10/29/2018 - Berkeley transportation researchers are addressing the emerging era of smart vehicles with a project that uses machine learning to manage traffic where autonomous, semi-autonomous and manned vehicles share the road. They presented their project, called Flow, at the Conference on Robotic Learning.

5/7/2018 US News & World Report - Start-up-turned-tech-giant Waze solves traffic problems for some users, but creates challenges for others by overwhelming local streets. "There's nothing inherently wrong with routing apps, but the problem is overuse," says Alexandre Bayen, director of Berkeley's Institute of Transportation Studies.

Where are all the driverless cars?

Self-driving car being tested

4/4/2018 Car Connection - Firms testing self-driving cars have slowed their programs, and did not beat a path to the door of the California DMV, which on April 2 was to begin issuing permits for testing on the state's roads. Berkeley transportation engineer Steve Shladover says that's because those companies are still trying to work out some challenging wrinkles.

1/30/2018 - Has your smartphone traffic app ever led you into a traffic jam? Professor and traffic engineer Alexandre Bayen, director of UC Berkeley’s Institute of Transportation Studies, is working on smarter apps that will actually talk to one another to prevent clogged freeways and city streets.
