Toyota will begin testing its autonomous vehicles on open roads starting in December, using a system compromised of six laser radar devices mixed with higher-accuracy map data. The vehicle is able pass through electronic toll collection gates and main roads, while safely maintain its lane location.

"We will actively continue the development of autonomous driving technologies, but we are considering commercializing autonomous driving technologies that do not change the sovereignty of the driver," said Moritaka Yoshida, Toyota Chief Safety Technology Officer. "For Toyota, advanced driving assist technologies are for safety and realizing zero traffic deaths."

Last year, Toyota publicly showed its automated highway driving assist (AHDA) technology, with the ability for the car to automatically control gas and steering.

There is a larger effort by automakers to create autonomous vehicles - not just assisted driving features - and testing on roadways is an important step to see how technology has evolved.
