Ushr Inc. Expands HD Map Coverage for General Motors to More Than 400K Miles in United States and Canada

14 September 2022

Ushr Inc. has expanded its high-definition map database for General Motors to cover more than 400,000 miles of roads in the United States and Canada, enabling the automaker to double the road network for Super Cruise*, the industry’s first true hands-free driver assistance system.

For this expansion, Ushr utilized precise LiDAR data and proprietary algorithms to map primary roads. These include undivided high-speed roads, like state highways, that separate the direction of travel with paint lines. Hands-free driving on undivided roads requires precise vehicle localization. This driving scenario demands a high level of HD map accuracy that only Ushr provides across North America.

“Primary roads are far more complex than highways,” said Dr. David K. Johnson, chief scientist at Ushr. “They contain a higher diversity of road objects, density of crossings, pavement types and lane types.”

LiDAR map data is critical to the safe deployment of advanced driver assistance systems (ADAS) at General Motors, as it is a key component in “sensor fusion”, where precision LiDAR map data, real-time cameras, radars and GPS create a sensory field around the vehicle that assist in keeping it centered in the lane while elevating the driver’s comfort and convenience.

“When ADAS is done right, it’s safe for everyone on the road,” said Chris Thibodeau, chief executive officer of Ushr. “For many drivers, this is their introduction to hands-free driving and it’s important to present it to the public in a deliberate way. The industry needs to get it right.”

*Always pay attention while driving and when using Super Cruise. Do not use a hand-held device. Requires active Super Cruise plan or trial. Terms apply. Visit for compatible roads and full details.
