Rolling Resistance and Vehicle Efficiency

Mark Hoffman, an assistant professor of mechanical engineering at Auburn University, and his graduate research assistant Karl Bohnenberger have been studying one of the lesser known contributors to poor fuel economy: rolling resistance. Rolling resistance is a measure of the effort required to keep a tire rolling. It might not grab headlines, but rolling resistance has a substantial impact on emissions and energy use. According to the US Department of Energy, conventionally fueled vehicles use up 11% of their fuel to keep their tires rolling, while electric vehicles use up to 25% of their energy for this purpose. As a result, reducing rolling resistance, as well as quality research on the subject, presents a valuable opportunity to improve vehicle efficiency and reduce the transportation sector’s carbon footprint. On this episode of AASHTO’s ETAP Podcast, Mark and Karl join us to chat about rolling resistance reduction as an attainable step toward a sustainable future.

Monarch Butterfly Conservation with Arizona DOT’s Kris Gade

Once ubiquitous in North America, the monarch’s striking orange and black wings are likely the first image that comes to mind when picturing a butterfly. The monarch is famed not only for its beauty, but also for its role in a healthy ecosystem – the pollinators are a critical support to some uniquely American landmarks: from the Great Smoky Mountains to Zion National Park. Yet, over the past few decades, the monarch has experienced a dramatic dip in population.

As the eastern members of this iconic species prepare for their annual migration to Mexico, on this episode of the AASHTO ETAP Podcast we talk with Arizona Department of Transportation’s Roadside Resource Specialist, Kris Gade, Ph.D — one of the professionals leading the charge for monarch conservation.

Roadside Vegetation & The Ray

In this month’s episode of AASHTO’s ETAP Podcast, host Bernie Wagenblast sits down with Matthew Quirey, a Landscape Design & Research Fellow at The Ray. For his thesis, Matthew partnered with The Ray to produce new classifications of the most beneficial and well rounded roadside vegetation systems which can now be used to guide Georgia’s efforts in sustainability and harmonious roadside ecology.

Connecticut DOT Climate Initiative Program and Partnership with Department of Environmental Protection

This month’s AASHTO’s ETAP Podcast will focus on how state agency partnerships are helping Connecticut both achieve its state climate goals and implement the Transportation and Climate Initiative Program, or TCI-P. State DOTs are critical stakeholders in deciding how to re-invest revenue generated caps on emissions. TCI-P is a historic multi-state effort to cap and reduce greenhouse gas emissions from transportation In Connecticut, for example, TCI-P is projected to generate roughly a billion dollars over the next decade, much of which will support transportation systems.

To learn more about TCI-P and the ongoing collaboration between state agencies in Connecticut, we are joined by Katie S. Dykes, the Commissioner of the Department of Energy and Environmental Protection, or DEEP, as well as Garrett Eucalitto, the Deputy Commissioner of the Connecticut Department of Transportation.

Manual on Uniform Traffic Control Devices: Looking Back, Looking Forward with Jeff Lindley, PE, ITE Chief Technical Officer

The Manual on Uniform Traffic Control Devices (MUTCD) from the Federal Highway Administration (FHWA) has been around for nearly 100 years, and is the federal standard for regulation of all things signs, markings, and signals in the US transportation system. But how has the manual changed throughout the years, and how has ITE played a role in influencing those changes? ITE Deputy Executive Director and Chief Technical Officer Jeff Lindley joins the podcast to demystify these issues. He also describes ITE’s response to the current Notice of Proposed Amendments issued by FHWA, which is expected to result in a new edition of the manual, the first to be issued since 2009.

Transportation Equity and Minnesota’s Rethinking I-94 Project

This episode of the AASHTO ETAP podcast will focus on transportation equity and environmental justice. Transportation systems are critical to people’s ability to reach jobs, educational opportunities, health care, and a number of other goods and services. However, underserved and marginalized communities often lack transportation options that are accessible and affordable. In its efforts to address these issues, the Minnesota Department of Transportation has earned national recognition for its Rethinking I-94 project. MnDOT began the project in 2016, working with communities negatively affected by the construction of I-94 in the 1960s to develop a new vision for the Minneapolis–Saint Paul area. MnDOT Commissioner Margaret Anderson Kelliher and Rethinking I-94’s Livability Director, Gloria Jeff, join us on this episode to discuss transportation equity and environmental justice.
