Connected Vehicle System Design For Signalized Arterials, Xianfeng Terry Yang, Mingyue Ji, Qinzheng Wang

TREC Final Reports

It can be expected that connected vehicles (CVs) systems will soon go beyond testbed and appear in real-world applications. To accommodate a large number of connected vehicles on the roads, traffic signal control systems on signalized arterials would require supports of various components such as roadside infrastructure, vehicle on-board devices, an effective communication network, and optimal control algorithms. In this project, we aim to establish a real-time and adaptive system for supporting the operations of CV-based traffic signal control functions. The proposed system will prioritize the communication needs of different types of CVs and best utilize the capacity of the …

Understanding Economic And Business Impacts Of Street Improvements For Bicycle And Mobility – A Multicity Multiapproach Exploration, Jenny H. Liu, Wei Shi

TREC Final Reports

Many cities across the country, as part of Complete Streets initiatives or to promote community livability and environmental sustainability, have engaged in street improvement or transportation infrastructure upgrade projects that increase access and mobility for pedestrians and bicyclists through a reduction of on-street parking or traffic lanes. With various transportation modes competing for scarce resources (including right-of-way and transportation funding), city planners and transportation agencies often struggle with how to justify these infrastructure investments for non-motorized modes such as bicycling and walking, particularly when driving is still the predominant mode of transportation in most cities. There is a vital need …

The Impacts Of The Bicycle Network On Bicycling Activity: A Longitudinal Multi-City Approach, Wei Shi

Dissertations and Theses

Bicycling is a promising approach to improve health, environment, and economic development of urban places. Theoretically, a bicycle network's component goes beyond lanes and paths, and would generate greater impacts than the sum of its parts. However, most previous research focused on how individual types of bicycle-related infrastructure could promote bicycling. Few empirical studies investigated how bicycle networks impact bicycling activity. This project attempts to address this question. Specifically, how to properly measure bicycle networks, and what impacts bicycle networks have on bicycling activity, e.g. bike ridership and bike mode choice, across different cities and longitudinally.

To address the first …

Visualizing Statewide Trips: Tools To Leverage Gps Data In Transportation Planning, Nikola Markovic

TREC Project Briefs

The University of Utah has a new data visualization service to offer to state DOTs and other agencies. Using Small Starts funding from the National Institute for Transportation and Communities (NITC), researcher Nikola Markovic and his team have developed a suite of visual analysis tools to demonstrate how GPS trajectory data can help accurately model and analyze mobility trends. These data are typically purchased from vendors, which means that transportation agencies must first understand the benefits before they decide to invest in data acquisition.

Visual Exploration Of Utah Trajectory Data And Their Applications In Transportation, Seth Miller, Zachary Vander Laan, Yinhu Wang, Nikola Markovic

TREC Final Reports

Transportation agencies have an opportunity to leverage massive GPS trajectory data to support their analyses and enhance their decision making. However, these data are typically purchased from vendors, which means that transportation agencies must understand their benefits before they decide to invest in data acquisition. To help transportation agencies better understand the tremendous value of trajectory data, the PI of the project acquired Utah GPS trajectory data from one of the leading GPS data providers and conducted visual analyses demonstrating applications of trajectory data in various areas of transportation. The analyses focused on (a) evaluating the data itself by exploring …

Webinar: New Travel Demand Modeling For Our Evolving Mobility Landscape, Reid Ewing, Sadegh Sabouri

TREC Webinar Series

Conventional four-step travel demand models are used by nearly all metropolitan planning organizations (MPOs), state departments of transportation, and local planning agencies, as the basis for long-range transportation planning in the United States. A flaw of the four-step model is its relative insensitivity to the so-called D variables. The D variables are characteristics of the built environment that are known to affect travel behavior. The Ds are development density, land use diversity, street network design, destination accessibility, and distance to transit. In this seminar, we will explain how we developed a vehicle ownership model (car shedding model), an intrazonal travel …

When Growth Outpaces Infrastructure: Access To Opportunities In Suburban Boomtowns, Jandel Crutchfield, Courtney Cronley, Kate Hyun

TREC Project Briefs

In the last twenty years, the population increased over 100% in Collin County, Texas. The county is projected to have over 2.4 million residents by 2050 -- more than three times its population in 2010. When enough people flock to an area to call it a boomtown, the population tends to grow much faster than the infrastructure to support it. Where does that leave mobility options for residents? Researchers from the University of Texas at Arlington’s (UTA) School of Social Work and College of Engineering partnered with the Collin County Homeless Coalition (CCHC) to investigate gaps in transportation services and …

Harmonizing Climate Change Mitigation And Adaptation In Transportation And Land-Use Planning In California Cities, Serena E. Alexander, Asha Weinstein Agrawal, Ashley M. Hooper, Michael R. Boswell

Mineta Transportation Institute

Abstract: Recent extreme weather events in California—wildfires, drought, and flooding—make abundantly clear the need to plan effective responses to both the causes and the consequences of climate change. A central challenge for climate planning efforts has been identifying transportation and land-use (TLU) strategies that simultaneously reduce greenhouse gas emissions (“mitigation”) and adapt communities so that they will be less affected by the adverse impacts of climate change (“adaptation”). Sets of policies that collectively address both mitigation and adaptation are known as “integrated actions.” This study explores municipal climate planning in California to determine whether cities incorporate integrated actions into their …

Covid-19’S Effects On New York City’S Food System: Lessons For Public Health Responses, Nevin Cohen, Nicholas Freudenberg

Publications and Research

The COVID-19 pandemic disrupted food availability and affordability and changed the daily food practices of New Yorkers. Eleven surveys of samples of 1,000 New York City adults from March 13 through June 28 illustrate three effects on food access and food insecurity: (1) closing restaurants, schools, and other sources of prepared foods reduced access and changed shopping patterns, food expenditures, and diets; (2) economic disruption exacerbated food insecurity and increased demand for food assistance; and (3) altered food practices affected diets and health. These impacts were disproportionately borne by vulnerable populations. This paper reports survey responses illustrating the effects of …

A Backbone Organization For Denver Based Environmental Justice Organizations 5280 For Environmental Justice, Allison Finnegan-Kihega

Regis University Student Publications (comprehensive collection)

Environmental injustices in Denver follow the same patterns that are seen throughout the country, which is that low-income People of Color are, relative to White people, disproportionately impacted by poor air and water quality, food deserts, displacement, and a phenomenon known as urban heat islands. The literature review conducted for this proposal revealed that despite the 2019 U.S Census Bureau indicating that Denver is 80.9 percent White, 29 percent Latino, and 10 percent Black, neighborhoods with predominantly Black and Latino residents are the neighborhoods experiencing environmental injustices in Denver.

For this project proposal, a literature review was conducted along with …

Families Belong Together: The Path To Family Sanctity In Public Housing, Mckayla Stokes

Northwestern Journal of Law & Social Policy

In its 2015 landmark civil rights decision in Obergefell v. Hodges, the Supreme Court finally held that the Equal Protection and Due Process Clauses of the United States Constitution guarantee same-sex couples’ marital equality. The Court’s unprecedented declaration that the right to marry is a fundamental right under the Due Process Clause strengthened married couples’ right to privacy because it subjects government actions infringing on marital unions to heightened scrutiny. The Supreme Court has the option to minimize the impact of Obergefell by interpreting the right to marriage very narrowly—as only encompassing the right to enter into a state-recognized union …
