Research: Cars can be safer without human drivers

Worried about how technology-enabled, driverless cars will be able to navigate through intersections without crashing into one another?   No need to, according to researchers at Virginia Tech Transportation Research. Automated intersection controllers will be able to help cars through faster and more safely than if humans were driving, they’ve found. The research by civil engineering professor Hesham Rakha and PhD student Ismail Zohdy recently won the Best Scientific Paper Award for North America at the Intelligent Transportation Society World Congress in Vienna.
