Research

My research deals with the application of economic and statistical methods to improve our understanding of the relationship between transport systems and economic development. My project portfolio covers these main areas of research:

  1. Infrastructure Investment and Economic Development – I focus on the theoretical and empirical modeling of the linkages between transportation infrastructure investments and individual and firm behavior.
  2. Travel Behavior, Land Use and Urban Form I am interested in the theoretical modeling of the relationship between urban form, residential location and travel patterns. I develop empirically implementable models that define how household travel behavior responds to changes in urban form.
  3. Transportation Demand Management (TDM) – I focus on developing and implementing standardized methods to quantify the societal costs and benefits of congestion-reduction strategies with a focus on energy conservation. My focus is on the design and implementation of practitioner-oriented applications.
  4. The Economic and Social Consequences of Connected and Autonomous Vehicles – I am interested in the evaluation and performance assessment of connected and autonomous vehicles in terms of safety, mobility, economic productivity, energy and environmental benefits.

The underlying interest in these areas is in providing scientific investigation to evaluate mechanisms supporting livable and sustainable communities.  Below is a summary of selected projects where I have or had a direct involvement as a Principal Investigator or Co-Principal Investigator.

  • Connected Vehicle (CV) Pilot Deployment Program (Co-Principal Investigator). Sponsored by the USDOT Intelligent Transportation Systems Joint Program Office (ITS JPO), the CV Pilot Deployment Program is a national effort to deploy, test, and operationalize cutting-edge mobile and roadside technologies and enable multiple CV applications. The objective of this project is to develop and implement the performance measurement and evaluation support plan (PMESP) at the Tampa Pilot, Florida.
  • Assessment of the Impacts of Streetcars and Other Urban Circulators (Principal Investigator).  Managing and coordinating comprehensive economic impact evaluation of 16 urban circulator and streetcar systems in the U.S. funded by the U.S. DOT Transportation Investment Generating Economic Recovery (TIGER) grant program.  The objective of this study is to determine if expenditures in urban circulator projects have a significant impact in creating and preserving jobs, increasing housing affordability, and improving occupation-household balance over time.
  • Variably Priced Carsharing Value Pricing Pilot Program (Co-Principal Investigator).  Established a carsharing program under a grant funded by the U.S. Department of Transportation Value Pricing Pilot Program.  Implemented and evaluated dynamic pricing mechanisms to reduce private vehicle use in favor of alternative, more sustainable modes.
  • Integrating Transit with Road Projects (Co-Principal Investigator).  Coordinated feasibility study to integrate transit services with road pricing strategies.  Explored multi-modal, public-private partnership mechanisms leading to improved utilization of the transportation infrastructure.
  • Estimating the Costs and Benefits of Emission Reduction Strategies (Principal Investigator).  Led development and implementation of TRIMMS (Trip Reduction Impacts of Mobility Management Strategies), a sketch-planning, spreadsheet-based application designed to evaluate travel demand management initiatives.  The model enables state and local agencies to conduct cost-benefit assessments of a broad range of emission reduction strategies for implementation of air quality plans and regional emissions analyses for transportation conformity purposes.
  • Economic and Community Benefits of Urban Fixed-Route Transit in Florida (Principal Investigator).  Conducted statewide economic impact analysis of mass transit system investments and operation.  The study focused on benefits to users and the general population in terms of reduced travel delays, improved reliability, improved traffic safety, and reduced emission of air pollutants.
  • Assessing the Economic and Business Impacts of the Proposed SR924 Parkway Extension (Principal Investigator).  Conducted economic impact and benefit analysis of implementing a limited-access, all-electronic tolling system.  Project considered the economic implications on lower income residents and local businesses located in a heavily urbanized area of Miami-Dade County, Florida.  Presented findings to local board meetings, public hearings, focus groups.
  • Monitoring the Implementation of Cleaner Fuels and Alternative Technologies for Florida Mass Transit Systems (Co-Principal Investigator).  Led the development of a life-cycle a cost comparison methodology to study the feasibility of alternative fuels for full size transit vehicles.  Provided policy recommendations to set a long-term course for the acquisition of cleaner vehicles.
  • Analysis of Freight Movement Mode Choice Factors (Co-Principal Investigator).  Produced a multi-modal feasibility study of domestic and international freight movements to identify strategic intermodal network constraints and opportunities.
  • The Economic Impact of Delaying Transportation Improvement Projects (Principal Investigator).  Led and coordinated a study to assess the opportunity costs of postponing infrastructure investments. The analysis provided policy-makers with guidance on timing and prioritization mechanisms to rank investment priorities.
  • Integrating Transit and Urban Form (Principal Investigator).  Led the development and formulation of an integrated approach to examining the relationships between transit design and land-use variables.  Produced policy guidance to identify transit-oriented development policies leading to increased transit patronage.
