Research Report

This study extends the analysis from early plug-in electric buyers to the population of new-car buyers (of whom the vast majority own gasoline powered internal combustion engine and hybrid electric vehicles in California.

This work is the first to examine households’ decision to maintain at least two plug-in electric vehicles (PEVs) in their household fleets.

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 study examines climate action plans (CAPs) released by jurisdictions in California, and develops a framework to assess their inclusion, which could also be used to guide future CAP development, and develops a set of guiding questions to promote the inclusion of equity themes in climate action planning and implementation.

The goal of this project was to assess the capabilities of the travel demand forecasting models (TDMs) used by California’s metropolitan planning organizations (MPOs) with respect to forecasting the increase in vehicle miles of travel induced by highway capacity expansion.

The objective of this research was to determine the possibilities for and barriers to the provision of battery charging infrastructure for heavy-duty electric trucks at roadside rest areas in California.

This study explored potential system-level travel effects of vehicle automation in the San Francisco Bay Area.

In this project, the researchers consider the issue of coordinating the parking decisions of a large number of long-haul trucks. More specifically, how to model the behavior of a region’s driver population and how it could be influenced.

This report focuses on the quickly evolving transportation patterns resulting from the adoption of ridehailing as part of the efforts accompanying the implementation of the Clean Miles Standard (CMS) regulation.

In the same efforts to understand the evolving travel-related activities and inform policymaking, the UC Davis 3 Revolutions Future Mobility Program conducted four waves of mobility surveys between Spring 2020 and Fall 2023. Key findings from the analysis of these data reveal that remote work and a combination of remote work and physical commuting (i.e., hybrid work) emerge as an enduring outcome of the pandemic.
