Amsterdam, Netherlands, 9 April 2026 – TomTom (TOM2), the specialist in mapping and location technology, today announced the launch of Unified Speed Restrictions, a new service designed to deliver fresher, more accurate speed information. Built to support global regulatory frameworks and the next generation of Advanced Driver Assistance Systems (ADAS), Unified Speed Restrictions helps carmakers achieve speed accuracy beyond Intelligent Speed Assistance (ISA) requirements.
ISA plays a crucial role in road safety and driver comfort by helping vehicles stay aligned with the correct speed limit. However, real driver trust depends on more than meeting minimum ISA compliance. It requires exceptional accuracy and reliability in the underlying speed limit information, so the system performs correctly not just often enough to comply, but consistently enough to be trusted.
Unified Speed Restrictions seamlessly fuses TomTom’s full range of static and live speed data sources, including unsigned speed limits, roadside sign recognition, probe data and real‑time variable speed limits, into a single, continuously refreshed and highly accurate speed output. The service ensures vehicle systems always have access to the latest speed information. This improved accuracy and freshness help ensure vehicle systems identify the correct speed limit all the time.
