Machine Learning Algorithms Help Predict Traffic Headaches

Urban traffic roughly follows a periodic pattern associated with the typical "9 to 5" work schedule. However, when an accident happens, traffic patterns are disrupted. Designing accurate traffic flow models, for use during accidents, is a major challenge for traffic engineers, who must adapt to unforeseen traffic scenarios in real time.

A solar cell that does double duty for renewable energy

In the quest for abundant, renewable alternatives to fossil fuels, scientists have sought to harvest the sun's energy through "water splitting," an artificial photosynthesis technique that uses sunlight to generate hydrogen fuel from water. But water-splitting devices have yet to live up to their potential because there still isn't a design for materials with the right mix of optical, electronic, and chemical properties needed for them to work efficiently.

Uber urges drivers to go electric

Studies have found that when shared and electric mobility are properly combined, along with automation, we can shrink the number of vehicles on the road and reduce transportation's climate footprint. That's why Uber has launched the EV Champions Initiative, a pilot program for driver-partners to deliver at least 5 million EV rides over the next year.
