Distributive justice impact assessment using activity-based modeling with path retention

Research Product Type

Dissertation / Thesis

The research objectives of this dissertation are to develop a modeling framework within an advanced activity-based travel demand model that can be used to assess the distribution of transportation cost and benefits across communities of interest and implement a data structure and variable tracking system that can be implemented within and across various modeling tools to ensure that data needed for equity assessment transfer between models, and that outputs from combined models can be used to assess equity impacts.

This policy brief summarizes findings from research that compared results from the NCST Induced Travel Calculator to the induced travel analysis completed for five highway expansion projects' actual environmental impact assessments.

Envisioning Micromobility as Public Transit: Two intervention studies in the living lab of Davis, California

Principal Investigator Kari E. Watkins, Ph.D.
University of California, Davis

To begin to envision micromobility as serving existing public transit and acting as public transportation itself, the researchers will examine the role of pricing on micromobility demand. In this project, the researchers will conduct two pricing-focused field experiments, partnered with the micromobility operator, SPIN, and a railway operator, Capitol Corridor.

Research Report

What factors could work as facilitators or barriers in their willingness to adopt microtransit? Who are the early adopters of microtransit? Guided by the theory of planned behavior, this study aims to fill the gap in knowledge by conducting a large-scale survey of microtransit adopters and users of other means of transportation in the Sacramento area of California in 2021.

Factors Affecting Passenger Travel Demand in the United States and Their Potential Impacts on Transportation in the 21st Century

This presentation discussed recent trends in short-distance trips and changes in travel demand observed in the United States, the factors behind these trends, and how these factors are likely to affect travel demand in future years.

Research Report

This study developed a parking simulation in SUMO following a set of parking behaviors (e.g., parking search, parking with off-street parking information availability, double-parking). These scenarios were tested in three different (land use-based) sub-study areas representing residential, commercial and mixed-use.
