Transportation and Public Health at the Crossroads: SMART Infrastructure to Improve Health Equity
The COVID-19 pandemic has disrupted the world, including how we view our transportation system. But that interruption in “the way we’ve always done things” has also provided us an unprecedented opportunity to take a step back and reassess our habits, systems and interactions to achieve healthier outcomes. One strategy to do so demands that transportation […]
Ocean of Possibilities — MarTREC Explores Blockchains for Maritime Industry
Endless waves. Cloud-dotted skies. Foaming wakes left by ships. Along the shore, ports bustle with activity, their efficiency in transporting international trade a key part of the U.S. economy. Intermodal carriers move freight inland from those ports, ultimately to stock store shelves and land on consumer doorsteps. The Maritime Transportation Research and Education Center (MarTREC) […]
NICR-Sponsored Study Evaluates Managed Lane Pricing Methods — Researchers Create New Measures for Comparing Pricing Strategies
Optimizing traffic flow is one goal of transportation agencies looking to improve mobility for transportation system users. Doing so reduces congestion, which not only optimizes roadway operations but also gets folks where they’re going faster while often improving safety. Managed lanes represent one method for achieving this, and many states have implemented them. Managed lanes […]
Teens in the Driver Seat® Holds 12th Annual Summit: Month-Long Gathering Honors Student Leaders Advocating Teen Driver Safety
The Texas A&M Transportation Institute’s (TTI’s) award-winning Teens in the Driver Seat® (TDS) program recognized teen advocates as champions of young driver safety at the 2021 TDS Safe Driving Summit held in May. Second only to teen suicide, car crashes kill more teens in the United States aged 15 to 18 than any other cause. […]
Over Three Decades of Leadership and Contribution: TTI’s University Transportation Centers
In 1987, the U.S. Congress authorized the U.S. Department of Transportation University Transportation Center (UTC) Program, establishing 10 federal regional UTCs across the country. The UTC Program was designed to improve transportation research in the United States by advancing technology and expertise across multiple modes of transportation while addressing vital workforce needs for the next […]
Shaking Up the System: Safe-D Looks at How Disruptive Technologies Can Improve Roadway Safety
Funded through the U.S. Department of Transportation’s University Transportation Center (UTC) Program, the Safety through Disruption (Safe-D) UTC is led by the Virginia Tech Transportation Institute (VTTI). In partnership with San Diego State University and the Texas A&M Transportation Institute (TTI), center researchers endeavor to maximize the potential safety benefits of disruptive technologies through targeted […]

The Last Stop with Greg Winfree: National Strategies, Local Expertise — The Evolution of the UTC Program Benefits Everyone
When the Texas Highway Department formed in 1917, its engineers recognized the value of university-based facilities like those at the then-Agricultural and Mechanical College of Texas (later Texas A&M University) for conducting transportation research. Fast forward to 1950 and the birth of the Texas A&M Transportation Institute (TTI) and its charter to apply Texas A&M’s […]
U.S. Roads Meant to Last Decades – But Not Forever
By: Gregory Winfree and Zachary Grasley The subject of our nation’s infrastructure is once again prominent, both in the wake of the recent release of the American Society of Civil Engineers quadrennial report card on the state of America’s infrastructure and among our policymakers in Washington, D.C. The ASCE report card presents one of those […]
Episode 9. Half the Wheels and Eight Times the Danger: Roadways are safer these days, unless you ride a motorcycle.
Passenger vehicle fatalities in the United States have declined recently, but not motorcyclist deaths, which total about 5,000 each year. Some reasons for that are obvious, as Senior Research Scientist Mike Manser notes, but the bigger picture is more complex. Advocates continue to prioritize robust safety programs targeting not only motorcyclists, but also those who […]
