MapLite, a new system developed by CSAIL, aims to help autonomous vehicles navigate uncharted areas, writes Jesus Diaz for Co.Design. “[I]f autonomous cars can reach the millions of people who live beyond the city and are unable to pilot their own vehicles,” said graduate student Teddy Ort, “they will be uniquely capable of providing mobility to those who have very few alternatives.”
MIT spinout ClearMotion’s “Proactive Ride” system accounts for bumps and potholes in the road, with quick-sensing hydraulic actuators that can adapt to imperfections to create a smooth ride. “Every car with ClearMotion also maps the surface of that road, and shares it with other equipped cars,” says Mike Wankum for WCVB. “A car approaching a rough patch already knows about it before encountering the first bump.”
In a commentary for Nature, Ashley Nunes, Bryan Reimer and Joseph Coughlin of the MIT AgeLab discuss how current legislation does not sufficiently account for the risks associated with operating autonomous vehicles. “Policymakers need to work more closely with academics and manufacturers to design appropriate regulations,” they write. “This is extremely challenging because the research cuts across many disciplines.”
MIT researchers have developed an autonomous tricycle that can transport people and packages, writes David Silverberg for Motherboard. “The innovation created by MIT is dubbed PEV (Persuasive Electric Vehicle), and sports a 250W electric motor and 10Ah battery pack. It can run on 25 miles per charge with a top speed of 20 miles per hour.”
Forbes reporter Laurie Winkless writes that MIT researchers have found that if drivers maintained fixed distances between the cars in front of and behind them they would be able to reduce traffic jams. “We humans tend to view the world in terms of what’s ahead of us, so it might seem counter-intuitive to look backwards,” explains Prof. Berthold Horn.
CNN reporter Matt McFarland writes that CSAIL researchers have proposed that outfitting cars with cruise control systems that maintain equal distances between cars could help alleviate phantom traffic jams. The researchers’ simulations showed, “keeping the same distance between the vehicle in front and the vehicle trailing a car prevents traffic jams.”
CSAIL researchers have found that if drivers could maintain an equal distance between cars they would be able to reduce the number of traffic jams, reports Matt Burgess for Wired. The researchers found that, “by adding sensors to the back of cars that take into account the speed of following vehicles, it will be possible to better regulate traffic.”
Research engineer Bryan Reimer speaks with Ashley Halsey of The Washington Post about the need for a national conversation to determine how safe driverless cars should be before they become more widely available. “Unless we have defined how safe is safe enough — and we are in agreement — the nature of politics is that fingers will point at each other,” says Reimer.
MIT spinoff Optimus Ride will be bringing autonomous vehicles to a new development in South Weymouth, reports Adam Vaccaro for The Boston Globe. The company is currently running tests in the streets, “but it expects to haul passengers around the development site as part of a pilot program at some point in 2018,” writes Vaccaro.
In a letter to The Financial Times, Prof. Jessika Trancik, postdoc Geoffrey Supran, and graduate student Marco Miotti clarify results from a study the lab released last year that compares emissions of gas and electric vehicles. “Not only do electric cars usually emit less than petrol ones already, but over time, as the carbon footprint of electricity continues to fall, that gap will widen,” the researchers explain.
Research engineer Bryan Reimer speaks with Chuck Tannert of Fast Company about the need for more investment in technology that can help make cars safer. “It is clear that safety on the nation’s roads is in question, necessitating a review of investments to double down on what is working and innovate where needed,” Reimer explains.
Research Engineer Bryan Reimer speaks with Anthony Brooks of WBUR’s Radio Boston about the possibility of creating more car-free zones in Boston. Creating a car-free zone is possible, says Reimer, but “it’s going to take a long-term focus and shifting the vehicular traffic around.”
Prof. Eran Ben-Joseph visited the intersection where the BU Bridge meets Commonwealth Avenue in Boston with Gabrielle Emanuel of WGBH to discuss how to improve the area. In order to make the intersection safer for pedestrians and cyclists, Ben-Joseph recommended taking space away from cars, changing the intersection’s surface and adding design elements to make the space feel more urban.
Prof. Ben Olken speaks with BBC News reporter Gareth Mitchell about how the cancellation of high-occupancy vehicle (HOV) lanes impacted traffic in Jakarta, Indonesia. Olken and his colleagues found that in addition to traffic substantially increasing in areas that previously had HOV lanes, without the carpool lanes, “traffic gets worse all over the city.”
A study by MIT researchers shows that carpool lanes can help reduce a city’s traffic, reports Matt McFarland for CNN. The researchers found that the removal of HOV lanes increased driving times across Jakarta, Indonesia. "The magnitude was enormous and more than I would've expected," says Prof. Ben Olken.
