Enhance your Intelligent Speed Assistance (ISA) system. Use accurate global speed limit data to ensure legal compliance and driver safety.


Access reliable and up-to-date speed limit data for ISA systems

Nine of ten major automakers choose HERE ISA Map to support the EU Intelligent Speed Assistance (ISA) mandate.

Intelligent Speed Assistance (ISA) is a vehicle safety feature that helps drivers stay within the designated speed limit.

ISA is mandatory on all newly registered vehicles, including cars, vans, trucks and buses across the EU.

HERE ISA Map provides 100% speed limit attribute coverage for all road classes in 180+ countries, allowing vehicle makers to comply with ISA regulations while supporting driver safety.

HERE ISA Map solution ensures accuracy by combining daily-captured high-quality map data with inputs from vehicle camera sensors, local government sources and more.

Know the correct speed limit, even without clear signage

Overcome the limitations of camera-based sign recognition systems. Many signs imply speed limits that cameras may not recognize – such as when entering a town boundary. General road rules and regulations are not signposted at all. With HERE ISA Map, your ISA system knows the speed limit for the current location, whatever the signage.

Provide guidance on local speed rules and regulations

Support safer driving with location-aware and time-sensitive information – based on national, regional and conditional speed limit rules. Access accurate data on the locations of variable speed limit signs, as well as specific speed limit data for commercial vehicles.


Select the right data for your ISA use case

Improve data efficiency for different ISA solutions by downloading only the road topology and selected map attributes you require. Optimize your solution footprint for simpler ISA systems and smaller vehicle segments.
