The public and private sectors are making significant investments in electric vehicle charging infrastructure, however, the design, planning, and rollout of charging infrastructure tends to be siloed by mode (i.e., charging needs for passenger vehicles, transit buses, trucks, e-scooters, and other modes are not considered together). Given the ever-increasing interactions among these electrified transportation modes, there is growing interest in how to better integrate the design and delivery of charging infrastructure, such as through shared charging hubs.

To help policy makers and transportation agencies make more informed decisions regarding the planning and design of charging infrastructure, UC Riverside researchers developed a model for determining the optimal location, configuration (i.e., number of chargers, power capacities), and charging schedules for shared charging hubs serving cars and transit buses with the goal of reducing greenhouse gas (GHG) emissions. The model was then applied using Contra Costa County in California as a case study.
