For the last four decades, TTI and TxDOT have ensured that wet-weather travel on the state’s 80,000 miles of roadways is safe — thanks to evaluating highly sophisticated and seldom-seen pieces of machinery.
AUSTIN — Texas highways are safer now thanks to hundreds of projects completed in the last few years to add shoulders, width on more than 1,000 miles of rural, two-lane highways. An analysis of 189 Texas Department of Transportation (TxDOT) road projects around the state shows that wider pavements make highways safer and result in […]
As the paint–glass bead mixture used in roadway markings for light retroreflection is applied to the road, degrades over time, and is reapplied, what effect does it have on the people handling it and on our environment?
Picture a system in which transporters powered by electric motors carry trailers from trucks and containers from ships on an elevated track above existing highway right-of-way, safely separated from passenger traffic.
In recent years, there has been a boom of energy-related activities in Texas, but many short- and long-term impacts on the state’s right-of-way and infrastructure are not properly documented.
Two recent research studies on pedestrian crossings have aimed at making crosswalks safer and more efficient. Both studies are influencing national standards and making conditions better for pedestrians.
Alcohol related statistics are staggering and have led Maury Dennis, with the Center for Alcohol and Drug Education Studies, to dedicate his career to educating the public about problems caused by alcohol and drug abuse.
Motorcycle fatalities in Texas declined in 2009, halting an 11-year trend of steady increases, but there is no complacency among state officials. The Texas Department of Transportation (TxDOT) Traffic Safety Program funded several projects to keep the momentum going and continue statewide efforts to improve motorcycle safety. Center for Transportation Safety (CTS) Research Scientist Patricia […]
Since opening in 2001, Center for Transportation Safety staff have impacted traffic safety in Texas with research, public outreach and data analysis.
To lessen the number and severity of train incidents, the Texas Transportation Institute’s (TTI’s) Rail Research Program is developing course materials for the Long Island Rail Road.
If you want safer roads, you have to have accurate and effective crash reporting.
Public policy and public opinion don’t necessarily go hand in hand, but when it comes to red-light cameras, two new studies suggest they do. According to the Insurance Institute for Highway Safety (IIHS), most drivers like the cameras. And according to the Texas Transportation Institute (TTI), they work. The TTI study, although limited to Texas, […]
Texas’ Click It or Ticket (CIOT) campaign achieved a significant milestone this year — 10 years of success. Since the campaign began, safety-belt use in Texas has reached record levels.
The Federal Highway Administration (FHWA) publishes the Manual on Uniform Traffic Control Devices (MUTCD) establishing national standards for all traffic signs. All agencies that maintain public roadways use the MUTCD to ensure signs and markings are uniform in their design and placement. Until recently, the MUTCD did not address when a traffic sign should be […]
Consistency is an important principle in roadway safety. It ensures that roadways conform to recommended guidelines and promote safety to drivers. The Texas Transportation Institute (TTI) has developed the Radiusmeter to help improve consistency on horizontal curves. “A large percentage of crashes occur on horizontal curves on two-lane highways,” says Paul Carlson, head of TTI‘s […]
It’s five times safer to travel on our nation’s roadways today than it was five decades ago. For every 100 million miles Americans traveled in 1960, five people died. Today, the rate has dropped to just over one death per 100 million miles. “As a nation 50 years ago, we decided that killing tens of […]
In Field of Dreams people from all over the country came to a baseball field to relive their childhood fantasies of playing alongside their favorite players. The playing field in the movie was magical…but how about polluted? Pollution is certainly a problem in the real world, and especially in our nation’s waterways. Everything from household […]
Drivers have numerous tools they can use in their quest to drive safely. Properly maintained traffic signs and pavement markings are two of them. The Federal Highway Administration (FHWA) originally aimed its Manual on Uniform Traffic Control Devices (MUTCD) at ensuring that signs and markings were uniform in their design and placement. This promoted consistent […]
In the Middle Ages, gate keepers had it relatively easy. Castles were considered the pinnacle of defensive warfare technology. Then gunpowder was invented, and holes blasted in stone walls caused medieval strategists to reevaluate their old way of thinking. A similar change has occurred following terrorist attacks of the last 15 years, where the preferred […]
