Transportation

Prof. Jessika Trancik speaks with Bloomberg reporter Kyle Stock about the importance of scrappage programs, especially those that incentivize electrifying the current fleet of vehicles in the United States. “At any given point in time, you care about the composition of the fleet,” says Trancik. “Funding programs that would help turn over the fleet more rapidly makes a lot of sense.”

Writing for the Financial Times, Prof. Carlo Ratti explores the concept of the “15-minute city,” which is aimed at creating walkable neighborhoods. “The 15-minute city must be paired with investment in transport between neighborhoods,” writes Ratti, noting that investment is especially needed in public transportation to ensure that 15-minute cities do not contribute to greater segregation.

Senior Lecturer and Senior Research Associate Fred Salvucci BS '61 SM '62 speaks with GBH’s The Big Dig Podcast host Ian Coss about his role in Boston’s “Big Dig” project. “The idea for the Big Dig began with an unlikely friendship,” explains Coss. “During the highway debates in the early 70s, Fred Salvucci – one of the highway opponents – went to a ton of meetings. And across the table at many of those meetings was a man named Bill Reynolds; he was there to represent the road builders.”

Prof. Jinhua Zhao writes for Boston Magazine about how artificial intelligence could help improve the MBTA system. “When something significant happens on public transportation—the line is down, the road is congested, some bridge is blocked—the customer is suddenly stuck in the system and needs more help,” writes Zhao. “For when that happens, we developed a solution to send individualized guidance for a better transit option to that person, communicated by text message or an app.”

Nature reporter Andrew Robinson spotlights “Atlas of the Senseable City” a new book co-authored by Prof. Carlo Ratti. The book is a “highly illustrated collection of digital maps,” Robinson notes, adding that it “analyzes four essential urban dimensions: motion, connection, circulation and experience.”

Studies by researchers at MIT have found “that shifting to electric vehicles delivers a 30% to 50% reduction in greenhouse gas emissions over combustion vehicles,” reports Tom Krisher for Associated Press. According to Prof. Jessika Trancik, “electric vehicles are cleaner over their lifetimes, even after taking into account the pollution caused by the mining of metals for batteries,” writes Krisher.

Prof. Yossi Sheffi speaks with Marketplace host Meghan McCarty Carino about how AI has impacted the workplace, highlighting the wide deployment of robots in warehouses. “Instead of people running around the warehouses, the people stand and the robots run around the warehouses,” Sheffi said. “But they bring the work to the people who then put it in boxes, package them.”

Researchers from MIT have found that since the Covid-19 pandemic, there has been a decrease in the number of interactions between people from different socioeconomic backgrounds, reports Danny Westneat for The Seattle Times. “It’s creating an urban fabric that is actually more brittle, in the sense that we are less exposed to other people,” says research scientist Esteban Moro. “We don’t get to know other people in the city … to know other people’s needs. If we don’t see them around the city, that will be impossible.”

Lecturer Jim Aloisi speaks with CNN reporter Nathaniel Meyersohn about how Taylor Swift’s sold-out Eras Tour is impacting public transportation across the United States. “What Taylor Swift is doing, and I thank her for this — although I don’t know she intended to — is proving that if you give people better, reliable transit alternatives, they’ll take it,” says Aloisi. “They would prefer to do that than be stuck in soul-crushing traffic.”

MIT researchers have developed a new compact, lightweight design for a 1-megawatt electrical motor that “could open the door to electrifying much larger aircraft,” reports Ed Gent for IEEE Spectrum. “The majority of CO₂ is produced by twin and single-aisle aircraft which require large amounts of power and onboard energy, thus megawatt-class electrical machines are needed to power commercial airliners,” says Prof. Zoltán Spakovszky. “Realizing such machines at 1 MW is a key stepping stone to larger machines and power levels.”

Alumni Billy Thalheimer and Michael Klinker co-founded Regent, a company that has developed and manufactured an all-electric sea glider, reports WCVB. “A sea glider is a class of vehicle known as a wing in ground (WIG),” says Thalheimer. “So, it flies within a wingspan of the surface at all times, dock to doc, exclusively over water.”

Prof. Jessika Trancik speaks with Popular Science reporter Charlotte Hu about the impact of electric vehicles on the environment. “There’s definitely a number of different modes of transport that need to be addressed and green modes of transport that need to be supported,” says Trancik. “We really need to be thinking holistically about all these ways to reduce greenhouse gas emissions.”

Researchers from MIT have found that, as a result of the Covid-19 pandemic, people are less likely to explore economically different parts of their home cities, reports Immanual John Milton for Bloomberg. “Fewer people are visiting attractions like museums, restaurants or parks that are outside their immediate mobility radius, and they’re spending less time among residents at different socioeconomic levels,” writes Milton.

MIT researchers have found that interactions between people from different economic backgrounds have dropped significantly since the start of the Covid-19 pandemic, reports David Scharfenberg for The Boston Globe. Scharfenberg notes the “the phenomenon could hurt low-income people in direct ways – they’ll lose connections to better-off people – and indirect ways.”

Prof. Yossi Sheffi, director of the MIT Center for Transportation and Logistics, speaks with David Wade of WBZ News about AI and the future of work. "Jobs will change, clearly some jobs will disappear. I don't want to minimize it," says Sheffi. “Some jobs will disappear, but this is a very small number. Most of the impact of technology is to assist."
