Researchers develop one-of-a-kind virtual city for driverless car

IOWA CITY, Iowa (KCRG-TV9) The University of Iowa is now testing its driverless car in a "one of a kind" virtual city.

Researchers call this virtual environment "Springfield." It's a 285 square mile city that's slightly larger than Chicago.

The simulation environment features a number of different roads and driving conditions. Those conditions include different times of day, traffic, ice, and rain.

Researchers say "Springfield" will let them test the driverless car in real-world driving conditions. The university says it's the world's first large- scale multi-use driving simulation environment.
