A new technology developed by University of Michigan engineers is transforming how traffic signals are optimized, replacing traditional manual traffic counting methods with a system that utilizes GPS data from vehicles.

At a time of growing concern about the safety of self-driving vehicles, a leading expert is calling on the federal government to develop a national driver’s test that such vehicles would have to pass before they could travel on public roads.

Smarter vehicles could mean some of the most dramatic changes for the traditional traffic signal since the yellow light was added more than a century ago.

Sensors and ground truth software from RoboSense will help Mcity Test Facility researchers widen data collection abilities, officials said.

U-M's Mcity will soon have a new director.
