Planning Makes Perfect — Addressing Construction Issues Before the Project Begins
A common sight on Texas roadways is noise walls and retaining walls. Noise walls, or barriers, are helpful in keeping the sound of a busy highway out of neighborhoods and business districts. Retaining walls reduce the need for a sloped area at grade changes and are used extensively for highway overpasses. Noise walls and retaining […]
Overcoming Barriers: Motorcycle Roadside Safety
Although motorcyclists make up only 3 percent of all registered vehicles, motorcyclists accounted for 14 percent of all traffic fatalities in 2020 in the United States. As these numbers have risen over the years, several state departments of transportation (DOTs) are taking matters into their own hands to address these related issues. In partnership with […]
Ribbon Cutting Marks Completion of I-35 Waco Project
The I-35 Waco Project is officially complete with a ribbon-cutting ceremony held Nov. 9. The $341 million project finished on budget and ahead of schedule, beating its originally estimated end date by approximately 18 months. The I-35 Waco Project is part of the larger My35 Waco District Construction Plan, begun in 2012, comprised of 17 […]

Expanding TTI’s Research Reach
Texas A&M Transportation Institute’s (TTI’s) urban research and implementation offices foster local agency cooperation and help assure implementable research results. Beyond its headquarters in Bryan/College Station, TTI supports eight urban offices across Texas; one urban office in Washington, D.C.; and two international offices in Doha, Qatar, and Mexico City, Mexico. Headquarters Bryan/College Station Urban Offices […]
Clear the Way! Emergency Vehicles En Route
During an emergency, seconds matter. However, navigating through busy urban arterials may sometimes be a tricky task for emergency response vehicles, particularly through busy intersections. In 2021, of the 633,499 roadway crashes in Texas, nearly 37 percent occurred at intersections, emphasizing the importance of improving safety in these scenarios. An ongoing research project conducted by […]
Just How Effective Are Peak-Hour Lanes?
The Dallas–Fort Worth–Arlington metropolitan area is one of the most populous metropolitan areas in the United States. With a population of over 7.5 million people — and growing — the area has rapidly become a desirable place for families and businesses to locate to over the last decade. Alongside the population and economic growth, traffic […]
TTI Provides Technical Assistance Study on Railway Grade Crossings in Mexico
Mexico’s national railway network consists of 16,700 miles of railway lines. Following a restructuring and privatization completed in 1998, the system is operated under long-term concessions to the federal government. The restructuring has resulted in the steady growth of freight rail traffic and increased efficiency. The road and rail systems intersect at more than 7,000 […]
Do Not Enter! You’re Driving the Wrong Way
Few scenarios are more terrifying for a motorist than encountering someone driving the wrong way on a freeway. When a crash occurs because of wrong-way driving (WWD), the results are often catastrophic. Such was the case on March 15, 2011, when San Antonio Police Department (SAPD) Officer Stephanie Brown was killed by an intoxicated WWD […]
AI in the Sky: Satellites, Imaging, New Technology Applications in Transportation
If you watch police procedurals on television, you’ve probably seen an episode where traffic cameras play a pivotal role in solving the crime. Usually, an analyst zooms in to identify the perpetrator’s license plate, providing the clue needed to close the case. Using the big-picture power of video imaging can be just as helpful in […]
Visualizing (and Simplifying) the Future of Transportation Planning
For many years, the Texas A&M Transportation Institute (TTI) has provided travel demand model (TDM) technique support for the Texas Department of Transportation (TxDOT) as the base of the urban transportation planning process. The TDM is critical to the transportation planning process since it is used to predict future demand for transportation facilities and services. […]
Communication Is Key — TTI Mobility Coordinator Eases the Burden of Construction in Waco
Since 2012, the Texas Department of Transportation (TxDOT) has conducted the My35 Construction Project along I-35 in Central Texas. Called “Main Street Texas” for the vital role the corridor plays in international commerce, I-35 is host to hundreds of thousands of cars and trucks each day. Comprising 17 separate construction projects, the 96-mile stretch between […]
Visualizing Disruptions on Our Roadways
Roadway congestion continues to be a frustration for drivers across the nation. Delays and slowdowns caused by crashes, extreme weather or even road debris dramatically affect the reliability of the transportation system and can add grueling hours to commuter drive times. While congestion may seem unavoidable at times, the ability to track roadway incidents and […]
