Definition and improvements of real-time interventions to implement the Safety Tolerance Zone concept of H2020 i-DREAMS project

The H2020 i-DREAMS project aims to establish a framework for the definition, development, testing, and validation of a context-aware safety envelope for driving called the "Safety Tolerance Zone" (STZ). Main goal of i-DREAMS project is to create a platform that, considering driver background factors and real-time risk indicators related to driving performance, continuously monitors and assess in real-time the driver state and driving task complexity, to determine whether the driver is within the acceptable boundaries of safe operation. In addition, safety-oriented interventions will be developed to inform or warn the driver in real-time and at an aggregated level after the trip via an app- and web-based gamification coaching platform (post-trip intervention).

The main purpose of this paper is to present the efforts and improvements made during the i-DREAMS project in relation to real-time intervention: it highlights the progress made in the selection of indicators, the definition of real-time interventions and the thresholds of the indicators used. All these elements have been updated and finalised in the last months in view of the real needs for the implementation of the i-DREAMS Safety Tolerance Zone (STZ).
