methodology for scheduling deployment of electric charging facilities (charging guideways and charging stations) at AV dedicated lanes over candidate links of a road network over a long-term horizon period. The methodology is intended to assist highway agencies in decision support regarding the scheduling, locations, and operating capacities of the EV charging facilities, where the road users (travelers) minimize their travel times by selecting routes and their preferred vehicle type (AV vs. HDV). The bi-level model is solved using a Genetic Algorithm, and the results provide insights into the impacts of alternative scenarios of charging infrastructure investment. Part 2 of the study presents a methodology for environmentally sustainable electric charging station deployment, such that travelers experience a smooth shift from ICEVs to EVs over a lengthy planning horizon.
