Transportation

In an opinion piece for the Boston Globe, Research Scientist Jim Aliosi advocates for reliable public bus service along Blue Hill Avenue in Boston’s Mattapan neighborhood. “Each day more than 30,000 riders use one of the bus routes using Blue Hill Avenue, and each day they collectively lose 3,000 hours of precious time due to traffic congestion and impediments like double parking,” writes Aliosi, “Bus rapid transit will change all that in this decade.”  

Prof. Alessandro Acquisti speaks with NPR’s Scott Neuman about privacy issues related to surveillance by autonomous vehicle (AV) companies. “There already exist laws that govern duty to report or even duty to protect [for AV companies],” Acquisti says. “The privacy problems arise when and if driverless carrier companies used such laws or ethical obligations as a pretext for blanket, indiscriminate accumulation of identifiable data for unspecified future purposes.” 

Prof. Jinhua Zhao takes a car ride through Boston with GBH “Curiosity Desk” host Edgar B. Herwick II to discuss the concerns and benefits of self-driving technology entering the city. “We pay a lot of attention to how good AV [Autonomous Vehicle] safety needs to be, but it’s important for us to understand how bad we have been—the current system is [bad],” says Zhao. “When human drivers are aggressive, they actually indeed pose a challenge on AV—which is that AV needs to learn how to be assertive. If you’re too conservative, you’ll just be stuck there going nowhere.”

In a New York Times opinion piece, Prof. Carlo Ratti examines the debate around Ferrari’s first electric vehicle (EV) and the future of EV self-driving technology. “The self-driving technology available in most EVs turns the car into something summoned on demand,” writes Ratti. “Our work at the Massachusetts Institute of Technology suggests that autonomous driving could allow cities to operate with a small fraction of today’s vehicles while reducing parking demand by as much as 85 percent.”

For Axios Boston, reporter Steph Solis highlights “Anita,” a solar-electric boat created by alumnus James Worden ‘89 that is due to launch this year. The boat was previewed at the 80th anniversary Charles River sail-a-thon. “The prototype, named ‘Anita’ after Worden's late wife, moves silently with no fumes or exhaust and uses LiFePO4 battery cells with a battery management system (it lets you charge the batteries while they're in use),” writes Solis. 

NPR reporter Jeff Brady spotlights a study by Prof. Jessika Trancik and Marco Miotti PhD ’20  that found “across most of the U.S., electric vehicles are cost-competitive with their gas counterparts. And it found that in most locations, EVs also reduce emissions between 40% and 60%.” 

MIT researchers have developed a new traffic navigation system that more accurately reflects travel time by including parking data, reports Catherine Parotta for Boston 25. “What we can do is figure out if you’re best off trying this parking lot first, even if it’s farther than the closest parking lot,” explains Prof. Cathy Wu. Graduate student Cameron Hickert adds that: “We hope that this can help people make better decisions." 

Lecturer Jim Aloisi speaks with Boston Globe reporter Ian Prasad Philbrick about fare evasion on the MBTA, and a need for transit reform. “The drill here shouldn’t be to obsess or focus about how much,” says Aloisi. “The drill should be where can we make cost-effective interventions that matter?”

David Zipper, a senior fellow at the MIT Mobility Initiative, writes for Fast Company about the risks associated with introducing driverless vehicles to European cities. “Technological marvels they may be, but robotaxis are still cars and cars are a uniquely inefficient means of moving large numbers of people when space is at a premium,” writes Zipper. “By inviting robotaxis into their narrow, busy streets, European cities risk worsening congestion.” 

Christina Cassotis MBA '14 speaks with Business Insider reporter Kelsey Vlamis about her experience and goals for the airline industry as CEO of Pittsburgh’s airport. “I love my job, and I like thinking about my job,” says Cassotis. “Of course, it's stressful, but it's the kind of stress I'm built for. I am very good at managing lots of complexity. I really love understanding stakeholders and what they need and how to communicate with them. We're constantly looking for better ways to do things. I care a lot about making sure our staff feels engaged. Airports are fun places to work.” 

Prof. Carlo Ratti speaks with Reuters reporter Catherine Early about the growing number of initiatives aimed at creating more walkable neighborhoods in urban cities. “Small, tangible changes – like pedestrianizing a block, repainting a square, or hosting a street festival – help people understand what proximity feels like in practice,” Ratti explains. “When people are involved in shaping their environment, skepticism often turns into ownership.” 

Business Insider reporter Julia Hornstein spotlights Sampriti Bhattacharyya PhD '17, CEO and co-founder of Navier, a startup working to build hydrofoil boats. “Bhattacharyya says the hydrofoiling technique consumes 90% less energy than its traditional gas counterpart and creates a stable glide even in the choppiest of conditions, eliminating seasickness,” writes Hornstein.

Writing for Meteorological Technology International, Alex Pack explores how MIT researchers have developed a new “lightning-prediction model that could help protect more unconventional aircraft designs – such as blended-wing bodies or truss-braced configurations – as aviation moves beyond traditional tube-and-wing designs.” 

Writing for Bloomberg, Prof. Carlo Ratti explores how street configuration and design can help reduce traffic speeds. “In studies we have conducted at our Senseable City Lab, we found that the posted speed limits often have little effect on how fast people drive,” writes Ratti. “Instead, the policies that work involve the design of the street itself.” 

Prof. John Hansman speaks with Newsweek reporter Anna Skinner about the logistics behind flying an aircraft through a hurricane. “Flying through a hurricane at altitude is not particularly hazardous, particularly if you are above the tops of the clouds and the turbulent layer,” explains Hansman. “It is more hazardous to land or take off in those conditions where there are high winds and rain."
