Projects

Texas Southern University, in partnership with the University of Houston, will expand the Texas Department of Transportation’s Transportation Asset Management Plan which currently only includes pavements and bridges.

This study aims to compare the feasibility of battery electric and hydrogen fuel cell powertrains for concrete mixer trucks to determine which is the better zero-emission powertrain for the industry to transition towards.

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.

The purpose of this project is to explore the induced travel effects of categories of roadway expansions not currently covered by the Induced Travel Calculator, including minor arterials, interchanges, on- and off-ramps, and non-general-purpose facilities.

This project will develop guidance for evaluating sociodemographic disparities from the impacts of State Highway System expansion projects and associated vehicle miles traveled (VMT) mitigation strategies.

This project seeks to uncover to what extent factors like the convenience of remote activities, hybrid work schedules, and tech-savviness influence residential and travel choices.

This project will conduct a literature review and expert survey to investigate the most promising emerging technologies for advanced speed management, such as Connected and Autonomous Vehicle technologies, Advanced Driver-Assistance System messaging, Advanced Traveler Information Systems, Advanced Vehicle Location, remote sensing and detection technologies for pedestrians, bicycles, and other vulnerable users; advanced signal timing technologies, etc.

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.

With increasing electric vehicle (EV) demand, EVs have entered the international second-hand (SH) vehicle market, risking economic and environmental burdens through spent batteries. This research addresses challenges associated with the EV transition in North America.

This research will help policymakers understand the obstacles faced by socially vulnerable populations in accessing healthy food, whether those obstacles involve transportation access or awareness.

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.

This dissertation will develop a representative synthetic population of California including household and vehicle variables crucial to modeling electric vehicle (EV) adoption and equity.

This research will address the urgent need for decarbonization in marine ports and the establishment of green shipping corridors to mitigate emissions and enhance environmental sustainability.

In this study, the researchers will measure the gaseous emissions from the off-gassing of tires during laboratory and real-world testing conditions. The researchers will also evaluate the secondary organic aerosol forming potential from the off-gassing of tires during only laboratory conditions using state-of-the-art instrumentation.
