Projects - Sustainable, Safe Transport Planning and User Responses to Shocks in the System

Supervised Research Projects (as PI/Co-PI)

An exploratory analysis of commuting satisfaction and travel mode dissonance across the Commonwealth

Sponsor: Pennsylvania State University Exploration and Analysis Grants for Expanded Research (EAGER); Year: 2023-2024

Role: PI; Amount: $19,476

This project investigates travel decisions undertaken by commuters across the Commonwealth of Pennsylvania by scanning through Penn State's commuting population across all the campuses. In addition to understanding their travel mode choice and descriptive commuting characteristics, this study will investigate travel mode dissonance among Penn State commuters and its contributing factors. The study will also explore commuting satisfaction and the impact of this trip on subjective well-being.

Investigating Post-Pandemic Impacts on the Mobility of Transportation Disadvantaged Groups

Sponsor: Pennsylvania State University Graduate Research Experience and Training (GREAT); Year: 2023-2024

Role: PI; Amount: $43,915

This project investigates the changes in travel behavior, trip making, and activity participation levels of the transportation disadvantaged community members as they navigate the realities and after-effects of the COVID-19 pandemic.  

Understanding Geographic and Demographic Variation in Mode Choice and Travel Behavior

Sponsor: American Association of State Highway and Transportation Officials (AASHTO); Year: 2021-2022

Role: PI; Amount: $20,000

This project investigated the change in commuting trends (specifically on commute mode choice) across the United States of America through the lens of various geographic and demographic spheres. Results show that commute mode choice trends vastly vary across the country, and accurate determination of triggers/factors influencing commute mode choice is necessary for serving as inputs into planning and policymaking. 

Impact of COVID-19 on Travel Behavior and Shared Mobility Systems

Sponsor: National Center for Transit Research (NCTR, USDOT); Year: 2020

Role: PI; Amount: $26,888; Report

This project investigated the impact of COVID-19 on activity participation, trip making, and travel behavior using a nationwide stated preference survey that was disseminated by the PI. Analysis of the survey revealed the multitude of ways in which COVID-19 had impacted travel behavior, including residential location, vehicle purchase, telecommuting, trip making, and activity participation. Results also revealed how consumer preferences would alter regarding the use of shared mobility systems, considering the threat posed by the global health pandemic.

Measuring Transportation Network Performance During Emergency Evacuations: A Case Study of Hurricane Irma and Woolsey Fire

Sponsor: Center for Transportation, Equity, Decisions and Dollars (CTEDD, USDOT); Year: 2019-2020

Role: PI; Amount: $30,000; Report

This project investigated the impact of two events – Hurricane Irma and Woolsey Fire on the transportation network performance in Florida and California. Large-scale evacuation data triggered by these two events were collected, and roadway performance metrics created by the project team were used to characterize the performance of the roadway network. Investigations revealed several insights on roadway utilization, bottlenecking in otherwise normal conditions, and the impact of a no-notice event (such as a wildfire) on evacuation patterns that were quite different from those triggered by a short-notice event such as a hurricane. The results from this effort serve as key lessons for state agencies at the forefront of disaster planning and evacuation management.

Measuring the Impact of Florida Scenic Highway Designation

Sponsor: Florida Department of Transportation (FDOT); Year: 2019-2020

Role: Co-Investigator; Amount: $100,000; Report

This project created a spreadsheet-based tool for estimating the economic impact of Florida’s scenic byways on Florida’s economy. The input data for this effort was curated using a stated-preference agency survey that elicited information on a variety of aspects from each scenic byway to accurately reflect their contribution to Florida’s economy.

Research Projects as Task Lead

Utilizing Artificial Intelligence with Vision-based Systems for Monitoring Trespassing – Best Practices I

Sponsor: Federal Transit Administration (FTA); Year: 2021; Report

Reviewed global AI/ML and vision-based approaches that have been used by agencies in multiple sectors, including transportation, for monitoring and security. Prepared a stated preference survey aimed at AI/ML and vision-based experts to understand existing best practices across multiple sectors to be incorporated into monitoring railroad trespassing. 

Scenario Analysis of Future Roadway Network of Tampa Bay Area

Sponsor: Florida Department of Transportation (FDOT); Year: 2020-2021

Conducted scenario analysis for converting an existing freeway into a boulevard including traffic impact, GIS-based crash, and air quality/equity analysis.

Wrong-Way Driving Solutions, Policy, and Guidance: Phase 1

Sponsor: National Cooperative Highway Research Program (NCHRP); Year: 2020-2021

Literature review, and data analysis support on evaluating wrong way driving solutions and providing policy and guidance to state agencies and other stakeholders.  

Mitigation for Trespasser and Suicide Fatalities and Injuries

Sponsor: Federal Transit Administration (FTA); Year: 2020; Report

Literature review, design and development of agency outreach surveys, follow-up case studies, and data analysis support on identifying strategies and best practices to reduce/mitigate trespasser suicides and fatalities on railroads.  

Air Pollution and Equity Impacts of Proposed Freeway Expansion from a Health in All Policies Perspective

Sponsor: Center for Transportation, Environment, and Community Health (CTECH, USDOT); Year: 2018-2020; Report

Design and development of a qualitative data collection instrument, stakeholder interviews, and qualitative analysis support on understanding air pollution and equity impacts of Tampa Bay Next (TB Next) project on project stakeholders. 

Florida Aviation Activity Forecast Methodologies and Tools Development

Sponsor: Florida Department of Transportation (FDOT); Year: 2017; Report

Assisted FDOT in the development of newer, more accurate forecasting tools and methodologies for estimation aviation activity (passenger enplanement as well as fleet estimations) on commercial as well as general aviation airports.   

Understanding Consumers’ Perceptions, Intended Adoption, and Anticipated Travel Behavioral Impacts of Autonomous Vehicles

Sponsor: University of South Florida (USF); Year: 2013-2017; Report

Design and development of multiple stated-preference surveys on understanding consumers’ perceptions, attitudes, preferences, and intentions to adopt autonomous vehicles; Also, investigations into the impact of autonomous vehicles on travel behavior and trip making. Led data analysis and econometric modeling efforts.  

Evaluation of Logistics-Led Economic Development in Florida 

Sponsor: Florida Department of Transportation (FDOT); Year: 2015-2016; Report
