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 […]

The Last Stop with Greg Winfree: Mobility, Up Close and Personal
It was Tip O’Neill, a former speaker of the U.S. House of Representatives, who was famously known to say in the 1980s, “All politics is local.” Countless candidates for office decades later routinely rely upon door knocking and town hall gatherings, attesting to both the durability and relevance of O’Neill’s philosophy. His words concisely captured […]
Episode 40. Of Needles and Haystacks: For truck drivers, finding a parking space is tougher than ever.
The COVID-19 pandemic helped to expose a chronic shortage of truck drivers in America – and a scarcity of places for those truckers to park, too. That has big implications for how we get the products we need, and how much we pay for them.

Episode 39. All over the Map: Just two car guys talking about transportation.
From self-driving tech to safety culture and power grids. When a transportation research leader and an auto industry journalist cross paths, the conversation can go in many directions.
How a More Forgiving Roadside Could Impact Severity of Crashes
Side roads, main roads, and highways have seemingly transformed into race tracks or obstacle courses during the last couple of years. Drivers slowing down, wearing seatbelts and not being under the influence can help reduce the number of deaths on roads; however, Texas A&M Transportation Institute (TTI) researchers are also working on other ways to […]
Episode 38. Safety in Numbers? As bicycle use grows more popular, crash numbers carry mixed messages.
Along with the growing popularity of bicycling comes an increased need for safety. But while the number of bicycle crash injuries dropped during 2020, that was not the case for bicycle crash fatalities. TTI researchers Bahar Dadashova and Joan Hudson take a close look at that pattern, and what can be done about it.
Texas Needs to Consider New Ways to Fund Its Highways
By Brianne Glover Relying on gas tax is outdated as travel, vehicles become more diversified. Amid all the news of record-breaking inflation, it’s hard to think of anything that doesn’t cost more than it did a year ago — much less 30 years ago. To find one example, though, just think of your vehicle’s fuel. […]
