The world is changing. Used to be, national borders had one purpose: to act as a line a nation didn’t dare cross unless that nation wanted a war. Today — with the Internet cross-pollinating cultures between countries at the speed of light and a global economy dependent on streamlined international trade — national borders are [...]
TTI Celebrates 50 Years with NCHRP by Dennis Christiansen Agency Director In 2012, we celebrated the 50th anniversary of the National Cooperative Highway Research Program (NCHRP). As I’m sure you know, NCHRP sponsors research in a wide range of topics critical to state departments of transportation. Doing so saves time, effort and resources in solving [...]
Better, Stronger, Together: TTI and the Texas Department of Transportation by Dennis Christiansen Agency Director Shortly after it was formed in 1917, the Texas Highway Department came to the Agricultural and Mechanical College of Texas looking for answers. Can we make this road last longer? Can we save taxpayer dollars and still do a better [...]

Vehicles are more protective than ever before. The roadway environment is far more forgiving. Traffic laws have evolved and become more effective over time. By almost any measure, roadway safety has advanced remarkably in a relatively short time, but engineering and enforcement will take us only part of the way. To move forward, meaningful safety [...]
What It Takes Is Dollars and Sense Getting where you’re going costs money. Whether that’s bus fare, filling up your gas tank or keeping our transportation system operational, it all costs money. And it’s getting more expensive. How much we pay at the pump might be the most visible reminder that transportation isn’t free, but [...]
Or, Why Transportation Research Is More Important Than Ever It’s hard to tighten your belt when you run out of holes in the leather. But when you can’t afford a new belt, you just have to work with what you’ve got. In a nutshell, that’s what the Texas Legislature is facing in the current budget [...]
