Tailoring and transportation share at least one thing in common — the better the planning, the better the product. When tailors measure cloth twice before cutting, they’re maximizing efficiency and minimizing waste by first calculating carefully. In the transportation planning arena, that’s what sustainability is all about. “Sustainable transportation” means different things to different people. [...]
Transportation, like many things in life, is easily taken for granted. As part of its bid to stimulate the national economy, the Obama Administration is focusing on improving our national transportation infrastructure. This discussion, while new to some, is actually part of a lengthier dialogue as old as the United States itself. Though there was, [...]
What impacts do tolling, transit, technology and telecommuting/travel demand management have on reducing traffic congestion in major travel corridors? Researchers at the Texas Transportation Institute (TTI) are part of a team helping the U.S. Department of Transportation (U.S. DOT) answer that question. The U.S. DOT is funding congestion reduction strategies at multiple sites throughout the [...]

What began in Europe is now the hottest thing in asphalt in Texas and the U.S. There are many ways to get there, but the goal is the same: to lower the temperature of asphalt by 35 to 100 degrees Fahrenheit prior to application. “When we started the warm mix research project, I thought we’d [...]
It’s easy enough to fix a pothole, but how easy is it to actually prevent them from appearing at all? Given the number of cracks and potholes that plague Texas roadways, there is no question about the value that a successful preventive maintenance could have in delaying more serious problems. Various methods exist to identify [...]
As the winter months wind down, Texas Department of Transportation (TxDOT) district offices throughout the state will complete planning for the hectic summer seal-coat season. Best applied when the weather is warm, seal coats are by far the most popular preventative maintenance treatment used in Texas. A recently completed research project, sponsored by TxDOT and [...]
State departments of transportation (DOTs) throughout the country are battling the same worsening problems: a lack of funds for road construction and soaring prices for materials like steel and concrete. When funds are available, these rising costs have DOTs scrambling for dollar-stretching ideas. “Construction costs have almost doubled between 1998 and 2006,” says Ivan Damnjanovic [...]
Potholes in the road cause more problems than commuters just spilling their coffee. Potholes are also a safety hazard and an expensive burden to the taxpayers footing the bill for repairs. Thermal segregation, one major cause of potholes, occurs in isolated, low-density areas when the temperature differs greatly during placement of the new overlay. Hot-mix [...]
