Identifying Bikeshare Station Locations to Improve Underserved Communities’ Accessibility

Research Product Type

Policy Brief

This study examines whether bikeshare systems have targeted specific populations and quantitatively assesses the potential for bikeshare systems to provide greater accessibility for underserved communities.

If pooling with a discount were available for the last solo-ridehailing trip, how much additional travel time would users have accepted and for which types of trips?

Principal Investigator Yongsung Lee, PhD
Georgia Institute of Technology

Findings and implications from this research will inform planners and policymakers of effective measures for the promotion of pooled ridehailing and other sustainable travel behaviors.

If Pooling with a Discount were Available for the Last Solo-Ridehailing Trip, How Much Additional Travel Time Would Users Have Accepted and for Which Types of Trips?

Research Product Type

Research Report

This research explicitly models taste heterogeneity towards pooled ridehailing. In addition, unlike existing studies either at the person level or employing stated-preference data, a trip-level analysis is performed in connection with revealed preferences, which generates more realistic and relevant implications to policy and practice.

Impact of Shared Mobility Services on Passenger Travel

Principal Investigator Giovanni Circella, Ph.D.
Georgia Institute of Technology

Impacts of Connected and Automated Vehicles on Travel Demand and Emissions in California

Research Product Type

Associated Publication

This study helps understand how the anticipated emergence of CAVs will affect various aspects of society and transportation, including travel demand, vehicle miles traveled, energy consumption, and emissions of greenhouse gases and other pollutants. The research team designed a set of future system configurations under the California Statewide Travel Demand Model framework to simulate scenarios for the deployment of passenger CAVs in California by 2050.
