TTI, TxDOT Win National Safety Award: “Safer by Design” Tool Aims to Save Lives on Texas Rural Roadways

December 1, 2021

The Roadway Safety Foundation honored the Texas A&M Transportation Institute (TTI) and the Texas Department of Transportation (TxDOT) with a 2021 National Roadway Safety Award Oct. 6. The foundation lauded the TxDOT-sponsored, TTI-developed “Safer by Design” tool for use by roadway designers to assess the safety characteristics of rural highway design. Nearly 4,000 people died […]

TTI Becoming Known for Expertise in Retrofitting Bridges

December 1, 2014

Transportation research often focuses on finding safer and more efficient ways of doing things. A case in point is older bridges. Some features may need to be modernized to make older bridges safer and more reliable. “The nation’s infrastructure is wearing out,” says William Williams, an associate research engineer at the Texas A&M Transportation Institute […]

Helping TxDOT Build Better Bridges

September 1, 2014

BRIDGE TO THE PAST One often hears the phrase, “They just don’t build ’em like they used to.” It’s true of many things, including bridges. In Fort Worth, Texas, local historic preservation groups expressed concerns that historically significant bridge structures in the area could be endangered due to infrastructure upgrades demanded by modern traffic. In […]

Designing and Maintaining Tougher Roadways for Texas

September 1, 2014

Oil and gas production has increased dramatically in Texas in recent years, and every indication is that this trend will continue into the foreseeable future. The state now has 48 percent of all active drilling rigs in the United States. Many of these rigs are in the Eagle Ford Shale play in South Texas. Recent […]

Road Design Training in Kosovo

June 1, 2011

TTI Contributes to a Unique Public-Private Partnership Good roads are vital to progress, especially in newly established and developing countries. After more than a decade of war and political unrest, Kosovo emerged as the world’s newest independent state in early 2008. But the country’s roadway infrastructure was severely deteriorated and in need of reconstruction. To […]

THEN: Application of Technology In Traffic Operations Research Goes Back to Earliest TTI Studies

March 1, 2010

(excerpt from “A Study of Freeway Traffic Operation” by Charles J. Keese, Charles Pinnell and William R. McCasland, 38th Annual Meeting, Highway Research Board, Washington, D.C., January 5-9, 1959) In 1956, the Texas Transportation Institute initiated a research project for the Texas Highway Department to correlate freeway operational characteristics with design features.…The study was made […]
