About

Challenge:
Ensuring that vehicles adhere to speed limits and other road regulations is crucial for road safety and Intelligent Speed Assistance (ISA) acceptance. Tradition ISA systems often lack the precision and connectivity needed to provide accurate, real-time speed limit information, especially at the lane level.

Our Solution:
We integrate lane-level accurate localization with connected ISA technology. This combination allows vehicles to receive precise, real-time speed limit data and other regulatory information directly from road infrastructure and other connected sources. The system ensures that vehicles can adjust their speed accurately according to the specific lane they are in, enhancing compliance with road regulations.

Impact:
Lane-level accurate and connected ISA significantly improves road safety by:

  • Ensuring vehicles adhere to speed limits and other regulations with high precision

  • Increased acceptance of ISA functionality

  • Enhancing driver awareness, and

  • Supporting the development of safer autonomous driving systems.
