Investigating Transportation Decarbonization through Transit and Rideshare Electrification: A Scenario Analysis with Large-Scale Models

  • Principal Investigator Mehdi Azimi, Ph.D.
  • Texas Southern University
This project utilizes the Department of Energy's Systems and Modeling for Accelerated Research in Transportation (SMART) workflow to evaluate potential outcomes of electrification policies, specifically for transit and rideshare systems. This will be accomplished by harnessing a large-scale agent-based activity-based transportation modeling tool designed for the Houston Metropolitan Area.

Investigation of the Abilities and Limitations of Travel Demand Modeling in Informing Decision-Making

  • Principal Investigator Susan Handy, Ph.D.
  • University of California, Davis
This project will investigate the capabilities and limitations of Travel Demand Models by delineating their ability to accurately forecast project outcomes and determining how susceptible model analyses are to bias. The findings inform policymakers of the opportunities and limitations in relying on TDMs as regulatory tools.

Modeling multi-modal network equilibrium with active transportation and shared mobility

Research Product Type
Dissertation / Thesis
This study models the active transportation and vehicular travel traveling modes in a multi-modal network problem taking into account TNC services, such as, e-hailing, e-pooling, and express pool. The objective is to analyze passengers' choices among active transportation, solo driving, and TNC services, considering various trade-offs related to health, monetary, time, and inconvenience costs, and their subsequent impacts on traffic network performance.

Modeling Traffic Noise and Light on Natural Landscapes at the State Scale

  • Principal Investigator Fraser Shilling, Ph.D.
  • University of California, Davis
The researchers will develop a method for statewide modeling of noise and light intrusion into areas adjacent to roads to aid locating and designing crossings to maximize wildlife approach and use.
