White Paper

This paper analyzes evidence on the economic benefits of placemaking efforts that prioritize pedestrian and non-motorized access and that, at times, reduce vehicle miles traveled.

This white paper provides a guide for practitioners on how to read, understand, and use results reported in this especially challenging area of the literature: the relationship between the built environment, the transportation system, and driving.

Researchers developed a framework to identify the range of possible travel effects, both positive and negative, on users of ride-hailing services.

This white paper summarizes the state-of-knowledge and state-of-the-art in pavement life cycle assessment modeling, with particular emphasis on life cycle greenhouse gas emissions and on interpretation and analysis that lead to GHG reductions from the on-road transportation sector.

This paper explores opportunities for the redevelopment of failing regional shopping malls as Transit-Oriented Developments (TODs) to improve transit ridership, focusing on Southern California.

In this white paper, the available evidence on the travel and environmental effects of automated vehicles is critically reviewed to understand the potential magnitude and likelihood of estimated effects.

This white paper focuses on (actual and potential) users of systems of electrically-powered, shared, and automated vehicles (e-SAVs) as well as other road-users, e.g., pedestrians and cyclists. The role of user perceptions of safety and security are reviewed to create an initial framework to evaluate how they may affect who will initially use systems of e-SAVs for personal mobility and how safety and security will have to be addressed to foster sustained transitions.

This white paper provides an overview, synthesis, and critical assessment of academic research and transportation planning practice in order to provide a shared foundation for the many parties working toward equitable transportation systems.

This study analyzes travel behavior in relationship to sociodemographic changes.
