TomTom (TOM2), which designs and develops navigation and mapping products, has completed the expansion of its high definition (HD) map product to the entire mainland US interstate network, excluding Hawaii and Alaska.

Now, TOM2 HD Map product covers over 185,000km (115,000 miles) of interstates and highways across the country.

The company, with the availability of more than 246,000km of the TomTom HD Map coverage globally, is further strengthening its footprint as well as increasing its leadership in location technology for autonomous vehicles.

TomTom Autonomous Driving head Willem Strijbosch said: “It’s a significant milestone to have completed the full interstate road network in the United States, which is crucial both strategically and commercially.

“Combined with the great traction these products are receiving from our partners in the industry, and our recent acquisition of Autonomos, this is a further testimony of the scalability and efficiency of our approach to enabling autonomous driving.”

In January this year at Las Vegas, it was reported that majority of attending original equipment manufacturers (OEMs) are evaluating TomTom HD Maps.

At the Geneva Motor Show, it was announced that the TomTom HD Map will be integrated with the Volvo Drive Me project, an autonomous driving pilot with real people on real roads.

The latest expansion brings TomTom’s global HD Map and RoadDNA coverage to 246,000km, including interstates and highways in the US plus Washington DC, motorways in France, and Autobahn network in Germany.
