Abstract
Transportation systems are undergoing a fundamental transition toward electrification. The shift to electrification, characterized by the widespread adoption of electric vehicles (EVs), the expansion of charging infrastructure, and the integration of renewable energy sources, has the potential to yield significant societal benefits. These include climate change mitigation, alleviation of air pollution, and enhancements in overall human well-being. However, the existing infrastructure related to transportation electrification, particularly in the domain of public chargers, remains inadequate to support this sweeping transition. This insufficiency has led to inconvenient EV charging experiences, impeded the establishment of a comprehensive nationwide charger network, and resulted in disparities in charging accessibility across diverse communities. To meet the increasing charging requirements of EVs and facilitate a seamless transition to electrified transportation, this study introduces a comprehensive analytical tool known as eTranSym. eTranSym is intended to address the following critical questions through its implementation in Los Angeles County: 1. How does the electrification process create public charging needs at the system and census tract levels?2. How do variations in travel demand and network functional supply impact the projection of public charging needs?3. How does the spatial-temporal distribution gap of charging infrastructure affect accessibility, especially in low-income and disadvantaged communities (DACs)?
