Transportation Troubleshooting: Coordinated and Adaptive Ramp Metering for Faster, Safer Highways
I doubt any driver likes being held back by a traffic signal while trying to enter a highway. But from a regional traffic-management perspective, there’s a lot to like about the potential to use ramp metering to improve traffic flow along congested highway corridors. What’s the CARM? With vastly more-powerful traffic sensors, computers and software than in the early years of ramp metering, transportation managers can holistically operate highway corridors and surrounding arterials to mitig...

Mode Shift: High-Speed Rail Readies for Arrival Across California’s Central Valley
Stretching back to 2008 when Californians voted to invest in electrified high-speed rail, the plan for CA HSR is to connect each of the state’s major population centers faster, safer and smarter than ever before. Along the way, from Merced to Bakersfield, California’s grapevine communities will benefit from an infusion of place-based purpose and forthcoming pride. Fundamentally, the aim of infrastructure is to make life easier; in an ideal world, equitably for all. Be it a br...
Needing Every Last Drop: Western States Are Recycling Wastewater in a Variety of Ways
A rendering shows the interior view of the membrane treatment area at the Advanced Water Purification Facility being developed in El Paso, Texas. As water scarcity continues to be a concern—particularly in the western United States and as growing populations place more demand on water-delivery systems—communities are engineering ways to mitigate the challenge through recycled water projects. Texas-Sized Water Recycling In El Paso, Texas, El Paso Water (EPWater)...
Effects of the EPA WOTUS SCOTUS Decision on Engineering
The recent U.S. Supreme Court decision limiting the Clean Water Act (CWA) jurisdiction over “adjacent wetlands” to those having a continuous surface connection to bodies that are “waters of the United States” (WOTUS) with no clear demarcation between the “waters” and wetlands has been hailed by some and criticized by others. EPA’s New WOTUS Rule to Conform with Sackett On Aug. 29, 2023, the U.S. Environmental Protection Agency (EPA) and the U.S. Army Corps of Engineers announced a final ru...
Off Rope! Drones for Bridge Inspection Increase Safety, Decrease Costs
It requires a few things for a bridge engineer to become a rope-access technician and climb up and down the most-difficult and complicated bridges: • No strong fear of heights. The photos in this article show that to be obvious. • A lot of training. Any technician needs to become certified by the Society of Professional Rope Access Technicians (SPRAT). The highest level (Level Three) requires hundreds of hours of rope work as well as completing three training programs and exams. • An in...
AI Brings a New Era of Sustainability to Structural Engineering
Construction workers put together a truss frame designed through AI. Every year brings new technological innovation to the engineering sector. For example, the industry now is in an age in which 3D-printed structural parts and generative-design artificial intelligence (AI) work together to suggest bridge concepts. The pressure to balance resource-intensive machinery and tech tools with sustainability is more critical, especially as more people and businesses are aware of t...
World Logistics Center: Engineering Heavyweights Collaborate to Ease California’s Warehouse Space Demands
Artist’s renderings show the World Logistics Center, which is set to break ground in Moreno Valley, Calif., later in 2023. (Stantec/Highland Fairview) The quest for warehouse space is more challenging than ever. Vacancy rates are at an all-time low in metropolitan areas across the United States, according to Prologis, a real estate investment trust headquartered in San Francisco that invests in logistics facilities. The situation is particularly dire in California for several reasons, incl...
Ready to Roll: How 1,000 Pounds of Spinning Metal Overcame Onramp Runoff
To complete a Missouri ditch-liner project, Realm Construction poured 400-450 linear feet of concrete a day and finished the project more than one week ahead of schedule. Near the Kansas City International Airport lies a well-traveled but problematic onramp that connects NE Cookingham Drive to I-435. A field that runs parallel to the ramp often produces significant rainwater runoff that makes its way onto the onramp. Sedimentary dirt and debris would fill the south side of th...
