The traditional navigation map contains information about roads, addresses and everything else you need for turn-by-turn navigation. We have added new attributes with TomTom ADA. This product consists of several map attributes to improve ADAS such as gradient, curvature, traffic signs and lane connectivity at intersections and junctions.
Every single Advanced Driving Attribute has its own unique advantages and added value to traditional driver assistance systems:
- Leveraging curvature information from the TomTom navigation map, a vehicle can anticipate a sharp turn. This avoids harsh breaking that would happen when relying only on sensors.
- Gradient information can be used as input for gear selection and speed control. This helps vehicles drive efficiently both uphill and downhill, saving time and money.
- Many cars today rely on a camera to recognize speed limits and traffic signs. But the view can be blocked by another large vehicle, unreadable due to downpour or a sign can be misinterpreted. Traffic signs from the TomTom navigation map correctly anticipate changes in the speed limit, regardless of the circumstances. This is very relevant for NCAP safety ratings.
- For guidance at junctions, roundabouts and intersections, lane information is used to guide the vehicle in the correct lane and avoid last-minute lane changes. In fact, last-minute lane changes are a key cause of accidents, and providing precise lane-level guidance information to the driver can help improve safety.
