Latest CTR Research: Brakewood Named Associate Director of T-SCORE, new Tier 1 UTC

CEE Assistant Professor Candace Brakewood is an Associate Director of a new University Transportation Center (UTC) led by Dr. Kari Watkins at Georgia Tech. This UTC will investigate recent declines in public transit ridership. UTK joins researchers from Georgia Tech’s departments of civil and environmental engineering and industrial engineering as well as the University of Kentucky and Brigham Young University. The team was awarded a $1 million grant from the U.S. Department of Transportation and is one of four new Tier 1 UTCs established in 2020 to address critical transportation challenges in the US. This new consortium is dubbed the T-SCORE Center (Transit-Serving Communities Optimally, Responsively, and Efficiently), and it will use a two-track research approach. The Community Analysis Track, which is being led by Brakewood and includes CEE Professor Chris Cherry, plans to assess recent ridership trends, identify markets most effectively served by transit, and evaluate transit’s ability to respond to a changing environment. This work takes on new urgency in light of the impact of the Covid-19 pandemic on transit ridership and will include recovery strategies for a post-pandemic reality.

CTR Welcomes Interim Leadership

David Clarke
Jerry Everett
DeAnna Flinchum

David Clarke retired as the director of the Center for Transportation Research (CTR) at the end of 2020 after 12 years of leadership. On January 1, after serving as the center’s associate director for the last eight years, Jerry Everett stepped in as the new interim director, and DeAnna Flinchum assumed the role of interim associate director. The two will lead CTR through much, if not all, of 2021. More…


How CTR Makes a Difference

Motorcyclist fatalities are 25 to 30 times greater than those of other drivers, in terms of miles traveled. Asad Khattak (CEE) wants to understand the variables that correlate with motorcycle crashes and injuries. His study analyzes a unique database of motorcycle crashes collected from the federally sponsored Motorcycle Crash Causation Study to explore how key risk factors vary by demographics and from one context to another. Motorcyclists represent a segment of vulnerable road users that have very high levels of risk mostly because of their lack of protection when involved in a crash. Read research brief…; read paper published in Accident Analysis & Prevention…

Dr. Airton Kohls collaborated on recent research by the USDOE’s National Renewable Energy Laboratory in partnership with ORNL and the city of Chattanooga to deploy real-time traffic signal control strategies based on data from GPS devices, vehicle sensors, and visual analytics used to examine the underlying causes of congestion. Kohls provided traffic signal expertise during the Shallowford Road remote testing design procedures, validation, and multi-day test monitoring. CTR will continue to be a partner on phase 2 of this project that explores a regional approach to traffic signal control optimization.

Each year CTR conducts a statewide observational survey of seat belt use for the Tennessee Highway Safety Office. CTR researchers are currently traveling across the state to visit 190 designated observation sites in 16 counties. Survey results determine the state’s official seat belt use rate, which influences funding for occupant protection programs and guides highway safety education, outreach, and enforcement efforts in the following year. In 2019, this survey documented the seat belt use of more than 34,000 vehicle occupants and found that Tennessee’s belt use rate reached an all-time high at 91.75%
