This work aims to advance the role of hydrogen energy in California, and assist in achieving California's goal of carbon neutrality by 2045, through utilizing an optimization-based modeling approach to help design infrastructure systems for hydrogen.
This study aims to conduct a time-series to explore how electric vehicle (EV) adoption has increased over time and to predict how future EV adoption will continue to expand in the future.
This study explores how has EV adoption increased over the past years and predicts how will the EV market continue to expand and penetrate in the future years using a case study with regional granular travel survey data.
In this project, the research team will assess the impacts of discounted express lane tolls on ZEV adoption statewide and specifically in disadvantaged communities and areas where these discounts will have the largest impact. The results of this analysis will be used to propose a discount system that will encourage ZEV adoption but not overly burden express lane infrastructure.
This report assesses the potential use of express lane discounts as a driver of zero-emission vehicle adoption by testing the effectiveness of a range of discount scenarios. The researchers find that providing even very large discounts for express lane usage to zero-emission vehicles would only slightly increase vehicle sales but would make these lanes much less capable of serving their other purposes. As part of this project, an Excel tool was developed that allows users to test their own scenarios.
This project concentrates on policy-focused research supporting the design and implementation of medium- and heavy-duty zero-emission vehicle policies with a team of researchers from UC Davis' Institute of Transportation Studies. The study focuses on policy considerations for increasing fleets’ share of ZEVs' purchases.
In this study, researchers from the University of Southern California investigated the adoption of battery electric heavy-duty trucks (BEHDTs) in the short-haul freight movement sector and the drayage industry.
Learn about the Zero Emission Vehicle (ZEV) Planning Tool that has been developed to maximize California Department of Transportation’s (Caltrans) statewide deployment of ZEV’s.
This policy brief summarizes findings from a study that developed six alternative fee structure scenarios, each capable of raising $200 million per year, to explore equity implications of a fee system in California.
In this briefing, researchers from the National Center for Sustainable Transportation will share insights from electric vehicle markets in two very different states. Insights on successful incentives, adoption barriers, and policy gaps from these states provide valuable lessons learned for federal efforts to promote a cleaner transportation system.
