In using roadsides for the collection of solar power, can we succeed in achieving both environmental and economic goals? It all depends on how you define “success.”

Traffic congestion is relative, because what constitutes gridlock depends a lot on where you live. Clearly, though, it’s no longer just a big city problem. 

As we gather for the 97th Annual Transportation Short Course, we're revisiting our interview with Texas Department of Transportation CEO Marc Williams from approximately one year ago. Despite some Texas-sized mobility challenges and worldwide supply-chain obstacles, the guy in charge of the Texas Department of Transportation wants you to know he’s never been more optimistic about our transportation future.

Thousands of long-haul truck drivers in America share a common and constant challenge of remoteness. They find insight and community through the vast reach of satellite radio. 

 It’s been said that all politics is local. Given the unique nature of major population centers everywhere, the same could be said for transportation. 

Obvious pressures when we’re driving on the roadways—like aggressive drivers, stormy weather, and unruly passengers—are widely recognized. But less conspicuous triggers can compromise safety, too. 

Decarbonizing the transportation sector—the single-biggest source of greenhouse gas emissions—won’t happen overnight. But the U.S. Department of Energy has a plan.

The dangers for those who travel on foot have constituted a public health challenge for as long as we’ve had motor vehicles. Why are pedestrian deaths increasing so fast? And what can be done to stem the tide?

Disasters – whether natural or man-made – can cripple transportation systems. Sophisticated modeling can go a long way in minimizing disruptions and restoring routine conditions. 

Two years have passed since America’s last road and bridge report card, and we’ll wait another two years for the next one. An unofficial mid-term grade suggests that conditions are improving.

Texas owes its transportation primacy in large part to an elite group of visionary leaders whose contributions merit permanent and meaningful places in the Lone Star State’s history.

In recent years, roughly half of the motorcyclists involved in fatal crashes in Texas were unlicensed. Safety advocates are working to enlist more instructors who can help riders develop the safety skills they need.

Nearly 300 million vehicles are on American roads today. Nearly all of them run on gasoline or diesel, so a large-scale shift to electric power would be transformative. A new Texas A&M University System venture is working to figure out how that might work. 

As a transportation journalist, Bernie Wagenblast has been weaving narratives of a professional sort for more than 40 years. As it turns out, one of her most recent stories is more personal.

The value that small general aviation airports deliver far exceeds what their modest size might suggest. To many local government officials, those facilities represent “the most valuable mile of pavement in the county.”

As we’re about to observe National Work Zone Awareness Week and in light of a work zone crash last month in Maryland, in which 6 workers were killed, we're revisiting a discussion with TTI's Jerry Ullman, research engineer and highway work zone safety expert. The number of fatal crashes in America is up by about 7 percent over the past decade. But in roadway work zones, it’s up by more than 40 percent. Jerry discusses why those work zones are dangerous not only for those who work in them, but...

Major railroad disasters tend to produce major news headlines, but there are hundreds of derailments each year in America that we never hear about. Why is that?

It’s been said that journalists are responsible for writing the first draft of history. As the transportation writer for the Houston Chronicle, Dug Begley has been crafting that city’s mobility story for more than a decade. 

Even after wrapping up a 46-year stretch at TTI, Tim Lomax still enjoys the adrenaline rush that comes from finding new traffic challenges, and fixing them. 

America’s roads were built to last, but they weren’t built to last forever. New research is taking a forensic approach to maintaining and repairing our surface transportation infrastructure.

Most of what we buy and use every day comes to us on cargo ships, which represent essential links in worldwide distribution systems. A global public health crisis reminded us of how important they really are.

Big-time athletic events can create big-time roadway gridlock. Experts game out the possibilities to navigate chaos – from the first car in, to the last one out. 

Wrong-way crashes on high-speed roadways are uncommon, but they’re almost always fatal. Ongoing research is supporting countermeasures to help drivers avoid – or escape -- a rare but perilous roadway hazard.

Rail industry employees and management were at odds for months and on the verge of a nationwide shutdown, until Congress and the White House invoked an arcane 1926 law to settle the dispute in only a few days. 

The Institute of Transportation Engineers is wrapping up a pivotal year in its history. Jeff Paniati, the organization’s CEO, and TTI's Beverly Kuhn, its outgoing president, talk about lessons learned from the past 12 months and how the transportation profession is evolving -- along with society.
