Maxwell School Professor Saba Siddiki is part of a multi-institution research team that has been awarded $1.5 million from the National Science Foundation (NSF) to research public bus fleet electrification.

The funding is provided by the NSF’s Smart and Connected Community program and aims to foster a Community-Responsive Electrified and Adaptive Transit Ecosystem to tackle challenges that arise in the planning, operations and management of public bus fleet electrification.

According to Siddiki and fellow project researchers, public bus fleets—including transit and school buses—represent a prime opportunity for transportation electrification and associated improvements in environmental quality and health benefits in impacted communities.

The widespread adoption of electric buses has been hindered by an array of complex and interrelated planning, operational and managerial challenges, they say. Among them are range limits, long charging time, expenses, low bus utilization ratios, equipment downtime, an underdeveloped workforce, and diverse stakeholder interests and priorities.

The research team seeks to overcome these hurdles with a holistic approach that includes the integration of intelligent technology development with community needs. Sustainability and transportation access will be focal points in their research and solution design. 

The project will involve the development of intelligent tools for effective and data-driven decision-making regarding bus electrification. The project will also assess collaborative governance in public bus fleet electrification planning and policymaking. In addition, in collaboration with industry and community partners, the project will contribute to the development of a workforce to facilitate a sustainable future for electrified public bus transportation.

“Through these various activities, the project aims to support a scalable, transferable and sustainable path for bus electrification,” says Siddiki.

Siddiki co-authored a paper published in Renewable and Sustainable Energy Transition in August 2023 that presented findings on research related to the topic of transportation electrification. She and fellow writers examined pathways American cities with varying degrees of plug-in electric vehicle (PEV) adoption and policy activity took to encourage PEV adoption in the late 2010s. They found that transportation electrification in cities was streamlined through the work of PEV advocates that collaborated across sectors.

This recent work builds on previous projects that Siddiki has conducted examining public sector policies to encourage electric vehicle adoption as well as factors informing individual vehicle uptake.

Siddiki is the Chapple Family Professor of Citizenship and Democracy and director of the master of public administration program and the Center for Policy Design and Governance. Her research focuses on policy design, collaborative policymaking, institutional theory and analysis, and regulatory implementation and compliance.

“Professor Siddiki’s leadership of the Center for Policy Design and Governance and her broader interdisciplinary work, collaborations and scholarship elevates the visibility and relevance of the research being done as well as the diverse audiences that are impacted by the outcomes and the external funding being prioritized to support evidence-based policy and implementation,” says Dean David M. Van Slyke.

The project research team is led by principal investigator Jie Xu of George Mason University. In addition to Siddiki, it also includes Wenying Ji, Ran Ji, Vivian Motti, David Wong and Fengxiu Zhang—all of George Mason University, and Jundong Li of the University of Virginia.
