Today Mapbox announced the launch of its ADAS SDK product with Intelligent Speed Assistance support. Intelligent Speed Assistance (ISA) is an in-car safety system that warns or prevents drivers from exceeding the legal speed limit. Mapbox ADAS SDK provides the map data with speed limit information for the ISA function. 

Mapbox delivers the only ADAS SDK with daily updated map data. Mapbox updates speed limit information every 24h from millions of sensors to accurately and quickly reflect real world changes for the safest driving experience all whilst being the most bandwidth-efficient map product on the market.

According to European commission data, 30% of fatal injury crashes are the direct result of excessive or inappropriate speed. Fully adopted ISA systems has the potential to reduce collisions by 30% and deaths by 20% according to the European Transport Safety Council data. As a result, the European Union General Safety Regulation (GSR) has mandated that every new passenger vehicle model sold in Europe introduced in 2022 and onwards is equipped with an always-on display of the current speed limit and with a system to warn drivers when they exceed it. Starting in 2024, this regulation will include every new car sold in Europe.

The ISA function of the Mapbox ADAS SDK delivers 95% accurate speed limit coverage and enables automakers to meet the GSR standards that requires 90% speed limit accuracy. More than 10% of European speed limits change every year, which means that maps without frequent update cycles won’t be able to ensure GSR compliance and adequate safety experience. Mapbox daily map update cycle means that cars equipped with Mapbox ADAS SDK consistently exceed the GSR requirements every day, and not just at the beginning of the vehicle lifecycle. This enables OEMs to provide a safety product with a consistent quality - every day Mapbox speed limit data is updated from millions of data sources, including live vehicle detections from the roads.

“Safety is baked into the fabric of our navigation solutions and Mapbox ADAS SDK with Intelligent Speed Assistance provides an additional toolset for drivers to get from here to anywhere safely. Mapbox ADAS SDK with Intelligent Speed Assistance serves the freshest data in the market to ensure always up to date information. Our live intelligent location platform provides daily data updates to ensure continuous compliance and exceptional safety and driving experiences for customers.”
Garrett Miller, General Manager of Navigation at Mapbox

Mapbox ADAS SDK also enables automakers to augment their ADAS functions including predictive cruise control and powertrain management with accurate speed limit, road curvature and road slope information.

According to an EU study, accurate cruise control behavior both improves driver comfort and reduces road fatalities by 18%. For drivers, accurate speed limit information is a major safety factor as speeding increases the risk of crash fatalities for drivers. An added benefit of speed limit adherence is a lower total cost of car ownership with reduced fines and up to 20% lower insurance premiums.

The Mapbox ADAS SDK delivers efficient daily map data updates to all connected vehicles based on sensor data and active user feedback. This ensures best possible data accuracy and freshness. The Mapbox proprietary Predictive Tile Caching algorithm brings bandwidth usage for map data to less than 100 Mb/month. The Mapbox ADAS SDK can also be deployed as an offline solution. This allows automakers to bring safety features to cars with limited or no connectivity at all. The Mapbox ADAS SDK data includes all EU conditional speed limits in which a speed limit applies only under specific circumstances (e.g., rain, fog, vehicle type). This is a major factor in the accuracy of the Mapbox speed limit dataset.

The Mapbox ADAS data is available today for evaluation on Android through these instructions. Developers can evaluate Mapbox ADAS map data quality in this online evaluation tool. Mapbox ADAS SDK has lightweight modular architecture and can run on a wide range of automotive hardware, including infotainment systems that don't support visual navigation. Daily updates, bandwidth efficiency and integration flexibility enable carmakers to bring important ADAS safety features to a wider range of vehicles, making roads safer.
