A Deep Dive into Corridor DC Fast Chargers in California

Research Product Type
Dissertation / Thesis
This dissertation focuses on the complex nature of the cost drivers of corridor direct current fast chargers (DCFCs) along major transportation corridors and aims to better understand charger reliability in the context of DCFCs. It also explores the level of reliability that is desirable in the context of drivers.

A framework for optimizing public transit fleet conversion to alternative fuels

Research Product Type
Dissertation / Thesis
This study develops an analytical framework to automatically generate optimal plans for fleet operations and conversion based on fleet-specific characteristics. The goal of the framework is to allow agencies to minimize the fleet-wide energy use, life-cycle CO2 emissions, and/or economic costs when transitioning to alternative fuels.

Accelerate Plug-in Electric Vehicles adoption via understanding household adoption decisions and designing sustainable transportation finance policies

Research Product Type
Dissertation / Thesis
This dissertation sets out to 1) explore the feasibility of implementing a per-mile road-usage charge (RUC) in replacement of the motor fuel taxes, 2) estimate the changes in vehicles-miles travelled (VMT) and the revenues generated from motor fuel taxes under the backdrop of vehicle electrification, and 3) quantify the effects of vehicle class and fuel type portfolios in ZEV-adopting households’ vehicle replacement decisions.
