Abstract
This report was commissioned by the Road Safety Authority of Ireland (RSA) and aims to examine and synthesise current knowledge in the field of Intelligent Speed Assistance (ISA) in motorised vehicles, with an emphasis on the application of ISA technologies in on-road (field)trials. The review focuses on four key themes which emerge consistently in the ISA literature;safety and the impact on driver behaviour, attitudes and acceptance, impact on the environment and ISA implementation.
