TomTom has launched High-Definition (HD) Map and RoadDNA products to boost driverless vehicle testing on public roads in California and Nevada, US.

The areas covered by TomTom’s products include all interstates, freeways and highways in Nevada, as well as all freeways and highways in California.

Through the technology, the Dutch manufacturer provides precise border-to-border model of the road as well as an optimised longitudinal and lateral view of the roadway.

These features facilitate localisation and manoeuvre planning that is important for autonomous driving.

TomTom management board member Alain De Taeye said: "Automated driving continues to push boundaries."

"With this new HD map coverage, TomTom is proud to offer map coverage for three of the four US states where bills have been passed to allow testing of automated vehicles."

TomTom’s HD Map features a map infrastructure that delivers a real-time representation of the roadway profile, along with information provided on curvature and terrain.

"Automated driving continues to push boundaries."

RoadDNA helps converting a 3D point cloud of roadside patterns into compressed, 2D image of the roadway that can be used in-vehicle with limited processing requirements.

RoadDNA data can be combined with vehicle sensor data to decipher the vehicle’s lane-level location while driving at high speeds or when there are changes made to the roadside.

When combined with RoadDNA, TomTom’s HD Map delivers a technology that is used to provide data about a vehicle’s precise lane-level location when the vehicle is in autonomous driving mode.

The company provides its HD Map for California and Nevada in XML and Shapefile format.
