New York City’s roads and bridges already incur millions in annual damage from oversized trucks, and a new study warns the shift to electric freight could intensify that burden. As electric trucks replace diesel models, their heavier batteries could increase the city’s yearly repair costs by up to nearly 12% by 2050.

Led by C2SMART researchers at NYU Tandon School of Engineering in collaboration with Rochester Institute of Technology (RIT) and published in Transport Policy, the study finds that oversized trucks already cause about $4.16 million in damage each year while permits bring in only $1.28 million. Electric trucks typically weigh 2,000 to 3,000 pounds more than diesel models, and in rare long-range cases as much as 8,000 to 9,000, so the financial gap is expected to grow.

“As become more common, our city’s infrastructure will face new and changing demands to support this transition,” said Professor Kaan Ozbay, the paper’s senior author and director of NYU Tandon’s C2SMART transportation research center. “Our framework shows that the city should adapt its planning and fee structures to ensure it can accommodate the costs of keeping bridges and roads safe as a result of more widespread adoption of e-trucks. “

Using New York City’s Overdimensional Vehicle Permits dataset, the researchers modeled how electric-truck adoption could play out through 2050. They found that switching to e-trucks could increase damage costs by 2.23 to 4.45% by 2030, and by 9.19 to 11.71% by 2050. More extreme scenarios tied to unusually heavy batteries produced higher figures, though the authors say those outcomes are unlikely as technology improves.

The impact would not be uniform across the city. Manhattan faces the greatest increase, with parts of Brooklyn, Queens, and the Bronx also at risk due to heavy truck volumes and aging structures. Staten Island and many outer areas show lower impact. Bridges shoulder about 65% of the added costs because they are especially sensitive to increases in gross vehicle weight. Pavement, affected more by axle loads, wears down more gradually.

“We found that conventional oversized trucks in New York City already impose more than $4 million in annual damage,” said the study’s lead author Zerun Liu, NYU Tandon Ph.D. candidate in the Civil and Urban Engineering department’s recently established Urban Systems Ph.D. program, who is advised by Professor Ozbay. “With projected adoption of , those costs could increase by an additional nearly 12%. That gap highlights the urgent need for new strategies to keep infrastructure sustainable.”

To manage the risks, the researchers created a susceptibility index identifying road segments and bridges most vulnerable to heavier vehicles. They recommend replacing flat permit fees with flexible, weight-based fees that reflect actual costs while still recognizing environmental benefits. They also call for expanding weight monitoring on high-risk corridors, especially in Manhattan, and factoring e-truck projections into city maintenance and capital plans to avoid expensive emergency repairs.

Although the study focuses on New York City, similar pressures are emerging elsewhere. The European Union allows zero-emission trucks to exceed weight limits by nearly 9,000 pounds, while U.S. rules permit an additional 2,000. The framework developed by the NYU Tandon and RIT team offers cities a way to balance climate goals with the realities of infrastructure wear.

Despite the added costs, the authors stress that the overall case for electric trucks in New York remains strong. Their scenarios suggest that widespread electrification could cut about 2,032 tons of carbon dioxide each year, improving air quality and public health.

“The proposed methodological framework can provide actionable insights for policymakers to ensure infrastructure longevity and safety as e-truck adoption grows,” Ozbay said.

In addition to senior author Ozbay and lead author Liu, the paper’s other authors are Jingqin Gao, C2SMART’s Assistant Director of Research; Tu Lan, a Ph.D. student in the Urban Systems Ph.D. program graduated under Professor Ozbay’s advisement; and Zilin Bian, a recent NYU Tandon Ph.D. graduate from the Civil and Urban Engineering department , now an assistant professor at RIT.

What’s the Best Mattress for Sex? Our Reviewers Lay It Out for You


People take a lot of pride in their bedroom abilities. Saatva takes great pride in crafting luxurious, handmade mattresses. To maintain the good work in both situations, the Saatva Classic features an innerspring construction very conducive to lovemaking. There are actually two coil types at play here: pocketed coils beneath the pillow top, and firmer traditional coils at the base. Pocketed coils are better at responding to the situation above them, as they can provide individualized support that homes in on high-weight areas. Whether that’s your lower back while you’re sleeping, or your hands and knees when you’re more active, pocketed coils are adaptable. Traditional coils are interwoven, so they compress together. While the overall support isn’t as targeted, it still has its merits in terms of durability, edge support, full-body pushback, and airflow, particularly when things get hot and heavy. Together, they create a surface that’s easy to move around on and gives you some bounce to work with, which you’ll appreciate more in the moment as opposed to sinking too much. Use that bounce to your advantage.

Buyers can choose from Plush Soft, Luxury Firm, or Firm. I’d recommend you stick to the firmer options to avoid overt sinking, which can be a buzzkill. You can also select your ideal mattress height, with options of either 11.5 inches or 14.5 inches. The variance in firmness and height also opens up this mattress for all kinds of couples to enjoy, not just for sex but for sleeping as well. Couples with different body types and sleeping positions can find an option that works for both, such as Luxury Firm, which would suit both side sleepers and stomach sleepers. Every Saatva Classic comes with an extra lumbar support layer and quilting, regardless of height or firmness. For added coziness, the Classic features an organic cotton pillow top that gently hugs the body.

The Saatva Classic ranges from $1,399 for a twin mattress to $3,078 for a split California king.

Mattress type Innerspring hybrid
Firmness Plush Soft, Luxury Firm, Firm
Height 11.5 or 14.5 inches
Trial period 365 nights

The Pepsi Man Is Coming to Save Samsung From Boring Design

The Pepsi Man Is Coming to Save Samsung From Boring Design


Samsung has one of the biggest product line ups of any tech brand, yet when it comes to design, it’s consistently seen as an “also-ran.” While other companies have forged distinctive and instantly recognizable design languages, such as Nothing, Samsung has found itself behind in the style stakes. When you’ve got Apple as one of your biggest competitors, that’s not a great position to be in.

That’s not to say there haven’t been improvements in the last decade, and the occasional flashes of promise—most notable in its collaborations with external designers, like the Bouroullec brothers, who fashioned the Serif TV for the South Korean company. But that hasn’t stopped complaints of boring and unoriginal design, both internally and externally, and an inertia when it has led, leaving other companies to close the gap.

Being defined by performance over personality has hardly done Samsung’s bottom line any harm—it recently regained its lead from Apple in global smartphone market share and has been the global leader in TVs for almost two decades. But, in 2025, it looks there’s finally a clear desire from Samsung to bridge the gap between form and function, by giving design the focus it’s been lacking for far too long at the company.

Back in April, Samsung hired Mauro Porcini, its first ever chief design officer. Porcini has spent more than 20 years building award-winning design teams at 3M and PepsiCo, most recently leading a successful global rebrand for Pepsi—the company’s first in 14 years.

For a company as big as Samsung, this hire feels late. Apple created the same position for Jony Ive a decade ago, around the same time it was reported that innovation at Samsung was being stifled beneath layers of management. With those structural issues supposedly unpicked, Samsung now has work to do—something Porcini is keen to acknowledge.

Late to the Party

“We are in a moment of change, where the way people interact with any kind of machine or electronic device is going to be radically different in the coming years,” Porcini tells me. “These machines will change the way people live, work, and connect with each other—the way people fulfil their needs. For a company like Samsung, having design at the top, involved in the way you define the future of the portfolio based on those needs—it’s more important than ever.”

The march of AI is, of course, a helpful hook upon which to tie this long overdue move, but Yves Béhar, the founder and principal designer at Fuseproject who worked with Samsung on The Frame TV, tells me this has been years in the making, and something Samsung had initially looked externally to help put the wheels in motion.

“When we started working with Samsung on The Frame [released in January 2017], the CEO at the time, HS Kim, came to us and said—look, we want to transform ourselves from a consumer technology company, into an experience business,” says Béhar. “So we helped them set some principles around that, and worked on getting that message out into the business—of what it means to think about experience versus tech. This is exactly what we did with The Frame TV.”

Pedestrian deaths at midblock bus stops found to be up to 5 times higher

Pedestrian deaths at midblock bus stops found to be up to 5 times higher

Bus transportation is an essential part of nearly every public transit system. From school students to everyday workers, riders depend on buses to transport them to the essential destinations. Because most passengers start or end their journey by walking, providing safe access to bus stops is key to enhancing pedestrian safety.

Pedestrian fatalities in the United States have significantly increased in recent years, with 2022 recording the most fatalities since 1981. While prior studies have analyzed bus stop using data, not all crashes near were directly related to the stop itself.

Candace Brakewood, an associate professor in the Department of Civil and Environmental Engineering, worked with Graduate Research Assistant Allison Rewalt and fellow CEE Professor Chris Cherry to address this gap by analyzing fatal transit bus stop-related pedestrian crashes from the Fatality Analysis Reporting System (FARS) and comparing them to other nearby fatal pedestrian crashes.

Their research, titled “An analysis of pedestrian safety at bus stops using FARS data,” was recently published in the Journal of Safety Research.

The research was funded through the Center for Pedestrian and Bicycle Safety(CPBS), which is a Tier I University Transportation Center (UTC) that is led by the University of New Mexico and includes UT, and a Dwight D. Eisenhower Graduate Fellowship that Rewalt received.

“Our work is unique because most prior studies used a more localized approach, relying on local or state crash data to understand the risks pedestrians face when walking to or from bus stops, whereas ours uses a national dataset to give us a bigger picture of what these risks look like nationwide,” Rewalt said. “Because our work is generalizable, it can be used to inform bus stop safety improvements across the country.”

Midblock stops present danger

The study uses pedestrian crash data that explicitly identifies bus stop-related crashes, providing a more nuanced assessment of crash risk factors for transit passengers and other pedestrians in the area, compared to previous studies that relied simply on proximity or other measures.

One of the key takeaways from the research is that there are three typical types of crashes that result in pedestrian fatalities at bus stops:

  • pedestrians crossing to/from a bus stop at an intersection
  • pedestrians waiting on the roadside at a midblock stop
  • pedestrians crossing to/from a midblock stop.

Midblock stops are especially high risk, especially on high-speed arterials. Midblock locations increased the chances of a fatal crash by 4.7 to 5.2 times depending on the size of the buffer zone used in the analysis.

Pedestrians waiting on the roadside at a midblock stop is a crash subtype that is distinct to transit passengers, who often wait at the roadside for the bus to come, whereas other pedestrians would typically not be standing on the roadside for an extended period of time.

“This finding stood out because it points to a practical place to focus safety improvement near bus stops,” Rewalt said.

Finding infrastructure solutions

The UT researchers are hoping , traffic engineers, and transit agencies can use their research findings to explore solutions to mitigate risk for pedestrians accessing buses. High-visibility crosswalks, especially at midblock crossings, or relocating bus stops closer to a signalized intersection could be infrastructure improvements to consider.

“We have an ongoing follow-up research project that continues to explore at bus stops using a different nationwide dataset called CRSS that includes non-fatal crashes,” Brakewood said. “The overarching goal is to identify bus stop-related crash characteristics and determine which factors lead to more severe outcomes. We will have more results to share on the new project in the near future.”
