Behavioral Experiment to Simulate AV Impacts on Travel Patterns: The “Chauffeur” Experiment

#Shared Mobility #Automation

This project seeks to understand the changes in travel behaviors as the subjects adjust their travel and activities during the chauffeur week when, as in a self-driving vehicle, they are explicitly relieved of the driving task.

Travel Patterns of Transportation Network Companies (TNCs) Drivers and Impacts on Transportation Demand

#Shared Mobility

This project will investigate the travel behavior and choices of TNC drivers and riders using recently-collected travel diary data.This project will investigate the travel behavior and choices of TNC drivers and riders using recently-collected travel diary data.

Investigating the Influence of Dockless Electric Bike Share on Travel, Behavior, Attitudes, Health, and Equity

#Shared Mobility #Electrification #Micromobility

The goal of this study is to examine the travel behavior and attitudes of users and non-users of SACOG’s new dockless electric-bike share system.

Can we Design SAV so People are More Willing to Ride-Pool?

#Shared Mobility #Automation

This research develops an online survey protocol to test potential SAV users’ willingness to ride-pool in a conventionally designed vehicle versus one with features aimed to mitigate risks and create benefits for pooling.

International Survey of Ridehailing Use and Shared Mobility in Four Metropolitan Areas of Developing Countries: Beijing, Mexico City, Mumbai and Sao Paolo

#Shared Mobility #International

This project aims to explore the factors affecting the adoption and frequency of ride-hailing service usages in growing metro areas of four selected developing countries.

Shared Transportation Services International Survey

Emissions Impact of Connected and Automated Vehicle Deployment in California

#Automation

This project evaluates potential future scenarios of deployment of light-duty connected and automated vehicles (CAV) on vehicle miles traveled (VMT), energy usage, and greenhouse gas (GHG) and criteria pollutant emissions in California.

Modeling 3 Revolutions Futures (in cooperation with Energy Futures)

#Automation #Electrification #Shared Mobility

This annual report develops scenarios of future global shifts in patterns, technologies and fuels, and estimate their impacts on costs and CO2 emissions.

AV Scenarios in the San Francisco Bay Area: Simulation of System-Level Travel Effect Using Agent-Based Demand and Supply Models in San Francisco Bay Area

#Automation

This project explores system-level travel effects under several automated vehicle scenarios using agent-based travel demand and supply models.

Electrifying TNCs (in cooperation with Plug-in Hybrid and Electric Vehicle Center)

#Electrification #Shared Mobility

This study examines electric vehicle use in new mobility service fleets using novel datasets from both transportation network companies and charging service providers.

Surveys of Potential AV riders in UC Davis West Village Before and After the Introduction of an Autonomous Shuttle (in cooperation with China Center of Energy and Transportation)

#Automation #Shared Mobility

This before-and-after study surveys the public attitude, facilitators and barriers of an autonomous shutter's adoption, as well as potential market and influences of future AVs.

Car-Sharing and AV Testing in Dubai

#Automation #Electrification #Shared Mobility

This project focuses on the analysis of the mobility patterns in The Sustainable City (TSC), a sustainabilityinspired environmental-friendly community in Dubai (partially inspired by the UC Davis West Village), and the investigation of the market for an EV-carsharing program to be developed in the community and the travel behavior impacts of the deployment of a driverless shuttle.

Disruptive Transportation

#Shared Mobility

Ride-hailing services have experienced significant growth in adoption since the introduction of Uber, in 2009. Although business models to support the sharing of vehicles (e.g., carsharing) have been present in the United States for more than 15 years, their adoption has been somewhat limited to niche markets in dense, urban cities or college campuses.
