Executive summary

The Intelligent Speed Assistance (ISA) will help drivers better acknowledge legal speed limits to reduce the frequency and severity of accidents will become a mandatory requirement in several vehicle types from 2022.

In this paper, Continental, HERE Technologies, and Elektrobit describe the challenges involved in making ISA an industry-standard feature and show ways on how to implement such systems: from basic systems using only onboard vehicle cameras to more sophisticated architectures incorporating cameras, location data, digital maps, and electronic horizon technology.
