Subaru Corp. has added two test tracks to its Bifuka Proving Grounds in Hokkaido, Japan, to help aid the development and testing of advanced driver assist technologies and autonomous vehicles.

The carmaker says it is investing 3 billion yen ($26.4 million) in the site, which also includes upgrades to existing tracks, to better replicate public roads and real-world driving conditions. Testing at the new tracks will begin next month.

A new 2.6-mile high-speed circuit features a multilane track to simulate a four-lane road, merging and diverging lanes and curves simulating those found on expressways. There also is a paved concrete section that mimics North American freeway surfaces.

The other new track is an urban road course that simulates two-way traffic on roads with one lane each way. There also are several different types of intersections, including a European-style roundabout.
