Abstract:The primary objective of this project was to understand Indiana resident’s perspectives on electric vehicles (EVs), including adoption incentives and barriers, awareness of adoption incentives, charging preferences, and general travel patterns. A secondary objective was to establish a framework for identifying EV users, detailing their trips, and generating predictions for EV adoption and usage. To achieve these objectives, a stated preference survey was conducted with 1,217 Indiana residents. Two datasets containing travel behavior data were incorporated to generate synthetic data. The survey results revealed that Indiana EV users are typically middle-aged males living and working in urban areas. EV users tend to drive more frequently than non-EV users and prefer owning EVs over leasing them. They consider home charging as a vital component of EV usage. Non-EV users identified purchase price and charging issues as the main barriers to adoption and are generally unaware of charging incentives. They are also less inclined to use public charging facilities due to their perceived unreliability. EV trips are usually short distance. The generated synthetic dataset aligned with real-world data, predicting future EV demand for the next 8 years. Under an optimistic scenario, the number of EVs could increase by 18 times above the 2023 levels. Under a pessimistic scenario, it could double. This project supports INDOT, and other stakeholders prepare for the increased EV usage resulting from the deployment of charging stations. To foster EV adoption, it is recommended to better promote EV incentives, develop workforce programs focused on used EVs, and provide segmented education about public charging infrastructure.
