NAVTEQ's Content Portfolio – Where ADAS Fits in
For a number of years, NAVTEQ has led the way in developing digital map data attributes for the ADAS market. At its core, this has meant developing a digital representation of the road with an accuracy specification that meets the functional demands of ADAS. This can be significantly different than what is expected for navigation.
To meet this challenge NAVTEQ has invested years developing proprietary tools and processes to create digital map data for ADAS. This has required creation of state-of-the-art data measurement and processing technologies to build an ADAS-grade representation of roads, and reaching new quality benchmarks to meet market needs. Additionally, NAVTEQ has drawn upon the inventiveness of our researchers and engineers to create and accurately model the road in three dimensions.
Some key map attributes support ADAS:
1. Enhanced Geometry: NAVTEQ offers geometry developed to the precise specifications required by advanced driver assistance systems (ADAS). Although requirements vary by application, an absolute accuracy of +- 5 meters and relative positional accuracy of +- 1 meter is thought to be sufficient for most ADAS use cases currently being pursued.
2. Curvature: Road curvature is information that enables or enhances ADAS applications by providing a preview of approaching curves.
3. Height and Slope: Slope and height is information about the road that enables or enhances ADAS applications by providing a preview of the vertical road trajectory.
4. Speed Limits: NAVTEQ Speed Limits provide information about maximum speed on a road, thus enabling applications to warn users against violation of traffic restrictions.
5. Lane Information: Extended Lanes and Lane Markings expand the capabilities of the NAVTEQ database to support advanced functionality of the traditional navigation experience. Extended Lanes enables applications to guide the user to the right lane on complex junctions with voice, text or visual cues. Lane Markings visualize the appearance and type of lane separators between lanes, and show arrow directions for a specific lane (e.g. for exit lanes).
Attributes like Enhanced Geometry, Curvature and Height and Slope have broad usefulness across a wide spectrum of applications in Active Safety (like Adaptive Frontlights), Driver Information (like Curve Warning) and Fuel Efficiency (like Predictive Cruise Control). While the suitability and usefulness of specific map attributes is best determined by those building ADAS solutions – the table below offers one perspective on value-adding content relative specific ADAS applications.
